Editorial Conform Workflow: How to Conform Edits Across NLE Systems

TL;DR

Editorial conform is the process of recreating or transferring a completed video edit from one non-linear editing system (NLE) to another while maintaining precise timing, shot selection, transitions, and editorial intent. This workflow bridges the gap between creative editing (often done in systems like Premiere Pro or Final Cut Pro) and high-end finishing (in DaVinci Resolve or Avid Media Composer), enabling collaborative pipelines where different departments use different tools. A successful conform preserves every cut, transition timing, and layer relationship from the source timeline, applying them to higher-quality media in the destination system. The process requires meticulous attention to timecode matching, media relinking, and effect translation to ensure the final output matches the approved creative edit.

Key Takeaways

• Editorial conform transfers creative decisions between NLE systems while upgrading to higher-resolution media, different color spaces, or specialized finishing environments without re-cutting
• EDL (Edit Decision List), XML, and AAF file formats serve as the interchange languages that describe edit points, transitions, and timeline structure in a platform-agnostic way
• Timecode and reel name consistency between offline proxy media and online high-res masters is the foundation of reliable conforming—mismatches cause manual relinking labor
• Effect and transition translation varies by format—EDLs carry only cuts and dissolves, XML preserves more complex effects, while AAF retains the most complete timeline information including nested sequences
• The conform workflow typically follows this sequence: offline edit approval → media preparation (transcoding/organizing) → conform file export → destination NLE import → media relink → manual review and adjustment
• Automated tools reduce conform time but human verification remains essential—every cut point, transition duration, and audio sync point must be validated against the original timeline before final output

What Is Editorial Conform and Why It Matters

In modern video production, different stages of post-production often occur in different software environments. A commercial might be edited in Adobe Premiere Pro using lightweight proxies for fast creative iteration, then conformed into DaVinci Resolve for color grading using the original camera RAW files. A feature film might be edited in Avid Media Composer, then conformed to Resolve for finishing, then conformed again to Pro Tools for audio mixing.

Editorial conform is the technical bridge that makes this specialization possible. Rather than forcing every department to work in the same NLE—each with different strengths—conform workflows allow editors to choose the best creative tool, colorists to work in their preferred grading environment, and audio engineers to receive precisely-timed sequences in their DAW, all while maintaining perfect synchronization with the approved creative cut.

The conform process answers a fundamental question: "How do I recreate this exact sequence of shots, with this exact timing, in a different software environment, using different source files?" Without reliable conform workflows, productions would need to either limit themselves to a single NLE ecosystem or manually rebuild complex timelines from scratch—both unacceptable options for professional work.

The Editorial Conform Workflow: Step-by-Step

Stage 1: Offline Edit and Lock

The conform workflow begins before any files are exported. During the offline editing phase, editors work with proxy media—compressed, lower-resolution versions of the original camera files that allow smooth playback on standard editing workstations. These proxies maintain identical timecode and file naming to their high-resolution counterparts.

Once the creative edit receives approval from the director and producer, the timeline is "locked"—meaning no further editorial changes should occur. This lock point is critical because the conform process assumes the editorial structure is final. Any changes after conform begins require re-conforming, which multiplies labor and introduces risk.

At lock, the editorial team prepares comprehensive documentation: a timeline screenshot showing track structure, notes about any complex nested sequences or adjustment layers, audio channel routing details, and a list of any effects that may not translate automatically. This documentation serves as the conform artist's roadmap and verification reference.

Stage 2: Media Preparation and Organization

Before exporting the conform file, the production must ensure that high-resolution master files are properly organized and accessible. This means:

Timecode matching: Every high-res master file must have identical timecode to its corresponding proxy. If proxies were generated with "start at 00:00:00:00" settings instead of preserving original camera timecode, conforming becomes exponentially harder.

Reel name consistency: In multi-camera shoots, reel names (often embedded in metadata or file naming) must match between proxy and master files. A clip named "A001C003_170524_R2FK" in the offline should link to a master with the exact same identifier.

File location mapping: If offline editing occurred on a laptop using local proxies, the conform system needs to know where the corresponding masters live—whether on a shared storage array, LTO tape, or cloud archive. A media database or spreadsheet mapping proxy paths to master paths is essential for large projects.

Format verification: The conform artist verifies that masters are in the expected format (RAW, ProRes, DNxHD, etc.) and resolution. Surprises here—like discovering some footage only exists as proxies—require immediate producer communication.

Stage 3: Conform File Export

The editor exports one or more interchange files from the locked timeline. The choice of format depends on the destination NLE and the complexity of the timeline:

EDL (Edit Decision List): The oldest and simplest format, EDLs are text files that describe edit points using timecode in/out points, reel names, and basic transitions. EDLs have severe limitations—they typically support only one video track and up to four audio tracks, with only cuts and dissolves. However, their simplicity makes them extremely reliable for basic conform scenarios. EDLs are particularly valuable as a verification tool even when using more complex formats.

XML (Extensible Markup Language): Final Cut Pro XML and Premiere Pro XML files contain rich timeline information including multiple video tracks, nested sequences, clip speed changes, basic effects, and motion parameters. XML is human-readable (technically) and can often be opened in a text editor to diagnose problems. However, XML standards vary significantly between NLEs—Final Cut Pro 7 XML differs from Final Cut Pro X FCPXML, which differs from Premiere Pro XML.

AAF (Advanced Authoring Format): Developed by Avid, AAF is a binary format that preserves the most complete timeline information, including nested sequences, complex effects, audio routing, and metadata. AAF files can embed media or link to external files. They're the preferred format for Avid-to-Avid workflows and are well-supported by Resolve. However, AAF's complexity means troubleshooting problems often requires specialized software.

Other formats: Some workflows use JSON-based formats, CSV files with custom conform tools, or proprietary formats like Premiere Pro project files opened directly in other Adobe applications. Cloud-native workflows may use collaboration platforms that handle conform implicitly through shared project databases.

Most professional conform workflows export multiple formats simultaneously—for example, an AAF for the primary conform plus an EDL as a verification reference. The EDL's simplicity makes it easy to spot missing clips or timecode problems that might be obscured in a complex AAF.

Stage 4: Destination NLE Import and Media Linking

The conform artist opens the exported file in the destination NLE. This process varies by system:

DaVinci Resolve: Offers robust AAF and XML import with detailed logging of translation issues. Resolve's "Conform" page is purpose-built for this workflow, displaying the imported timeline alongside media bins and providing tools to quickly identify and fix linking problems.

Avid Media Composer: AAF import is native and highly reliable, especially for Avid-to-Avid workflows. The "Link to AMA" feature allows linking to non-Avid media formats without transcoding, though transcoding to DNxHD/DNxHR is recommended for final conform.

Adobe Premiere Pro: Can import XML and AAF files from other systems, though translation quality varies by source. Premiere's "Link Media" dialog helps locate missing files when automatic linking fails.

Final Cut Pro X: Relies primarily on FCPXML for import. Third-party tools like EDL-X or Xto7 assist with translation from other NLE formats. FCPX's magnetic timeline architecture makes traditional conform more challenging than track-based NLEs.

Upon import, the NLE attempts to automatically link each clip in the timeline to media files on disk. This linking relies on matching:

• Timecode in/out points
• Reel names or clip names
• File paths (if absolute paths are preserved)
• Embedded metadata like camera serial numbers or tape names

When automatic linking succeeds, clips appear in the timeline with full-resolution media. When it fails, clips show as "offline" or "media missing," requiring manual relinking.

Stage 5: Manual Relinking and Verification

Even in well-prepared conform workflows, some clips require manual intervention. The conform artist systematically works through offline clips, using the NLE's relinking tools to locate the correct master file. This process tests the production's organizational discipline—poor file naming or inconsistent metadata turns relinking into detective work.

Relinking strategies include:

• Timecode matching: The NLE searches all available media for files whose timecode range contains the offline clip's in/out points
• Name matching: Searching for files whose names match the offline clip name, ignoring path differences
• Wildcard matching: Using partial name matches when file naming schemes differ slightly between proxy and master
• Manual file selection: As a last resort, the artist views reference frames from the offline clip and visually matches them to master files

Once all clips are relinked, the verification phase begins. The conform artist plays through the entire timeline, checking:

• Cut points: Every edit should occur at the exact same timecode as the original timeline
• Shot selection: The correct take and correct portion of each take should appear
• Transition timing: Dissolves, wipes, and other transitions should match the original duration
• Speed changes: Any slow-motion or time-remapped clips should retain their original speed curves
• Audio sync: Dialog and sound effects should remain in sync with picture
• Track structure: Layers, compositing order, and blend modes should match the original

Professional conform workflows use two-screen verification, playing the locked offline timeline on one monitor and the conformed online timeline on the other, frame-by-frame comparing every edit point. Any discrepancies require immediate investigation—did a media file link incorrectly, or does the conform file contain an error?

Stage 6: Effect and Motion Reconformation

While basic cuts and dissolves usually translate reliably, complex effects require specialized attention. Different NLEs use incompatible effect architectures, so a Premiere Pro Lumetri color effect won't automatically become a Resolve color node.

The conform workflow handles effects through several approaches:

Translation mapping: Some conform tools automatically translate common effects—for example, converting Premiere Pro scale/position keyframes to equivalent parameters in Resolve. Success depends on effect complexity and how closely the NLE architectures align.

Reference screenshots: The offline editor exports frame grabs of any complex composites or effect-heavy shots, along with parameter screenshots showing exact settings. The conform or VFX artist manually rebuilds these effects in the destination system, using the screenshots as reference.

Effect placeholders: The conform file may include markers or colored clips indicating "effect shot here," flagging the conform artist to recreate specific looks. This is common for temporary effects applied during offline (like a rough green screen key) that will be properly implemented during finishing.

Separate VFX conform: For projects with extensive VFX, a parallel conform workflow may send VFX plates (ungraded, uneffected shots) to the VFX vendor, who returns finished VFX shots that get inserted into the master conform timeline at specific timecodes.

Motion graphics and titles present particular challenges. Lower-thirds, animated text, and motion graphics created in After Effects or Motion often exist as rendered clips in the offline timeline. The conform must either use these rendered versions (limiting finishing options) or recreate the graphics natively in the destination NLE using source project files. This requires tight coordination between the graphics team and the conform artist.

Conform File Formats: Deep Dive

EDL: The Universal Fallback

An EDL is a text file describing edit events using a standardized syntax developed for linear tape-to-tape editing in the 1980s. Despite their age, EDLs remain valuable because their simplicity makes them reliable and universally supported.

A typical EDL entry looks like:

001  BL       V     C        00:00:00:00 00:00:00:00 01:00:00:00 01:00:03:15
002  A001C003 V     C        10:04:23:12 10:04:27:03 01:00:03:15 01:00:07:06
003  A001C003 V     D    024 10:05:14:18 10:05:19:22 01:00:07:06 01:00:12:10

Each line represents an edit event with:

• Event number (001, 002, 003...)
• Reel name (the source tape or clip identifier)
• Track (V for video, A1/A2/A3/A4 for audio)
• Edit type (C for cut, D for dissolve)
• Transition duration (for dissolves, in frames)
• Source timecode in (where the edit starts in the source clip)
• Source timecode out (where the edit ends in the source clip)
• Record timecode in (where the edit starts in the timeline)
• Record timecode out (where the edit ends in the timeline)

EDLs have strict limitations:

• Usually only one video track (though multi-track EDL variants exist)
• Maximum of four audio tracks
• Only cuts and dissolves (no wipes, 3D transitions, or effects)
• No clip speed changes or motion parameters
• Limited to 999 or 9999 events depending on format
• Reel names limited to 8 characters

Despite these constraints, EDLs excel at their specific purpose: describing the fundamental edit structure. For a simple interview-style edit or documentary with minimal effects, an EDL may be sufficient for a full conform. For complex projects, the EDL serves as a verification tool—if the main AAF conform produces unexpected results, comparing event counts and timecodes against the EDL quickly identifies problems.

XML: The Flexible Middle Ground

XML files encode timeline information in a structured, extensible format that balances detail with portability. Unlike EDL's rigid line-based format, XML uses nested tags that can represent arbitrarily complex timeline structures.

XML supports:

• Unlimited video and audio tracks
• Nested sequences (a sequence used as a clip in another sequence)
• Clip speed changes, reverse motion, and freeze frames
• Basic motion parameters (scale, position, rotation, opacity)
• Some effects (varies by NLE)
• Markers and comments
• Audio gain and panning

However, XML translation quality varies significantly. Premiere Pro XML exported to Resolve may translate differently than the same timeline exported to Final Cut Pro. Each NLE interprets XML according to its own internal architecture, and what seems like a "standard" often has vendor-specific extensions.

XML's human-readable nature (technically—they're verbose and complex in practice) means advanced users can sometimes hand-edit XML files to fix translation issues. For example, if all clips import one frame off, adjusting the start timecode in the XML header might fix the problem globally. This editability makes XML valuable for troubleshooting, but most conform artists treat XML files as fragile black boxes to be regenerated from the source project rather than manually modified.

AAF: The Professional Standard

AAF files are binary containers that can embed or link to media while storing comprehensive timeline information. Originally developed by Avid to enable interchange between Avid products and third-party tools, AAF has become the de facto standard for high-end conform workflows.

AAF preserves:

• Complete multi-track timeline structure
• Nested sequences with full fidelity
• Audio routing, including surround sound channel mapping
• Extensive metadata (camera logs, production notes, markers)
• Complex effect chains (though effect parameters may not translate)
• Source media in-out points with subframe accuracy
• Clip names, comments, and organizational structure

The tradeoff is complexity. AAF files are not human-readable, and troubleshooting AAF import problems often requires specialized tools like Automatic Duck's Pro Import or Marquis Broadcast's X2Pro. When an AAF fails to import correctly, the conform artist has limited options—try different export settings, use an intermediate conversion tool, or fall back to EDL or XML.

AAF files can be "embedded" (containing copies of media files, creating large self-contained files) or "linked" (referencing external media, creating small files dependent on media being present at specific paths). Linked AAFs are standard for conform workflows, while embedded AAFs are useful for archiving or sending complete projects between facilities.

Common Conform Challenges and Solutions

Timecode Breaks and Discontinuities

Multi-camera shoots sometimes result in footage with timecode breaks—points where timecode jumps forward or backward unexpectedly. This happens when cameras are stopped and restarted without resetting timecode, or when footage is captured in multiple recording sessions.

When the offline edit uses proxies with continuous timecode but masters have breaks, automatic relinking fails. The conform artist must identify which portion of each master file corresponds to each offline clip, often by visual matching of action. Prevention is better than cure: mandate continuous timecode across all cameras and ensure proxy generation preserves original timecode.

Multi-Camera Group Clips

Many NLEs support "multi-cam" or "angle sync" features that group multiple camera angles into a single playable clip where the editor switches between angles. These groups often don't translate well through conform files.

The solution is to "flatten" multi-cam clips before export—replacing each multi-cam clip in the timeline with individual clips representing the chosen angle at each moment. Most NLEs have a "flatten" or "break apart" function for this purpose. The flattened timeline exports as standard clips that conform reliably.

Variable Frame Rate Footage

Smartphones and some mirrorless cameras can record variable frame rate (VFR) footage where frame timing isn't constant. This causes severe problems in professional NLEs, which assume constant frame rate (CFR) media.

VFR footage must be transcoded to CFR before editing begins, not during conform. If VFR footage makes it into the offline edit, the conform will show sync drift—clips that start in sync gradually drift out of sync as the clip plays. The only solution is to transcode the VFR masters to CFR, then re-conform from scratch.

Proxy-Master Resolution Mismatches

Sometimes proxies are generated from a cropped or reframed version of the master—for example, a 4K master might have proxies generated from a center-extracted 1080p region. If the editor reframed clips during offline editing (digitally panning and zooming on the 1080p proxies), those reframes won't translate correctly when conforming to the 4K masters.

This requires either accepting that the online version will have different framing, or manually recreating the proxy reframes as scale/position keyframes on the 4K masters—time-consuming and error-prone work. Better workflow design prevents this: if 4K reframing is anticipated, edit with 4K proxies and apply reframes that will translate to the 4K timeline.

Audio Sample Rate and Sync

Video editing NLEs usually work at 48kHz audio, but audio captured on prosumer equipment might be 44.1kHz (music) or other rates. If audio isn't properly converted during proxy creation, the conformed timeline may show picture-sound sync drift.

All audio should be converted to a consistent sample rate (48kHz for video) before editing begins. If this wasn't done, the audio must be resampled during conform—simple in principle but requiring careful verification of sync across long takes.

Missing or Damaged Media

Sometimes master files are unavailable at conform time due to LTO tape offline, corrupted files, or missing drives. The conform workflow must quickly identify which masters are missing so the production can locate backups or determine if the affected shots can be cut around.

Robust media management prevents this: checksum verification of all masters immediately after shoot, redundant backups, and a media database tracking file locations. When missing media is discovered during conform, the offline proxy serves as an emergency fallback—low resolution but potentially acceptable for brief shots in non-critical scenes.

Conform Workflow Optimization

Pre-Conform Checklist

Professional conform artists use standardized checklists before beginning any conform:

1. Timeline lock verification: Confirm with the editor that the timeline is final and has received all necessary approvals
2. Media verification: Run checksums on all master files to verify integrity
3. Timecode audit: Verify that all masters have valid, continuous timecode matching proxies
4. File organization: Confirm all masters are located in the expected directory structure with consistent naming
5. Conform file generation: Export EDL, XML, and/or AAF using tested export settings for the destination NLE
6. Reference materials: Collect timeline screenshots, effect screenshots, and any special notes from the editor
7. Destination NLE preparation: Ensure the conform workstation has the destination NLE updated to a compatible version with all necessary codecs installed

This checklist catches 80% of potential problems before they delay the conform.

Automated Conform Tools

Several specialized tools accelerate the conform workflow:

Colorfront Engine: An industrial-strength conform and color management tool used in high-end feature film workflows. Engine can ingest complex AAF/XML files and automatically link to camera RAW files based on metadata, generate CDLs for color conforming, and output to various finishing systems.

MTI Cortex: A media management and workflow automation platform that includes conform capabilities. Cortex can monitor for new conform files, automatically trigger relinking processes, and send notifications when manual intervention is needed.

Automatic Duck Pro Import AE: For workflows involving After Effects, Pro Import AE can import FCP or Premiere XML files into After Effects with high fidelity, preserving motion parameters and effect stacks.

These tools reduce manual labor but don't eliminate the need for human verification. Every automated conform must be reviewed before proceeding to expensive downstream processes like VFX or color grading.

Conform Verification Strategies

After completing a conform, verification ensures accuracy before the timeline moves to the next department:

Frame-by-frame comparison: Play the offline and online timelines simultaneously, pausing at every edit to verify frame-accurate matching. Time-consuming but definitive.

EDL comparison: Generate a new EDL from the conformed timeline and compare it to the original offline EDL using text diff tools. Any differences indicate conform errors.

Shot count verification: The conformed timeline should have exactly the same number of cuts as the offline. Different cut counts immediately flag problems.

Audio waveform comparison: Visual comparison of audio waveforms between offline and online confirms sync without needing to watch the entire timeline.

Marker verification: If the offline editor placed markers at specific timecodes, verify those markers appear at identical timecodes in the conform.

Professional facilities build verification time into conform schedules—rushing verification and discovering errors later wastes vastly more time than careful initial review.

Conform for Different Post-Production Scenarios

Offline-to-Online Conform (Traditional Workflow)

The classic conform scenario: edit with lightweight proxies, conform to high-resolution masters for finishing. This workflow dominated film and television for decades and remains common for projects where media size prohibits real-time editing at full resolution.

The offline editor works freely with low-bandwidth media, iterating quickly with the director. Once locked, the timeline conforms to high-res masters in a DI suite with calibrated color reference monitors. The colorist grades the high-res timeline, audio goes through a separate conform to Pro Tools, and visual effects conform to their own master timeline for plate delivery.

This workflow requires military-grade organization—every frame of original media must be accounted for and accessible during conform. Post-production supervisors maintain detailed media databases and backup strategies to ensure conform deadlines are met.

Same-NLE Upgrade Conform (Resolution or Color Space Change)

Sometimes conform occurs within the same NLE but upgrades media quality. A project edited in Premiere Pro with ProRes proxies might conform to the same Premiere timeline but linked to camera RAW files for finishing.

This workflow is simpler than cross-NLE conform since the timeline structure doesn't need translation. However, color space and resolution changes can still cause problems. If the editor applied Lumetri color adjustments designed for Rec.709 proxies, those same adjustments may look completely different when applied to log-encoded RAW files. The colorist may need to strip all color effects and start grading from scratch.

Collaborative Conform (Multi-Site Production)

Large projects sometimes split editorial across multiple teams in different locations, each working in their preferred NLE. The main editor works in Avid, additional editors work in Premiere, and the assembly conform creates a unified timeline in Resolve for finishing.

This workflow requires a post-production supervisor who defines strict interchange standards: what conform format to use, how to structure timelines, naming conventions for sequences, and how to handle effects. Weekly test conforms verify the workflow before final lock. Communication overhead is high, but it allows productions to engage the best talent regardless of their tool preferences.

Archive and Restoration Conform

Archival projects sometimes need to conform decades-old timelines to new NLE systems. A documentary originally edited on film might have an EDL from the negative cutter. The archive conform translates that EDL to a modern NLE, links to new 4K scans of the original negative, and creates a preservation master.

These conforms face unique challenges: old EDLs may use obsolete reel naming schemes, original media may have degraded, and documentation may be incomplete. Conform artists become detectives, piecing together the original editor's intent from fragmentary evidence.

How Modern Tools Are Changing Conform Workflows

Cloud-Native Collaboration

Emerging cloud editing platforms like Frame.io Workflow, Blackbird, and EditShare Flow aim to eliminate traditional conform by keeping all team members in a unified environment. Editors, colorists, and audio engineers access the same project database in real time, seeing updates instantly.

These systems promise conform-free workflows, but they trade conform complexity for infrastructure complexity—productions must commit to a specific platform ecosystem and ensure all collaborators have reliable high-bandwidth internet. For now, file-based conform workflows remain the industry standard for high-end work.

AI-Assisted Conforming

Machine learning tools are beginning to assist with conform challenges like identifying shots visually when timecode metadata is missing or corrupted. An AI can analyze the content of offline proxy clips and match them to master files based on visual similarity rather than timecode.

This technology is particularly valuable for archival conforms where metadata may be incomplete, or for productions with poor media management. However, AI matching requires careful verification—a visually similar but incorrect take could be matched if the AI isn't trained on the specific visual differences that matter for the scene.

RAW Format Conform Challenges

Modern cinema cameras record in proprietary RAW formats (ARRIRAW, RED R3D, Sony X-OCN) that contain massive amounts of unprocessed sensor data. Conforming to RAW presents unique challenges:

• File size: RAW files are enormous, requiring high-speed storage and powerful workstations
• Color interpretation: RAW files need specific color science settings to display correctly—incorrect settings make color matching between offline and online impossible
• Metadata preservation: RAW files contain extensive camera metadata that must be preserved through the conform process
• Debayering: RAW files must be demosaiced (debayered) using quality settings that balance speed and quality

Many high-end workflows now conform directly to RAW files in DaVinci Resolve, which has industry-leading RAW support. The conform artist ensures every clip uses the correct color space and debayer quality settings, then delivers both a graded master and the Resolve project file containing the full RAW timeline for future revisions.

ShotAI: Streamlining Multi-Format Conform Workflows

When your post-production pipeline involves conforming between multiple NLE systems, managing the associated media libraries becomes exponentially more complex. Each conform requires locating specific camera masters across drives, timecode matching between proxy and high-res versions, and verifying that the correct takes made it into the final timeline.

ShotAI's AI-powered search capabilities accelerate this process by allowing conform artists to locate specific shots using natural language queries across heterogeneous media libraries. Instead of manually browsing directory trees or relying on imperfect file naming, conform artists can search "wide shot of car chase, take 3" or "close-up with good focus" and immediately identify the master files needed for relinking. The system's frame-level visual search helps resolve ambiguous cases where timecode metadata is missing or multiple takes look similar.

For productions managing extensive footage libraries during conform, ShotAI provides a central search interface that connects offline reference frames to online master locations, reducing conform relinking time from hours to minutes. Combined with traditional conform best practices—timecode discipline, consistent file naming, and comprehensive documentation—AI-powered media search creates faster, more reliable conform workflows that let creative teams focus on picture quality rather than file archaeology.

FAQ: Editorial Conform Workflow

What's the difference between conforming and onlining?

"Conforming" specifically refers to recreating an edit timeline in a different NLE system, while "onlining" (or "online editing") is the broader process of upgrading from offline proxy media to high-resolution masters for finishing. A project might be onlined without conforming (staying in the same NLE but relinking to high-res media), or conformed without technically onlining (moving to a different NLE but staying at the same resolution). In practice, the terms are often used interchangeably since conform workflows typically involve both switching NLEs and upgrading to higher-resolution media.

Can I conform from any NLE to any other NLE?

Theoretically yes, but practical success varies widely by source and destination combinations. Avid-to-Resolve via AAF is highly reliable. Premiere-to-Resolve via XML works well for most timelines. Final Cut Pro X to anything else requires specialized conversion tools due to FCPX's unique magnetic timeline architecture. Complex timelines with nested sequences, extensive effects, or custom transitions always carry higher risk of translation problems regardless of the NLEs involved. The safest approach is to test the planned conform workflow early in production with a sample timeline, identifying what translates automatically and what requires manual recreation.

How long does a typical conform take?

Conform duration depends on timeline complexity, media organization quality, and whether relinking succeeds automatically. A simple 30-second commercial with good media management might conform in 30 minutes including verification. A 90-minute documentary with 500 clips could take 2-3 days if most relinking is automatic, or a week if extensive manual relinking is needed. Feature films with VFX, multi-channel audio, and extensive grading can take weeks to fully conform and verify. Rule of thumb: budget 1-2 hours of conform time per minute of locked timeline for moderately complex projects with good media management.

What happens if I need to make editorial changes after conforming?

This is the nightmare scenario conform workflows try to avoid, which is why productions lock picture before conforming. If changes are truly necessary, you have three options: (1) Make the change in the offline timeline, re-export the conform file, and re-conform entirely—safest but time-consuming. (2) Make the change directly in the online timeline—fast but risky since offline and online are now out of sync, and any future conform overwrites the change. (3) Make the change in both timelines independently—error-prone but sometimes necessary for minor timing adjustments. Option 1 is strongly preferred for any but the most trivial changes. This is why productions build "VFX lock" and "sound lock" into schedules—hard deadlines after which changes require expensive re-work.
