Proxy Editing Definition

Why proxy editing matters for video teams

Modern cameras capture footage in resolutions and bitrates that often exceed what editing workstations can handle in real time. A single stream of 8K RAW video demands enormous processing power and storage bandwidth just for smooth playback. When an editor needs to work with multiple streams simultaneously — multicam edits, layered compositions, or complex color grades — even high-end systems can struggle.

Proxy editing solves this by creating lightweight stand-in files that mirror the original footage at a fraction of the file size. Editors make all creative decisions using these proxies, which play back smoothly on any hardware. Once the edit is locked, the system relinks to the original high-resolution masters for color grading and final export. The creative process is identical; only the underlying file weight changes.

This workflow is not a compromise — it is standard practice at every level of professional video production, from independent filmmakers to Hollywood studios. The proxy-to-master relink is built into every major NLE.

Best practices for proxy editing

Choose a proxy resolution that balances visual clarity with performance. For 4K or higher source material, 1080p or even 720p proxies are common. The goal is smooth playback, not pixel-perfect evaluation — that comes later. Use consistent codec choices (ProRes Proxy or DNxHR LB are industry standards) to ensure predictable performance across your editing team.

Organize proxies with clear naming conventions that preserve the relationship to source files. Most NLEs handle relinking automatically if folder structures and filenames follow conventions. Automate proxy generation as part of your ingest pipeline so footage is edit-ready the moment it arrives. Avoid manually generating proxies on an ad-hoc basis, which leads to incomplete coverage and wasted time when an editor discovers missing proxies mid-session.

Establish a proxy deletion policy. Once a project reaches final delivery, proxies consume storage without providing value. Automated cleanup after project archival keeps storage costs manageable as production volume grows.

How ShotAI relates to proxy editing

ShotAI can index both proxy and full-resolution files, enabling fast visual search across your library regardless of which resolution tier you are browsing, ensuring editors find the right shot before committing to a full-resolution conform.
