What does 'proxy editing' refer to in video editing?

Proxy editing refers to the process of using lower-resolution versions of video files during the editing phase. This approach is designed to enhance system performance and streamline the editing workflow, especially for high-resolution files that may be too demanding for standard editing setups.

By working with these lower-resolution proxies, editors can make cutting, trimming, and manipulating edits more fluid and efficient without the lag or delays that can accompany high-resolution footage. Once the editing process is complete, the final outputs are usually rendered using the original, high-resolution video files to ensure the best possible quality in the end product. This method is particularly important for projects involving complex visual effects or high-resolution formats, as it allows for smoother playback and faster editing without compromising the final quality of the work.
