What is created during the rendering process that aids in effect playback?

During the rendering process in AVID Media Composer, a render file is created to facilitate the playback of effects. Render files contain the processed versions of clips and effects that have been applied to them. When you add effects such as transitions, color corrections, or other adjustments, the system needs to calculate how these changes will appear in the final output. Rendering generates a new file that reflects these changes, allowing for smoother playback without needing to constantly reprocess the effects in real time.

This approach significantly improves performance, especially when working with complex effects or high-resolution footage, since it prevents potential lag or stuttering during editing. Render files are stored separately from the original media, allowing for quicker access during playback. Their purpose is to ensure a seamless editing experience and help edit efficiently by eliminating the need for on-the-fly processing of effects.

In contrast to render files, the other types of files mentioned have different functions. Proxy files are lower-resolution versions of original media, which help in editing while still allowing for the use of heavy effects. Raw files are unprocessed footage straight from the camera, and project files contain the information about the project structure and assets but do not directly aid in playback the way render files do.
