What is Render Cache and why is it useful?

• A. Render Cache stores pre-rendered segments of the timeline to improve playback performance.
• B. Render Cache stores color grading presets.
• C. Render Cache exports the project.
• D. Render Cache deletes unused media.

Answer: (A)

Render Cache is a feature that saves pre-rendered frames from parts of your timeline so playback can use those cached frames instead of reprocessing all effects in real time. This is especially helpful when you’re working with heavy operations like color grading, Fusion comps, noise reduction, or multiple stacked layers—the cached portions can be played back smoothly without taxing the system each time. You can let Resolve cache sections automatically or render them manually, and when you make edits that affect cached areas, those parts are marked for re-rendering. This approach keeps your playback fluid during review and editing, without exporting or altering your media files.
