Proxies, optimized media, and render cache

These tools solve different performance problems. Proxies are alternate source files. Optimized media is Resolve-managed source optimization. Render cache stores processed results to avoid recalculating expensive effects.

What you’ll be able to do

Choose the correct performance tool and verify which media is used for final output.

Work through it

  1. Choose one demanding clip and observe playback before changing anything. Note dropped frames or stuttering so you have a baseline.
  2. Choose a proxy format and location in project settings, then generate proxy media for the clip from the Media Pool. Pick a lightweight supported editing codec and resolution appropriate to your computer.
  3. Use the proxy-handling options under Playback to compare camera originals with proxies. Confirm that switching does not change clip timing or framing.
  4. For a clip with an expensive effect, enable an appropriate render-cache mode and wait for the cached section. Disable the effect or adjust it and observe how cache validity changes.

A mistake to avoid

A proxy cannot repair missing detail or focus. Using low-quality intermediates for final output can bake their limitations into the export.

Your turn

Create a small comparison log: original playback, proxy playback, and cached effect playback. Before a test export, review whether Deliver is allowed to use proxy, optimized, or cached media.
