An editor creates proxies, edits with them and relinks to the originals for the final render.
What mistakes do people make?
- Forgetting to relink
- Deleting originals
- Not enough disk space
Do skills need proxies?
No. Skills process your clip directly, such as a Layers run. Proxies are for manual timeline editing.
Frequently asked questions
Do proxies reduce quality?
Only during editing.
When should I use them?
Use proxies when footage is heavy, such as 4K, and your computer struggles to play it smoothly in the timeline.
Do they use more space?
Yes. Proxies are extra copies, so they use additional disk space, though they are smaller than the original media.
Can I switch proxies off?
Yes. You can switch proxies off in most editors to preview the original quality, and the final export uses the originals anyway.
