This provides the advantage that your computer has less work to do in realtime while editing: decoding, scaling, and effects. This is, quite simply, because there are less pixels to compute. Then, when you are ready to export, it will use the original (or optimized) files for full quality. Performance is optimal when the pre…

• 720p is a good choice when working on a 4K screen or with 4K UHD footage and you want to get a

Regardless of what I choose will export be the same?

Is there a difference between preview scaling and proxy?

[Emaad_Dar]

Nevermind i see

After I export how do I delete the proxy files

[bentacular]

In the proxy files settings, you can set it to a folder on your desktop so it’s easy to find and delete. It’s under “Storage”
