Preview encoder

-an -c:v prores_ks -profile:v 2 -vendor apl0 -pix_fmt yuv422p10le -movflags frag_keyframe+empty_mov

the above is the default encoder for preview. Does this work for apple M1 too ?? Because I am not getting any preview while processing

Yes it should, the current app doesn’t support live previews like the release version yet. You should be able to click the preview below once the status 50% or more and should be able to preview.

I uploaded a final cut pro project maybe It could read project files like final cut,Adobe Premier,Vegas,Divinchi Resolve,ect.
