When I have app. 50 (AVC and MP4 ) HD clips in the timeline the edit mode (scroll and move) are very slow, and lacking behind.
This is extremly annoying.
I have tried to use proxy files, but that does not help.
The display setting are set to HD and realtime
I also have magix MEP and Sony Vegas on my machine, theese programs are much "snappier" and there are no lacking at all in edit mode with the same clips/fotages
Any good ideas ?
