I notice when I am editing two video tracks, when on Video 1 I am using the
same resource (file) as Video 2, everything stutters. Similar when I had
the cache size to zero.

yeah, there is bug entry for that bug (I hit it too) , not sure if there any way around ... if only ffmpeg devs come down from their Olympus to us  ....
