When I render a long video made up of component parts, random parts are blacked out. It changes each time I render it. No rhyme or reason. Sometimes a complete clip, sometimes partial, sometimes they have fx, sometimes not.
I unticked "Close media files when not the active application".
I'm at a loss.
On a side note, movie studio 12 had a video switch called "disable resample". Is there an equivalent in 14?
