Re: [Avid-L2] 5D/7D timecode import bug with AMA and QTChange combo

 

Perhaps i'm biased, but the 'change' settings are clear.
Most of them have nothing to do with FPS;
so having the time base in the menu seems a logical choice.
I could move it to the visual interface, but does that make sense?
(if a couple of you think so, i'll do it.)
