When I cull my footage I like to cut clips to a timeline of clip selections and pull from it when developing my main sequence. My footage is all shot in 59.94. When I slow down a clip on the 23.976 "clip selections" sequence up to 40% it looks great, no problem. When I copy a slowed down clip from this sequence to my main sequence that is also 23.976, it plays back choppy as if it is now interpretting the clip as 23.976 footage on a 23.976 timeline and therefore unable to be slowed down with smooth motion.
Is this how premiere is supposed to handle this? I feel like this wasn't always an issue for me.
follow-up: I've tried putting my clip selections timeline in 59.94fps, removing speed changes and copying to my 23.976 timline and it's yielding the same results when I slow down a clip.
Now what's really making me scratch my head is I've tried pulling the clip directly from the media bin to my main sequence and it still plays back slowed down clips choppy. The sequence settings of my main sequence and clip selection timelines are identical aside from frame size. I have my main sequence setup in a 2:35 ratio at 3840 x 1634.
