Hi guys,
so I've gone through various threads to understand how Premiere handles slomo but I can't solve my problem:
I have 50fps footage. I pull it onto a 25fps timeline, Premiere drops half the frames and displays it running at real time as if it had 25fps, so far so good. Then I stretch the clip to 75% playback speed, which considering the 50fps source material, means that some frames will be dropped. BUT it shouldn't mean there suddenly are duplicate frames. Yet there they are, right in there, those nasty buggers.
Is there a way for me to prevent that? Do I need to import from a 50fps timeline? So confused. Thanks guys!

Did you try this with Optical Flow checked?

I haven't, but the thing is, since there are more frames in my source material (50fps) than I would need to play out (37,5 fps), I shouldn't need frame interpolation anyway. That's why I'm so confused.

off the top of my head, it seems you wouldn't get better than 50% as that would be maxed at 1:1 before premiere started creating duplicates again to fill in the last 25% of "missing data" to slow down. you can either:
1. 50% speed
2. frame mix
3. pixel mix

sorry, but that doesn't make sense to me. 75% is faster than 50%. If I went to 50% I would use all of my 50fps. But I'm only going to 75%, so it should actually drop some frames, not duplicate them. Let alone interpolate.

Is source footage definitely 50p and not 50i?
I wish I was at home right now, because I'm working on a project with 60p clips in 30p sequence with lots of 50% slow motion, which looks perfect...I want to try 75% and see if I have the issue you describe because you are correct, doesn't seem like there should be duplicated frames.
Thanks
Jeff

Have you tried putting your original 50p clip on a 50p sequence and then slowing down to 75% just to see how it looks. If that's acceptable, you could render the timeline out at 25p and re-import into you working project. also, if the clip plays as you want it, rather than render out, you may be able to nest the sequence into your working project. Not sure how well that would work though!

Hey Jeff,
yeah it's most definitely 50p. So weird.
