Slow motion - speed ramp - 24fps with 60fps

[jacks11340871]

Here's what we're having trouble with...

We want to have a 24fps timeline on PP.

Then we want to have multiple clips, some of which filmed in 24fps, some in 30, some in 60 and so on.

The 24fps clips play no problem.

But we also want to have clips shot in 60fps so we can have a speed ramp dropping the speed down to 24fps temporarily but then, it will have to come back up to 60.

At the moment, this means our clip (during the 60fps) section is looking very choppy.

Is there a fix for this, or a suggestion for a different way to film to accomplish this?

Maybe filming for slo-mo in 120 and having a sequence at 60 for example?

Any suggestions would be great.

Thanks!

Premiere should be able to do this. I've done a lot of videos the same way as you are describing. What might be helpful to know is if you are aware what shutter speed was set while shooting you 60p footage? If you were shooting with a DSLR and your shutter speeds were above 1/120th of a second with fast moving subjects I think you might notice it looking "choppy".

It was all shot on an iPhone 6/6s. Any suggestions?

As a test try your workflow on a 29.97 timeline. Maybe post a short example clip of what you are working with.

You can't do that in a 24 fps timeline.  Clips will always play at the timeline speed.  So when the clip is playing in "real time" PP is dropping frames to make it conform to 24 fps.

My recommendation is to shoot everything at 24 and use Optical Flow, or perhaps the plug-in Twixtor, to improve the slow motion segments.

What you need to do is right-click on the 60p clips in your project bin, select "interpret footage," and change the interpretation to 24 fps. 100% playback will be in slow-motion, while you can use a 250% speed ramp to get to "real-time."

Hopefully this "interpret footage" fixes some of my issues.

Was dropping a 60fps file on a 24 fps timeline, then remapping the 60fps file down to a speed ramp (700% to 47%)

The 700 looked "iffy" but when the file slows down to 47% it almost appeared to drop frames.  Never really had that issue in 2019 before, but ever since the update in 2020 it's really super extra noticable....and just...bad.

Here's a tut for you.
