Mixed frame rate on one timeline

[Blaise Douros]

Interpreting the footage to 25 means that you’re playing back the 29.97 clip in slight slow motion. Is that your intent? If you want it to play back in actual real time, just put it on the timeline and Premiere will interpolate the frames. You can even set the clip’s interpolation to Optical Flow, render it on the timeline, and in your export, select the option that allows the exporter to use rendered timeline clips.

Is the clip in an h.264 format? XAVC, AVCHD, MXF? Try doing a Render and Replace of that clip in the timeline, to something like ProRes or a DNx flavor, and see if that helps. Sometimes Premiere gets twisted up on Long-GOP clips, sometimes for no reason at all.

Finally, try switching to the Software Only renderer. It’s slower than the OpenCL renderer, but way more stable.

Hi, Thanks, but I may need more assistance.

I think the 3rd shot it, https://www.graememcmahon.com/drone-reel Premier didn’t do a good job at interpolating. Yes, I cheated shooting at 29.97 as I wanted it slightly slower, but I’m not really fussed how it plays back, just not staccato.

I try the clips interpolation to Optical Flow. The line above the clip remains yellow (whatever that means), and rendering it does nothing. The proxy I make of it becomes a frozen image too.

I export (cant find the option to export option that allows the exporter to use rendered timeline clips). Still, video is stuck at 1 frame.

“Try doing a Render and Replace of that clip in the timeline, to something like ProRes or a DNx flavor, and see if that helps”. How do I do that?

“Finally, try switching to the Software Only renderer. It’s slower than the OpenCL renderer, but way more stable.” I did that through Project Settings/general. No change.

Thanks

If you’ve already interpreted the shot to 25p, than you’ll want to turn interpolation off (or rather, back to Frame)–there’s no need for it, since the clip will now be playing frame-for-frame, slightly slower. If you haven’t interpreted the clip to 25p, then you’d need to mess with the interpolation.

I think the key here might be that it’s a HEVC clip. I’ve found that despite Adobe’s claims of universal compatibility on the timeline, Premiere doesn’t like Long-GOP formats, and it likes h.265 even less.

To Render and Replace on the timeline (which would replace the clip with a transcoded version, solving the h.265 problem if that’s what is really the issue), right-click the clip in the timeline, and select Render and Replace. You’ll get a dialog with several codec options, and then Premiere will render a version to the new codec.

Sometimes I have better luck with sending it to Media Encoder from the export window, and then selecting the Software Renderer there.

Good luck–I hope one of these suggestions helps. I hate problems like these, dealt with one last week.

Thanks.
I just changed it with media encoder.
