Interpreting footage from 29.97 fps to 24 fps is creating duplicates frames.

Help!

Working on a feature documentary with archive footage of different frame rates. The project is 24fps.

In the last few days I've noticed that when interpreting 29.97fps material as a 24fps it's adding duplicate frames which gives it a stuttered look. This is also happening when interpreting other frame rates as 24fps.

I feel like I'm going crazy, because I'm pretty certain that when I've done this in the past it's simply slowed the clip down by the requisite amount - to include every frame from the 29.97 footage in the 24fps timeline.

I'm doing this via the 'modify clip/intepret footage.' And for 25/29.97/50/60 fps footage...

I updated to 24.6.3 not so long ago and wondering if this is a bug in this version?

Pulling my hair out on this and can't see a releavant post on here addressing it - which makes me feel even more crazy.

Any help really appreciated.

Don´t interpret the footage from 29,97 to 24 fps, just drop the native 29,97 footage directly into the 24 fps timeline. This is often the best way to go.

Thanks Averdahl,

Many thanks for responding to this.

But - from my understanding - if I just drag 29.97 onto a 24fps timeline, won't it drop some frames from the original source footage? I understand that if you had two cameras for an interview and one was 29.7 fps and one 24 fps that just dropping on a timeline would work to keep both in synch with audio.

But since this is BRoll and archive without audio - to go over V.O - slowing it down isn't an issue.

I'm sure in the past this has worked fine. It simply included all the frames from the source clip to the timeline - so a 29.97 was slightly slow mo.

What I don't understand is why it is creating duplicate frames, rather than just including all the frames on the 24fps timeline?

I just can't figure it out, and wondering if it's because I updated to a more recent version of Premiere and interpreting footage is done differently than the previous version.

In short, I'm just trying to figure out how I retain all the frames from a 29.7fps clip in a 24fps timeline without dropping or duplicating any.

Thanks again!

I just did a small test in Pr 25..5.0 and had no issues there when interpretting 29,97 > 24 fps for use in a 24 fps timeline or using 29,97 footage in a 24 fps timeline. No duplicated frames.

How does the original footage look? Load the 29,97 clip in the Sourcce panel and step forward one frame at a time to find any duplicated frames. The duplicated frames you see may already be baked in into the original 29,97 footage. This has happened to me and it took some time to find that they were already there from the start.

If you see duplicated frames in a timeline, go to Sequence > Sequence Settings and make sure that the Timebase and Display Format is both set to 24 fps.
