Corrupted Frame Rate Exportings

I'm concerned about some of my projects within Premiere Pro (13.0.3). Almost every project I make is intended to be rendered in a 24/23.976 frame rate, though after using a multitude of different videos on one project (with differentiating frame rates), I've noticed that some parts (usually videos that transition/cut to the next) can have a choppy and lagging effect, as if the frame rate has decreased significantly while rendering that specific part of the video (until it transitions into the next cut, in which case it can go back to a normal frame rate). It's extremely odd, and the only way to fix it (or at least how I fixed this problem) was by rendering the finished project with the match video settings which basically just reverts the entire export settings into 60fps (which is not ideal for myself).

It doesn't do this when previewing, and exporting the entire video into 24fps shouldn't be a problem if every video used is all 24fps or higher.

I also used an fps counter on my PC and noticed that even though it lags tremendously, the FPS counter will tell me that what is being played is indeed 24fps.

If I had to assume, this is most likely something that is normal or is bound to happen when using different types of media files and frame rates on one project, but the fact that 24fps can corrupt itself mid-render is not something I signed up for when using CCPP.

P.S. this may be extremely hard to follow, but I wanted to include as much data as possible.

Couple things I want to mention.

1. 24 and 23.976 are two different frame rates.  Don't ever mix them, at least not with sound clips.

2. Premiere Pro will play all media at the sequence frame rate, regardless of the clip's frame rate.  So be sure to set up the sequence correctly.

3. Your export frame rate should always match your sequence frame rate.  If the Match button solves the issue, it's possible this item needs attention.

I was under the impression that exporting the file also changed the source. So yes, this does fix the problem when changing the source frame rate first and then exporting it. Maybe it's a rookie mistake to think that exporting it in the frame rate you want would automatically change the source's frame rate, but the thing is, I have never had a problem like this before and I have been using Premiere for a while. That's why I figured it automatically did. The more you know I guess.

Cheers, thanks.

I'm not clear on what your last post means.

Just to clarify - if you intend to export as 23.976fps and some of the source footage is 23.976, then edit in a 23.976 Sequence.

Say you have 24p clips (23.976) and you edit in a 60p sequence (59.94), those 24p clips are being converted to 60p in the software, so then if you later export as 24p, the quality is now messed up since the clips are being converted 24p > 60p > 24p. Better to have kept the 23.976 clips as 23.976 all the way through the process. Any other odd clips in the mix that are not 24p will be exported as 24p if that is the export setting.

Thanks

If you use those setting on export it becomaes 60 fps because your Sequence Settings are 60 fps. Make sure that the source footage matches the Sequence Settings. If not, problems arises.

Different frame rates (fps) should be avoided since it too many times introduces problems such as choppy video. Where does the source footage come from?

The project uses different videos filmed/recorded off of multiple different devices. For example, I used a Canon 80D to film bits, and I also have an old 2012 Sony handy cam that I used to film. The handy cam does not have a 24/23.976fps setting, only 60fps. You might wonder why I don't just use the Canon 80D for all of the filming, and that basically has to do with artistic merit, and also some footage was filmed when I didn't have the 80D. I used other devices too, such as older smartphone footage, and a terribly old/cheap plastic camera that I cannot remember the brand name of (the quality was horrendous, but had the feel of an old vhs tape).

I can understand the fact that I would need to match the source footage, but the source footage is 60fps, and I personally find 60fps to be off-putting and non-cinematic.
