Frame “split” glitch only after export
Seemingly every other time I export a version of this video, there is one single frame at some point throughout that “splits” as seen below. It does NOT appear when watching a rendered preview in Premiere (CC 2015.4, just upgraded). Only after rendering. Very frustrating. Any idea why this is and how I can avoid it on export? Please let me know if you want further details. I provided a bunch below. Thank you!

the first two things that pop into my head are change video renderer to software from cuda and disable intel h.264 acceleration in preferences. if those don’t work, then deselect import seq natively and delete media cache.

If your specs on export are just a typo and you are actually exporting at 23.976 you might try making your video previews ProRes and then, if it plays without the glitch in your timeline, exporting using your previews.
And you can also try to export using Media Encoder instead of exporting directly from PP. Perhaps you have already tried this.
This might help you isolate where the problem is (assuming you are exporting the same frame rate).Neal Broffman

Good factors to consider, Chris. I’ll keep them in mind if I experience this issue again.

Dave, your frame rate explanation makes sense. I figured frames would be interpolated to accommodate the higher frame rate, and the audio stayed in sync, so it never looked off to me. I’ll definitely keep this in mind next time.
