I imported a 4k60 video from my iPhone into PD19 and at the very end of the clip, it's stuttering. This is with just importing it into the timeline and playing it back. This happens in both the timeline and when I export it. Something strange I noticed is that if I copy the file again and import it again, the places it stutters is slightly different. Still at the end, but at different parts. Almost like the import is doing something just to the end of the file each time. I tried all the different combinations of hardware acceleration and it doesn't seem to fix it.

If I play the file back on my media player outside of PD19, it works fine.

Any ideas on how to fix this issue? I have a few other clips taken at the same time which all seem to work. It's just this one video seems to have a problem for some reason and only at the end of the clip.

Thanks in advance.

Simply use HandBrake to convert to a constant frame rate of similar quality (frame size, bitrate, codec) and you will probably be fine with this converted clip in PD.

Thanks! It looks like it's because the iPhone recorded at a variable frame rate. Just converting it in handbrake using a constant rate seems to have fixed it. Thanks again.

Correct, some clips will perhaps appear ok in PD if the frame rate variability is minimal, but in my view, basically all phone clips have issues in PD as PD is not very accommodating of highly variable framerates on its constant framerate timeline.
