Preview is ahead of the timeline

I haven't used Premiere Pro for a long time so I'm not sure exactly what's wrong, but when I try to preview a video, the preview (and the timestamp with it) is about 70 ms ahead of the timeline indicator and any other timeline (such as the keyframe timelines in effects). Does anyone know how to fix this? (I'm using a Macbook Pro, and one thing may be I am editing an .MOV video, but at the beginning, the program told me that my sequences weren't the same type?)

 

Edit: also, when I scroll the timeline indicator up to 29 ms, the preview timestamp jumps to 1 sec.

Is your video from a phone or screen capture?

It's from an iPhone- in addition, while editing my video, when I play the preview, images I've added in appear out of scale, but when I pause the video, they go back the way they are supposed to appear.

Your iphone footage is likely in HEVC codec, which is one of the worst codecs you can work with at the moment, but in combination with Variable Framerate you can get some pretty crazy issues. Here is a little info on VFR: https://www.reddit.com/r/VideoEditing/wiki/faq/vfr

 

You'll want to get that footage to a constant framerate before trying to edit with it. The above link can give you some info on doing that. You can transcode with Handbrake or try one of the other options listed.

 

Anecdotal info on the solutions: FFMPEG is command-line and not very user-friendly. I haven't tried the last one listed on the link so maybe you'll want to look into that (they've added it recently.) I also just tried this the other day: https://www.videohelp.com/software/tsMuxeR which is a remuxer so you wouldn't need to transcode. I've only tested it on a couple of clips so I'm not positive it'll work with your HEVC media, but it might. it remuxes to a .ts format, but Premiere imported that okay for me. You also need to do that one at a time, so if you have a lot of media to deal with you may want to just batch transcode in Handbrake.
