Audio/Video Synch Issue (sometimes)

Question

Hello, I am running Premier Pro CS6 on an HP ENVY with an Intel Core i78565U CPU @ 1.80GHz 1.99GHz. with 16GB RAM

I have had an issue (at times) with the audio/video synching after importing it.

EXAMPLE: I record 7 videos with my phone, and import them all. 6 of the 7 will be fine - no issues whatsoever. But the other one might be 'unsynched' (visually) while in the timeline. As I watch the segment, while the length of the audio and video are the same, and they are linked, but the video appears to be slower. If I watch the video alone in another player (VLC, RealPlayer etc) the video/synching is fine.

The particulat file in question this time is a 10.4GB file.

Should I just trust that it is indeed in synch? That perhaps it is a 'cache/GPU/RAM issue' but that it really is in synch?

Thanks!

If the footage is variable framerate convert to constant framerate with Handbrake or Shutter Encoder before bringing into Premiere.

Phone footage tends to be of variable framerate which can cause out of sync issues: you can check this with MediaInfo
