Encoding question

Assume I have an .mov file captured with my iPhone. It's framerate is something like 59.0XXXX (they differ a bit from file to file).
What happens if I recode it with Handbrake (with h.265 for example) to 60fps (constant), but decides to "copy AAC audio" instead of recoding it.
Is there a chance of getting audio sync problems when doing this? Is it safer to recode the audio aswell?

I'm fairly sure HandBrake should compensate for that. When in doubt, there are three things you could do, in order of security:
  1. Transcode to VBR, this should be supported by most players
  2. As you suggested: recoding the audio, losing some detail in a lossy codec
  3. Experiment ;-)
Yeah, I know, I'm of no use here. :lol:

The duration of your video should not change, therefore your audio should be ok.
