iPhone videos audio cuts out
on Jul 13, 2016 at 4:29:37 pm

Hey guys

I'm trying to make a vlog using videos from my iPhone 5s. I am only dragging down the video (not the audio) and am using an external song I've downloaded. In the beginning of editing, the sequence playback will go: song plays, song cuts, song plays, song cuts - about every other second. When I play back the sequence (once i have 6+ seconds), the song will play for about 1 second, cut out, and then only continue to play after the iPhone videos are finished playing.

Also the iPhone video files, when put into the actual sequence, do not contain audio, however when played in the individual preview they do contain audio. Not that I want to use the iPhone videos' audio, but maybe that's a contributing factor.

Can someone please help? It's very frustrating.

Thank you!

What file type is your music track. Id it still generating Peak files when you start your work? If it is still conforming in the timeline, that may be why you are getting intermittent sound - at least at first.

If you are not using any audio from your iPhone clips, you can select them all in the bin, right-click, and select "Modify". From there you can go into the audio tab and tell it to not use any audio tracks. You can even save that as a preset for future use. When you pull your clips to source or timeline after that, they will not have audio tracks come with them. (Your original clips are not permanently changed.)

transcoding to handbrake should convert iphone variable frame rate to constant frame rate. (not to be confused with constant bit rate). Adobe products do not support variable framerate.
