MOV from iPhone won't play in sync in PTs
I recorded a 22 minute video on my iPhone (6Plus) set at 1080p/30fps (QT Inspector shows Format: 1920X1080 AAC 44.1 mono 29.98FPS). When I import this MOV (with audio) into Protools the video plays back out of sync with the associated audio (that came from the MOV itself). I'm finding a fair amount of discussion on the issues with H.264 files. Just wondering what the best standard practice is to get the video to play accurately in Pro Tools? If converting to another format is the solution, what do people use for the conversion?
Puzzling to me is that I get H.264 videos from Media Composer regularly for my post work that play fine in Pro Tools.

Re: MOV from iPhone won't play in sync in PTs
I've heard something about the Apple/iOS interpretation of "30 fps" is in fact not at all what the rest of the world call 30fps. (I believe Russ from the Pro Tools Expert team has mentioned it on the podcast. Something like 30.1 fps - but I could be remembering that wrong.) If you find something meaningful about this, please update this thread about it. I'd also like to know.

Re: MOV from iPhone won't play in sync in PTs
I remember reading a thread about this on an Apple user board; apparently the iPhone records video at various frame rates depending on the lighting conditions - the brighter the shot, the higher the frame rate. (!) The fix is to import the video into iMovie and export it again at the desired frame rate, which will be stable.

Re: MOV from iPhone won't play in sync in PTs
i would expect it to say 29.97 (not 29.98) ... that is odd ... have you tried the imovie or QT conversion to see if it helps ??

Re: MOV from iPhone won't play in sync in PTs
I've tried exporting from QT player to 1080P before importing to PTs but that didn't help. Next I'll try exporting from iMovie. I'm just hoping to NOT lose too much quality in the transcoding just to get the damn thing to play in Pro Tools. As I said, the end product has to be "Bounced to move" from Pro Tools so I'm stuck with that file format as an end product.

Re: MOV from iPhone won't play in sync in PTs
I did a sound post-production for a short recorded with an iPhone. And I would say, the frame rate iphone uses for capturing video (and audio) is really strange (I do not remeber the exact number of fps). We ended up with transcoding all recorded material to 25fps and then did the video edit and audio post for it.
To my best knowledge, a direct import a iPhone video into ProTools will not work. Kuba |

Re: MOV from iPhone won't play in sync in PTs
As I remember, Avid Media Composer was used. But I was not involved in the exact process (a machine room guy did it), so I cannot give you more details.
This was 1second = 1second method, so the actual speed of sound wasn't changed. Kuba |
