Hi everyone, long time lurker here, love the support you guys are giving!
I'm hoping you'll be able to help with an audio sync problem I'm experiencing with videos recorded with the latest iPad 3 (well, that's what I'm calling it anyway).
I believe the iPad 3 recording format is 1080/30p with 44.1Khz / 16 bit audio, but when I match those settings on a Premiere Pro CS5.5 project (or try 48KHz audio as a test), the audio gradually goes out of sync. If the video is several minutes long, it becomes quite obvious, and by 10 minutes, it's terrible!
I should add the file plays back fine on the iPad itself and was imported to a Mac via iTunes. It also plays fine on the Mac itself in Quicktime.
Does anyone have any suggestions on project settings that'd work?
On a related note, I additionally captured the audio using a Zoom H2n which i intended to replace in Premiere, but foolishly I captured it at 48KHz, rather than the 44.1KHz of the iPad video file. Should I resample it?
I actually managed to line-up the 48 and 44.1KHz waveforms from the iPad and Zoom in Premiere quite accurately, but again both gradually go out of sync with the video...
I'm running Premiere Pro 5.5.2 on Mac OSX 10.7.3.
Any suggestions greatly appreciated!
iOS devices have a variable frame rate, and the videos fluctuate between 24p and 30p. It's a headache, but they are not video standard 30p cause the frame rates vary, and it also records 24p as well. Just depends on how it feels when you hit record. Try doing the "new sequence from file" trick should atleast help.
Thanks demon_hunter83, did you mean dragging the video file into the new sequence icon, so Premiere can figure out what settings to use?
If so, I just tried that, but the audio still goes significantly out of sync...
Is there any sure-fire setting (or indeed application) which will edit iPad videos without sync issues?
To update my original post, I have found this problem happens about half the time.
Sometimes there's no issue and the audio is in sync when imported into Premiere, but at other times it's way off.
I did however find a workaround which has resolved the problem on my iPad3 videos which were out of sync and that was to first import the video clip into iMovie on the Mac first, then simply export it again using the 1080p option. The subsequent file is much larger (so there's been an annoying re-encode), but when imported into Premiere, the audio is at least now in sync.
I used this to fix the audio on a couple of the videos you can find on this page (all of which apart from the last one were filmed on the iPad3)
Since the video wasn't exactly critical to start with, I'm not too bothered by the re-encode.
Let me know if this fix works for anyone, and also if anyone comes up with a different solution.
That is not a solution at all. It adds hours of processing to the workflow. I have to edit and publish in Youtube a 1 hour long video every saturday.
Adobe has to fix this. I don't want to move over to Final Cut
I called for support and they said there is no workaround right now. They also instructed to go and report the bug by looking in Google "adobe feature request".
I cannot believe that Adobe Premiere cannot do what $16 software like Imovie can do.
Adobe is not Apple, and does not have the same level of access to the file format as the Apple programmers (my opinion, I do not work for Apple)
If an Apple program does better at editing an Apple format video... use the Apple program
Yes, when dealing with many Apple formats, QT Pro (only the Pro version will do the conversion) is a good conversion tool. I still find it to be a less-desirable player, but that is another story.
I had an issue with an Iphone 5 where the Audio was out of sync on the timeline, however it played fine in media player and quicktime player.
Open the file in quicktime, go to save as and save as a refrence movie under a differnt name. use the new created file. import and your done.
