Audio Issues With DSLR Footage
I’ve imported footage from 3 cameras: 5D, 60D, and T2i. Most of it plays perfectly in Premiere, but maybe 1/3 of the clips have skipping audio. I’ll have 4 clips off of the same SD card from any of the three cameras and 2 clips play fine while 2 clips skip audio. No changes in camera settings. Luckily, if I open the funky clips in QuickTime, they play perfectly, so I know I could export them to another format and work with that, but does anyone have another idea for how to get them working right in Premiere? Is this unusual? It’s just especially weird that it’s happening with footage from so many different devices and cards, and so inconsistently (though the problem clips remain constant). Thanks for any suggestions!

Hi Alex,
Do all the audio sample rates match your sequence?
That’s a common issue with mixed footage and that’s where I’ d start.

Thanks for the help.
They’re all 48KHz and all the same format. That’s what’s so weird to me. I’ll have one clip that plays properly, and then the next clip won’t (though they all play properly in QuickTime). I have three cards from three different cameras and all of them have clips that play correctly, yet also have clips that have messed up audio in Premiere.
For instance, on a single CF card from a 5D, I shot a 2 minute clip, stopped recording for a minute, then recorded again; the first clip plays back perfectly and the next one skips and drops audio. No change in any settings that I’m aware of. I’d say it was my card or the camera or even the operator, except that it’s happening across three cards from three cameras and I haven’t asked Premiere to interpret any clip differently from the other (AND it plays perfectly in QuickTime). Any other ideas?

This might be a silly question but it might help:
Have you checked the frame rate? And specifically which camera did the audio come from?
Your audio problem isn’t of the jerky sort where there is audio and then suddenly no audio and then audio is back again right?

Add:
I meant as in which cameras the problemetic audio comes from, is it always the 2nd clip after the 1st good one?
I had a similar problem before and mine was due to frame rates.

I’ll be more specific:
The audio issue is this- when opened in Premiere (source monitor or placed in timeline), the video plays fine, but the audio will play about 2 seconds, then jump ahead 2 seconds, and play 2 seconds, then jump ahead, etc. It winds up ending early and depending on the length of the clip, usually the second half of the video just has no audio simply because it had already jumped through it and reached the end. The waveforms reflect it, too. Again, the clips all play perfectly fine in QuickTime, so I could workaround by exporting them to another format. This project is a music video and the audio was just for reference so it’s not worth that, but I’d still like to sort out the issue.
It’s occurring so widely, I’m pretty certain it’s a Premiere or settings in Premiere thing, not cameras or card issue, but here are the camera specifics:
We shot at 24 fps on the 5D. 8 clips are fine and then the last two have the audio issue in Premiere.
We shot about 30 clips on a T2i. Most were at 60 fps and I interpreted the footage in Premiere to playback at 24 (23.976). Though obviously I won’t be using the audio from those clips, they seem fine. In the middle of those clips are a handful of clips at 24, and they do have this audio issue.
We have about the exact same sort of footage and issues with clips from the 60D as the T2i.
Any ideas? I wouldn’t be surprised if this was operator error and someone just needs to say, “Did you check this box?” but it could also be a bug in the program- or maybe just funky files that QuickTime can handle and Premiere can’t.

Did you ever sort this out? I’ve just come across this identical issue this afternoon and it’s going to be a big problem if there’s no easy solution. Same gear as you I think… new iMac Pro, CS5.5, Canon 5D. Files are fine in iMovie and QT – audio missing chunks and bunched up so that it finishes too early.

I found a way to sort out the problems I was having. I deleted all the cached files and then re-imported the clips just a few at a time – and didn’t do anything until they were all conformed. I think the error occurred at the conforming stage. All seems fine now.

Thanks for posting your solution. I never solved my issue, but I was able to get away with it because it was a music video. It wasn’t more than an annoyance for me, luckily. Glad you found a way to make it work. Hopefully the issue will be fixed before I am working on a project where it’s a big deal!

I’m the latest victim of this problem. Tried deleting the related cache files and reimporting but am getting the same problems with the same set of clips. Again, this clips are the same as others. I’ve even tried opening a new project and only importing these clips but I get the same problem, even before they’re added to a sequence.
Any advice is highly appreciated.

I had the same problem with DSLR Footage.
The problem was solved.
1. Remember the clip numbers that have this problem.
2. Go to Edit/Preferences/Media in your Premiere and click Clean Cache
3. Quit out of premiere.
3. Go to Media Cache Files folder (by default on PC this folder is located C/Users/-your user-/AppData/Roaming/Adobe/Common/Media Cache Files)
4. Delete all the files that have corrupted files name in it. It should be 2 cache files for each video file *.pek and *.cfa (might be more)
5. Open premiere and import one by one each corrupted file, giving some time after import for the file to be confirmed.
