Quicktime audio imports at half-speed.

Something changed. I used to be able to import quicktime .mov files into Premier just fine, and now it doesn't work.

The audio is perfect when playing the .mov in quicktime, but upon import into Premier, the audio is at 50% speed, while the video is at the normal speed.

I've seen this problem mentioned in various places, and the answer seemed to be to upgrade quicktime.

Well I've now upgraded everything and it still doesn't work.

What now?

Mac OS X 10.14.3 Mojave

Quicktime 10.5

Premier Pro CC 13.0.3

MacBook Pro (Late 2016)

Ok, I discovered something peculiar.

If I create a screen recording using quicktime and soundflower, the video audio imports fine.

If I create a screen recording using quicktime and an aggregate device (with soundflower and mic), the audio imports at half speed.

(Soundflower is used to let quicktime record system audio.)

Unfortunately, the aggregate device is the only way to get quicktime to record both mic audio and system audio at the same time.

I don't know what the issue is, exactly, or how to fix it.

I'm trying other screen recording tools, but so far they are awful. I looked to see if CC had something in the bundle I could use. The "All Apps" plan apparently doesn't include Captivate. I thought maybe Rush would include some kind of screen recording since it's aimed at YouTubers and such. It doesn't, so now I'm really not sure of the point of that app over Premier. /rant

I am experiencing the same problem. In my case it is h.264 .mov files. I checked and found that CC2018 (Premiere, Audition) import them correctly. But CC2019 (Premiere, Audition) get it wrong, at half speed.

VLC, Quicktime Player, Elmedia Player, DaVinci all get it right. This must be a new bug in CC2019. Adobe?

I recommend hardware recorders for screen capture that you intend to edit.

Hi Tychonoir,

Remove Soundflower and report back. It created a lot of trouble going back a few years.

Thanks,
Kevin

I have the same problem. My workaround is that I save video and sound with Quicktime separately and reassemble in Adobe Premiere ... a solution would be nice anyway.

Edit: Solution by DirkV71saved my files! Thank you Dirk. All you have to do is open the files with Quicktime, click export Audio only, and then re-assemble in Premiere.

------------

I have this issue and I really would love if anyone had a solution for my .MOV files. I have recorded 4 hours of content with Quicktime screen recorder and external microphone, and it always used to work when importing into Premiere. The audio is exactly at 50% slower pitch for some reason. Speeding up does not help. I recorded with Sierra OS. I tried dropping them into Resolve and it doesn't have the audio there at all. The videos all play back fine when opening anywhere (Google Drive, Mac OS) so that's why I continued recording. Trent Happel​ I saw another thread where the user PMed you so he could share his file with you. I have an 8 second file that both myself and a friend with Premiere can reproduce the issue with. I really hope that we can save my files in some way because it's really strange that the videos play totally fine but Premiere imports with 50% slower audio. It seems like the data is there it's just being read wrong.

If all of you could supply us with samples files, that would help with investigation.

Thank you.

Thank you for the sample clip lucass51819268! With that clip, I was able to determine that this appears to be an issue with clips with quadraphonic audio. Current versions of Premiere Pro are importing them incorrectly as stereo with audio at half speed (as all of you have painfully noticed). I was able to create a screen recording with quadraphonic audio with same results. I have submitted an issue for investigation by our Developers.

Possible workarounds include suggestion by DirkV71 to open the files with Quicktime, click export Audio only, and then re-assemble in Premiere (or save video and audio separately). Another possibility is to edit the clips in Premiere Pro 12.1.2, which should not have this issue (although I did discover that audio channels might be mixed up a bit, which I have also submitted an issue for)

If anyone is running into this issue that does NOT have quadraphonic audio, please let us know and provide a sample clip if possible.

Thank you.

I can confirm that it happens to clips with 4 audio channels. We had a film shoot with varying numbers of channels (from 3 to 8) depending on scenes. The issue only shows on the dailies (.MOVs) with 4 channels. The original WAV recordings that were used to create the dailies play correctly. Only after it is rendered into a video file the problem shows.

Can you give more detail on how to do that? I've never used media encoder, but do use Premier Pro CC.
