Quicktime audio imports at half-speed.

[Tychonoir]

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)

2.7 GHz Intel Core i7

16 GB RAM

Radeon Pro 460 4096 MB

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?

Windows 10 Professional, CC2019

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

Still amazed there isn't a solution here, but exporting audio through GarageBand and reassembling in Premiere worked for me.

[DirkV71 · Accepted solution]

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 DirkV71​ saved 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.

[Trent Happel]

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

Thank you.

I am having the same issue. I use a PC, though.. is there an alternative to Quicktime that can solve this?

[Trent Happel]

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.

[andi_urra]

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.

[Trent Happel]

Thank you for the confirmation!

I'm having the same problem as of Premiere Pro CC 2020 as of 2/12/20. Any status updates on this bug?

[joaop.santos]

Hi.

I'm having the same problem.

macOS Catalina - 10.15.4

Adobe Premiere CC2020 - 14.1.0

Hi Trent!

This is happening to me with videos I saved from TikTok, with only one audio channel. I've tried resaving them in quicktime, and using media encoder to reexport them, nothing works. They're stereo H264 files. Running latest Premiere on Catalina 10.15.7. Thank you!

Best,

Sarah

I actually had the problem trying to edit a video to upload to tiktok, weirdly enough, I

 tried importing another tiktok video and it sounded fine, so I uploaded the video file to tik tok privately and then downloaded it and used the downloaded file and it worked. Don't know why, but it did apparently.

[williaml87346308]

This has not worked at all for me....Audio when imported separately to video just imports in slow motion????

[Ethan5C7A]

I am having this issue as well. I just upgraded to Adobe Premiere after using iMovie and I can't even get two seconds into a project without a major issue like this. What's the point of paying so much if you can't even import a simple clip with audio?

[brandonk87794107]

so never got around to fixing this?

[JPremiere79]

I put my videos in Media Encoder exporting them at a similar setting and then imported back into Premiere and WALLA!!!! works fine. 

[Smayo_85]

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

Hey, I just had the same problem.  I ran the clip through handbrake and it imported just fine.  That seems to always be the work around, run it through handbrake. 

[beladossantos]

I was just having this issue as well and it didn't seem like the original file was quadrophonic. Exporting audio through Quiktime didn't work, and neither did Media Encoder (with a few basic settings I tried). I ended up dragging the movie into Garage Band....the basic export from there saved it as .m4v which ultimately worked when imported into Premiere. Wild! (Now to spend another two hours searching this community for help with captions import in the new Premiere.)

[Im5E80]

Yeah, so far my only solution after a while trying to solve this is:
Re encode as an .mp4 under a different file name, even though the file is already a .mp4. I no like this bug.
