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)

2.7 GHz Intel Core i7

16 GB RAM

Radeon Pro 460 4096 MB

    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.

      Solved!
      Converted the original MP4 Mono - to MP4 Stereo,
      In a video converter and uploaded the new file to premiere.


      Might be that any deviation from the usual Stereo channel (at least when project settings are set to stereo), changes the audio speed to 50%.

      Good luck!

      Same here, Video plays well in MS Media player, and 50% when imported to Premiere...

      Issue was first reported Mar, 2019.

      I'm having this issue, as of today, It's Aug, 2021.

      The fact that the issue has still been unresolved, years later... makes me seriously consider other options. Any Final cut users here?

      I ran into this today (July 15 2021) and it seriously impacted my day as I'm on a deadline to finish a project. It's great to have this forum to help find a workaround, but it's also disappointing to see that this has been a known issue since March of 2019. Wow.

        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.)

          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.

          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.

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

          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.

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

            Thank you.

            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
