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

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.

Re encode through Handbrake that is

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.

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?

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

[Eran2465772261xz]

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!
