This file contains some media which isn’t compatible with QuickTime Player.

[rafis2354997]

I updated my Mac, and AfterEffects has been a little wonky since. I just finished a project. It included some 3d layers--nothing I haven't used before, though. After it exports quicktime says, "this file contains some media which isn’t compatible with QuickTime Player." It asks if I wish to continue, and when I click yes it makes the video into an audio only. It's super annoying. I thought it might be because of some effect I used, so I screenrecorded the preview then exported the audio and put it over it. Still does not play. Somehow even the screenrecording .mov has "some media which isn’t compatible with QuickTime Player" which simply makes no sense. 

I hate this. 

Please help.

The biggest problem you have is that you did not check the compatibility of Catalina and Adobe Products. Apple dropped all support for 32-bit code of any kind in OSX 10.15. That includes their own Quicktime player. You just jumped the gun. You are either going to have to roll back to 10.14 or wait for AE, and probably a bunch of other apps to be updated. Old files that used codecs that were coded in 32-bit may never work again in QT unless you transcode them into a fully compatible format.

Apple and Adobe both warned users. Just about every Mac blog or forum or news source also gave out the warning. I think you even get a warning when you choose to upgrade. Adobe is not the only company that is having problems with the latest upgrade and there was not much they could do about it, but I can guarantee you that they have people working on the problem. Every 3rd party plug-in developer is also going to have to make sure their software is fully 64-bit compliant.

Warning or not it makes no sense to go backwards with an update.

setting the render to Apple ProRess 4444 (whatever that is 😛 ) works

u r the worlds biggest yt saver!

thx so much everyone do this!

[Amber15B9]

Yah.. I tried that and I can't get it to complete the export because it is trying to convert to a 40+ GB file!!!! D:

Amber - Try setting the video codec to ProRes 422 instead of 4444. It'll be a smaller file. If that is still too big, there are other codecs in that same list that you can try.

Purge it

It's before I render that this pops up. It pops up when I try to open clip from my desktop or external drive.

How do I get to the "render" in order to do that?

[kriskristferson]

"It's your problem" is not helpful in any way whatsoever but thak you so much anyway.

I rendered out through Media Encoder as H.264 and then voila, worked perfectly.

Also I converted the mov file from After Effects as well in the same way and this worked as well 

[03ghxsted]

i used media encoder and my video was in really bad quality. it also wouldnt send to my phone when sending it through imessage from my macbook

[rubenarthe]

Thank you! A real solution. 

[ji123456]

Yes!  I also used Media Encoder to render the non-functional file out as H264...and the new file worked great!

[Void_Enoch]

i dont have H.264 or nun of that what do i do?

[phincycle]

Great! What are you talking about?

[oliviao94369627 · Accepted solution]

For anyone else with this problem, make sure you're not exporting using the Animation codec (Output Module Settings > Format Options > Video Codec dropdown). This codec isn't supported in newer versions of macOS Catalina. Use the Apple ProRes 4444 lossless codec instead and you should be fine.
