Mac .264 Frame Size

I have a custom display of 7680x1080 that I produce content for.  Before the 2017 upgrade, I could EXPORT A QuickTime Animation at 7680x1080 from AE and then use Media Encoder to re-encode to .264 at the same frame size.  Now there seems to be a 4K limit to the width of .264 frame size.  My only work around is to use Apple's Compressor for the .264 encoding.  I primarily work on PC.

Is there a reason for the imposed resolution limit to .264?  Any way to work around it?

Thank you

I'm 98% sure (but not 100% sure) that your issue ties into the deprecation of QuickTime (which Apple has been replaced with AV Foundation Frameworks).

Assuming that's correct, a QuickTime file allows you to use the CODEC with an out-of-spec frame size while the H264 format does not.

HVEC (H265) should allow you to create the larger, custom frame size movie, assuming that your workflow allows for a MP4 using H265 instead of H264.

So AV Foundation Framework is now the container and puts the limit of the frame size of the H.264 file? This seems to apple to OSX and iOS platforms.  But I am working on a Windows 10 machine.

I would love to use H.265, however the playback unit does not support it yet. Thank you for the information.

No, it's not AV Foundation Frameworks.  It's the H264 specification.  QuickTime allowed you to work around that specification limit.

So, another way to put this is that you need QuickTime to generate the non-spec frame size.  The way to access that would be using Apple Compressor (I assume it was Compressor 3.5 that you were using as Compressor 4 and up are based on AVFF.

Also, I'm just making an informed guess here.  A lot of the non-standard frame size work that I've done relies heavily on QuickTime.
