How can i export 8k 360 3D stereographic video in h.264 codec with FCPX?

How can i export 8k (7680 x 7680 pixel) stereographic 3D video with FCPX in H.264 codec?

I can do it as ProRes but files are ten times the size - 30Gb for one minute footage.

When i try exporting h.264, i get the error ""Frame size settings in the output exceeds the allowable dimensions of h.264 format."

I know 8k 3d stereo 360 is non standard h.264 codec size but the original was created in Insta360 Pro 2 Stitcher software - so it can be done.

I tried Hybrid Video encoder but no longer supported by Mac.

Any suggestions - other than Adobe Premiere?! :)

Big thanks !

Mac Pro, macOS 10.14

Thanks Tom ...

I'm no expert, so I've tried to look into this and h.264 does actually support 8k 3d, it's just a non

standard format and it seems FCPX doesn't support it. It'll import but not export.

This was an interesting read - but sadly Hybrid app no longer supported by Mac. :(

I guess it was a proprietary development. Perhaps Premiere supports it, though likely it would have to be on a Windows machine.

High Profile H.264 only supports resolutions up to 4K 4096x2048. I don’t know what the stitcher application is doing, but probably not recompressing the video.

Yep - apparently Premiere does support too - but i bought FCPX.

I've asked Apple to support this format in future release. It would make life a lot more simple.
