Hard to export 8K60p HEVC above 100Mbps from Final Cut Pro/Compressor #113

Closed lgarron closed 2 years ago

It's easy to export up to 4K60p in Final Cut Pro or Compressor.app:

It's also possible to set up to 8K60p, although that took me a few hours of debugging.

However, Compressor seems to be limited to 100Mbps for 8K60p HEVC (for any HEVC, in fact), and Final Cut Pro seems to be limited to the same Compressor settings.

As a result, I can only output to 8K with extreme blocky artifacts — significantly worse than the quality I'd get for exporting 4K for the same video, which kind of defeats the point of working in 8K.

It's possible to export to ProRes, but that means I have to work with files that are literally on the order of a terabyte in size. And I still wouldn't be able to do anything practical with such files, since I can't transcode them to 8K60p HEVC (for e.g. uploading to the internet) without the exact same problems.

You have to use the "Quicktime Movie" base setting and tweak all these values.
