Got some 4K mkvs I'd like to back up to 1080p compliant BD-25s.

While I can import them fine, it seems like it's not scaling them down to 1080p in Movie-only mode.
There's an old thread from a couple years ago - jdobbs suggested using Alternate output but these are not BD-compliant (slices, vbv-maxrate, GOP size, not sure what else is out of spec) even with the ALTERNATE_BLURAY=1 line added.

Any other way to get a compliant 1080p stream out of 4k files?
Thanks in advance!
