I've done a bit of searching of the website and there's a hodgepodge of scripts at https://www.mythtv.org/wiki/Transcode_Video, none of which says clearly whether it works for HD.

I recently asked on the list for advice about exporting shows to a
projector (thanks all who responded, the trip was a total success).
The solution I settled on was the sendtonas.sh script discussed and
published here :-
I configured it to drop the output into my videos storage directory
and I pick up the media via mythweb for transfer to the projector, its
very elegant, but it has the advantage that it will deal with lossless
cutting of commercials on H264 streams using mkvmerge. Oh, and it's
written in shell so its real easy to modify for your needs.
