prores comes to mind (it has several advantages over
transparency in vpx) but you should try hard if you cannot
reduce the bit-depth of your sample, that may lead to
better output.
In general: Please provide the command line you tested
together with the complete, uncut console output (that would
tell us if my suggestion makes sense), do not top-post here
and please remove the footer from emails sent to a public
mailing list.
