As Andrea noted
ffv1.mkv preset no longer works, file encodes but crash cingg on reimport.
ffmpeg itself behaves .. strange
ffmpeg -i zeldaHQ.flv -c:v ffv1 -default_mode 0 -frames 100 mkv_tedt.mkv -loglevel debug
only muxes 3 frames?
ah, this one was due to misuse of frames, now it must be -frames:v but ffv1 mov also failed, as well as ffmpeg (cli) encoded ffv1 mkv but adding coder=ac range_mode=off qtable=8bit allowed encoded file to import. slowly (160*120! slow!)

----
but same command with -an (no audio) muxes all 100 frames ?!
vp8/vp9/theora mkv profiles seems to be unaffected
