I'm not sure if it's possible in a single step (as you're trying to do).
As far as I know, ffmpeg generates all output from the given source
(Sequence.01.mov) - not from intermediate-output you created in that
step (Sequence.01.mkv)

I guess you might have to generate the output framemd5 separately
afterwards.

Maybe others here know better?
