I have recorded test files in the various formats supported by the hyperdeck. Prores has been a block wall. Black magic uses their own implementation that makes it impossible to author correct files with ffmpeg.

DNxHD in mxf wrapper uses a 24 bit linear pcm 16-channel stream. This is what I am trying to create.

I know DNxHD in an move wrapper creates 3 files: 1 video and 2 audio. I haven’t analyzed those files yet, but will tonight as an alternative.

I was able to create a 16-channel stream with:
ffmpeg -i wildlife.wmv -c:v dnxhd -b:v 185M -r 29.97 -s 1920x1080 -flags +ildct -filter_complex "[0:a][0:a][0:a][0:a][0:a][0:a][0:a][0:a] amerge=inputs=8" -c:a pcm_s24le -ar 48k output.mov

The ffprobe of the resulting file shows: 16 Channels (FL+FR+FC+LFE+BL+BR+FLC+FRC+BC+SL+SR+TC+TFL+TFC+TFR+TBL)… Is it possible to assign a channel map of 16 mono channels or no map at all?

I will try the multi-pass.

In order for the Blackmagic Hyperdeck to recognize a clip, it must mee the exact standard for playback. If it isn’t a 16-channel 24-bit LPCM stream, it won’t play it… Thanks Blackmagic…
