to reduce CPU eating, did you try to put each [pix_video] in a separate pd~
and then send the image to a main patch with [pix_share_*] ?
this could help
I never worked with blackmagic card but it could be possible to add a new
backend to [pix_video] to support those cards "natevely" in pd.
do it yourself
