Hello all
Raw video from machine visions can be handled like that
ffmpeg -threads 4 -f rawvideo -pixel_format bgr24 -r 16 -video_size
2332x1752 -i reel02_dec -pix_fmt rgb24 -vcodec qtrle -r 16
another example for 48 bits
ffmpeg -threads 4 -f rawvideo -pixel_format bgr48 -video_size 2332x1404
-i Reel3976_dec -pix_fmt rgb48 whatever_codec_one_wants_to_use
I believe trying to incorporate it into Cinelerra is a bit pointless,
if anything an export in TIFF files proves to work faster and Cinelerra
is already equipped for that.
Depending on the machine bgr24/48 may need to be rgb24/48. I use either
of them depending on the camera I use
Only if my assumption of the rawvideo concept is what we are talking
about here !CheersEd
