FFMPEG expand limited range to full range I am working on a recipe to convert Avid DNxHD files which are rec.709 "legal" range (15-235 in 8bpc) to .png files which are "full" range (0-255). In looking around it seems that "colorspace" could do this, but I am quite new to FFMPEG filters and I can't seem to get it to work... I've looked all over the place but not found a solution to this simple question

-i video.mov -fv yadif=0:0:0,colorspace=srgb transcode_%04d.png just throws an error, and I assume I just don't know the proper syntax (no real example for this in the manual, that I could find).

Separately i thought this might work: -i video.mov -vf yadif=0:0:0,scale=in_range=tv:out_range=full transcode_%04d.png. This runs without complaining, but the output .png's are still in legal range.
Whelp finally figured this one out when I stumbled across the answer in another forum. Pretty simple really, just needed to study  up on filtergraphs. And for the record bwdif deinterlacing is FAR better than yadif! Not sure why anyone even recommends yadif anymore with bwdif out there...

-i inputfile -vf bwdif=0:0:0,scale=in_range=tv outputfile.mov
