FFMPEG expand limited range to full 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
