Hi there! Not quite sure what you're trying to achive: first converting legal range rec709 to full range rec709 and then convert it to normal linear footage?
Getting from legal range to full range could be done with a single grade node. Just use "64/1023" as value for blackpoint and "940/1023" as whitepoint. This expands the values between 64-940 to the range 0-1023. Afterwards you could use a normal colorspace node to convert from fullrange rec709 to linear.

Does anyone know of an elegant solution to legally scale rec709 (64-940) to rgb (0-1023)? I ultimately would like to convert rec709 to linear rgb without having black and white values get clipped. Thanks Paul Fiebiger
