i like this tool very much, got no script wout it but ... i'm not always sure about what i do. some quests:
-what's the difference betw levels="PC->TV" and opt="coring"? (i was surprised when i noticed that the latter makes also some modification. before i'd thought it just defined the scale to be used.)
- what does opt="coring" exactly make? does it cut-off the 'invalid' values or does it make (re)scaling? (i'd love rescaling:-) if the latter, is it a frame based operation or does it act like 'levels'.
- what's the order of execution? the function has couples of args. if i pile up a lot, how coloryuv decides on the order.
say, i wanna do 'black-to-black' modification (a luma shift), but i don't want y values out of tv specs ("coring"). here, the order is very important.
thx
