Chroma and Luminance
Hi Cow Community,
I recently finished a job where we got a QC report on the final version and my graphics were causing Chroma and Luminance to peak. I am some what self-taught in Photoshop and After Effects and I don’t know how to make sure this doesn’t happen in the future, without changing the color in the Avid. Is there any tip on how to check the graphics before I insert them into my cuts.
I used…
Photoshop CS
After Effects 6
Avid Media Composer 11Thanks for any help.

First rule of thumb. Never use color combinations over 235,235,235 White. or 16,16,16 black, for broadcast.
If you keep everything below 235 and above 16 you should be ok in most cases.

That makes sooooooo much sense I can’t believe i didn’t think of it. The simplest answer is usually the right one.
Thanks for the tip though this is great.

As insurance, you can apply the broadcast safe filters,( and should have those warnings turned on at all times ) but it is always better to make it right from the start than to apply bandages to the problem footage.

Something I have always done that has never failed me yet is to put an adjustment layer on the top of your master comp in AE, apply levels filter and adjust the outputs. I only don’t set it as high as others have suggested. I do mine at 8 for black and 247 for white. Never been rejected for broadcast and when I have had the opportunity to test on proper scopes etc it all comes up ok.
I’m in PAL land so not sure that makes a difference though.I think there was a tutorial about this ages ago here.
