If you deliver a project digitally, AVID DNx codec, do color bars still mean anything?
I sent a still of the 720 60 color bars directly out of final cut to a client. They came back and said that my whole system is off, crushed blacks and hot whites.
When I edit, I don’t look at bars, but make sure I am within legal. As most editors, I like black to be black, and so that is by choice.
In the digital HD world, no tape, do color bars tell you anything?Isn’t the digital hd broadcast specs from 0 ire to 100 ire?
The client is king, so I will conform to what they want. I’m just seeking “big picture” knowledge.
They suggested I buy a blackmagic scope, but I use the final cut scope, visible at all times, in addition to the waveform on my Panasonic waveform, so I don’t feel an addition scope will solve my problem.
Please advise!Todd Reid

Trouble is, Codecs in FCP can be RGB or 601 / 709.
And, gamma is different from the rest of the world.In your case, your client is probably right. You delivered levels from RGB 0,0,0 to 255,255,255.
Also, if you’re not on the latest version in Snow Leopard, your gamma is off.My standard procedure is NOT color bars, but 3 vertical bars, black, mid grey and pure white.
This way the other side can see what i mean with black, gamma and white, and thus compensate.
If they work on Avid, and you did NOT render to DNxHD, they can import with interpret as RGB, and the levels will match. Gamma still needs a manual correction.
Good thing, it’s probably fixable…
