Agreed. I know exactly how it's going to be used. I think it's just a matter, as a friend of mine said, that they through some geek talk together, hoping they would sound knowledgable. Of course, the result is the opposite.

For the record, I've never seen an H264 file that was 10 bit or above.

Thanks for the response, Jim.

Going out on a limb and saying that I would presume so.  And Max Bit-Depth would suggest 10-bit, if the codec supports it, which not all codecs do.

With due respect, some clients don't know what they need.  I can't tell you how often I've been asked for "a Quicktime," which is a sign that I have to probe for more information about how they're going to use it down line.

In AME (CS 6) I increased Profile to "Highest" and Level to 5.1, maximum bit-rate and still only get "millions" of colors, which indicates 8-bit, right?

If you look in AME, you can get some pretty high bit rates by choosing the highest numbered "Profile" and "Level" settings.

There's also a Maximum Bit-Depth check box.

I'm searching for a clarity . . .

A client is asking for "H264 with the highest settings, 8bit uncompressed." H264 is, by definition compressed, correct? And though there are in theory, versions of H264 that are 10 bit, the garden variety H264 (created in, for example, Quicktime) is 8 bit.  So the only part of this request that makes sense is "highest settings," right?

Any insights greatly appreciated.
