Same as source will keep it providing you capture is 10b 1:1 or DNX 185x or
equivalent. We did find the cineon files also were 10 bit but there is some
embedded LUT stuff going on that proved complicated to fathom out.

Thanks Michael and Nigel,
Seems like Tiffs are the only way then. Which seems really stupid. I might
do some tests of my own going from after effects or cinema 4d to avid and
back again but it doesn't sound hopeful. I wonder how many people out there
are accepting graphics made as ten bit and not realising what Avid is doing?
There should be a dialog warning that files will be truncated/rounded to 8
bit on import. Ok so say i've imported my 16bit tiff sequence to 1:1x MXF
and whacked it on a timeline, can i now do a same as source QT export and
retain the full ten bits or do i have to export a tiff sequence? Thanks for
all the valuable insight.

And also.. You can export to 10 bit tiff by selecting 16bit tiff.. We
couldn't find another way to export non avid 10 bit files. assuming you have
a 10 bit sequence.

Sorry, Andi -- I missed seeing your message somehow.
If you load 10-bit footage into After Effects, the footage info display
will show it has having 'Trillions of Colors' (vs. 'Millions of colors'
for 8-bit.)
If you import your 10-bit third-party codec QT movie to a 10-bit Avid
resolution, it truncates/rounds the data down to 8-bits of info, even
though it's using a 10-bit format. There's no good way that I'm aware
of to check inside Avid that your 10-bits have been preserved.
You would think that rendering out of After Effects to 10-bit Avid
codecs would do the trick, but last time I tested this (a few months
back), this also truncated down to 8-bits within the 10-bit format.
What does work for sure is to render to a 16-bit TIFF sequence, which
can be imported to a 10-bit Avid codec, retaining all 10 bits of info.
Cheers,
--Michael

not, correct? Are there any better ways to check if a file is 10bit or not?,
inside Avid perhaps? That's really annoying if Avid is truncating,
especially seeing as i went to so much expense to get that file! :-) So I
guess I should be telling them to render out using the Avid codecs then?
It's been said before, but that sucks!
