10 bit
Can the DVCpro codec process in 10 bit? Tonight I was doing some color correction work and I started to see some banding. I dropped it into a 10 bit SD Sequence and rendered, the banding went away.
I can;t remember if you can work in 10 bit with this codec.
Thanks,

DVCPRO HD is an 8-bit codec. If you want 10-bit, you need to drop the footage into a ProRes or uncompressed 10-bit HD timeline.

My suggestion if you are doing major color correction is to consider your DVCPROHD timeline ‘offline’. Render out the final version to ProRes or 10 bit uncompressed and you’ll get the best possible renders.

I have not played with the ProRes codec much. It sounds like you guys recommend that format for finishing?

Sure it’s awesome quality. Love it.

Converting the footage to ProRes doesn’t give it 10-bit depth though. It’s still 8-bit footage, carried in a 10-bit basket. Just like the EX1 and XHG1/XLH1’s HD-SDI output, those are 10-bit streams (because the HD-SDI spec is for 10 bits) but they only use 8 bits, the last 2 bits are set to zero.
So once you bring it into a 10-bit codec you’ll be able to do transitions and grading in 10-bit steps, but you’ll still be working from an 8-bit source. 256 levels of gray, not 1024. It’s better to do grading in a 10-bit system of course, I’m just saying that it doesn’t magically “become” 10-bit, it’s still an 8-bit source.

Exactly- that’s an important distinction Barry brings up. You can never unscramble the egg. What you can do by going to a high quality is not make the egg ‘more’ scrambled and you can add new ingredients in a very pristine way.

YEs, this I know. My footage will always be 8bit. But as I added a filter, did some color adjustments I saw banding in the sky. By dropping this into a 10 bit uncompressed sequence and doign a re render it solved the banding problem I was seeing.I went from HD to SD uncomressed 10 bit. I am guessing the results would be some what the same for 10 bit Pro res codec. I’ll have to try it.
