    10-bit output

    Can someone help met clarify this - most of my stuff comes in from BetaSP Component.  Does this come into MCA 8-bit or 10-bit and is this something that can be changed in a setting somewhere?  Also, in the Digital Cut tool I now have the option to output at either 8 or 10-bit.  I usually send back to tape (again BetaSP) at 1:1, 10-bit.  Do I gain or lose anything by 8 or 10-bit? I guess I'm still very much in the Meridien mindset.

    Re: 10-bit output

    If you set in Media Creation your file format to MXF, you will get the option to capture 1:1 10bit in the Capture tool.  Working in 10bit is superior especially when you have many effects to render.  As for 10bit output, I'm sure it's better than 8, as it requires more renders on the timeline.  I'm curious myself what's the difference between a tape laid off at 8 vs. 10 bit.  Anyone?

    Re: 10-bit output

    thanks for your info...I was wondering about the deal with 1:1 10-bit.  In the old days with meridien I used to digitize all my footage at 2:1, 3:1 or lower to speed up rendering, and then re-digitize the final sequence to 1:1 for output.  But now Adrenaline allows multiple resolutions in the same timeline...

    If I want to go 1:1 10-bit MXF for output, will I need to digitize this from the start, or can I start off with OMF 2:1 or lower?  I trying to find a workflow here that won't crank up the render time too much.  I do a lot of greenscreen work and to output at 1:1 10-bit would be great, but not lenghten my render time.  I'd appreciate any advice on this.

    We also do many blue screen work. We capture diectly in 1;1, in 8bit OMF, but why not try the 10bit MXF solution. Can't say if rendering time is higher, must experience it. Anyway capture in low resolution and batrch capture in 1;1 is (in our situation) "old fashioned". We have enough space to have simultaniously several projects on hard drives  in 1;1.

    CorneScheepers:

    If I want to go 1:1 10-bit MXF for output, will I need to digitize this from the start, or can I start off with OMF 2:1 or lower?   

    When you do digital cut, just select 10bit instead of 8bit, and you be laying down 10bit video if the format allows it.  Someone correct me if I'm wrong here.

    For all your compositing work, it would be advantageous to capture at 10bit MXF, then when you render at 16bit, you will be getting the best that Adrenaline can give you.  But this applies to capture...for output, I'm still hoping someone can explain the benefit, if any, of a 10bit digital cut over 8bit. 

    Does it improve image quality on the tape?  Will it help later when that tape gets digitized?  Thanks.
