[Avid-L2] Re: Can't right click and get source setting in Avid 8.2?

 

That's interesting, I hadn't thought of doubling up. That makes me wonder if the order of the Color Transforms is important too.  My gut would be to expand to full range, like you said then add the LUT below/after that.  I'll have to play a bit more.

As far as the Color Space choice at top I'm pretty sure when I had stuff ama linked it made a difference but I'll have to go back and confirm that.  Just like before LUTs were an option the older source settings you could choose if the source got compressed from graphics to video and vice versa.  Then any transcodes would reflect that level.  I never tried to adjust the color space after that to see if it would alter the video level once transcoded.  My guess is it doesn't.

On a related note I had received a .mga LUT.  Is that a LUT from Apple Color.  It was unusable but a google got me to a creative cow thread where someone had converted the 5D Cinestyle LUT from Technicolor.  I know Arri has a LUT builder on their site IIRC and I read LUT Buddy (which I believe is free) can be used to convert LUTs to other formats.  What is the LUT manipulation tool of choice?  Of course my choice would be forget the LUT and light it the way you want it but with LUTs being this weeks buzz word I have to play along.  I do find the Arri Log C to Rec 709 in Resolve to be quite useful like I with all LUTs would be.

When you are in the color adapter section of the AMA source setting the top color space is just an indication of what MC thinks the source is in terms of color space. I've never found changing it to make any difference but to be safe I set it to what I know the source is.
Its what's in the big box below that is important.
If this is empty then no LUT or correction is applied but it may have a full range to 709 adapter applied.

If you have Rec 709 content and want to use a LUT designed for full range then make sure there are no LUTs in that box. Then add a Rec 709 to full scale LUT then whatever full range specific LUT you want.

You may still get crap results if the LUT was designed to be used with content that had a look applied to it or a specific camera feature.
