  • 8.1 upgrade changes key mixer result in grades.

    Posted by Fred Ricci on October 16, 2011 at 7:33 pm

    Hi there.
    I dont see any performance loss, I love the dynamics with curves and the AAf import is flawless.
    I was not in a middle of a project and had rendered everything before upgrading.
    Everything is fine, but I see a difference in grades from older projects, specially if I’ve tweaked the key mixer.
    Anyone’s seen this?

    I ve uploaded an example.
    The before file stands for the grade result before upgrade, the after file is the result after the upgrade and the original file.

    That looks more like a data misinterpreting thing to me.
    Have you checke if your Quicktime/RED files are interpreted scaled or unscaled ?

    Hi Sascha, thanks for answering.
    I thought that myself, but I am allways normally scaled, and I didnt use aces color wich allows you to change the interpretation of files. This example comes from a prores baked sequence, and only the grades with layer/key mixer have this result. If I change the imput gain from 15 to 38 I get almost the same result as the “before” grade. The rest of the sequence is prety much balance/power windows and didnt change as much, but are slightly less saturated than “before”.
    Here’s a link to the project with one frame and 2 grades, the before grade and a new one with a change in key input gain.

    My gut reaction is that the issue is in data levels. During beta, I noticed the majority of the issues I ran into were due to this.

    If its set to auto, change it. And when you render, do a test render with both settings, and try rendering to a couple different codecs (try proresHQ, unc 10 bit yuv, and an RGB codec. When you play back, check your scopes to see if YUV is properly bounded to legal range, or if you;re seeing it go over.

    Well I already tried to change the data from auto to scalled but it doesnt do the trick. I am going back to 8.0.1, my wave is bizarre, the luma and gama controls are acting strange, I only see the result seconds after I touch them.
    I will sure miss the input sizing from the aaf and the dinamics with curves…for now.
