| Sorry, this is a Pr issue. I'm posting here because I wonder why it's not an Ae issue. Let me explain. I'm getting these little crosses in zero black areas using Magic Bullet Looks on an Adjustment Layer. Here's a screen grab: http://jamesphilipcurtis.com/public/Screen%20Shot%202012-08-08%20at%209.54.15%20AM.png I'm getting this in Pr 601, MacPro3,1, 10.7.4, Quadro 4000. The footage is ProRes4444 recorded from Arri+Cinedeck This is some interaction with the Pr Levels effect on each clip, where I've taken the linear footage, and expanded the black (and white) levels to 0-100. Turning off GPU in Looks prefs gets rid of them, but then rendering takes 10x as long. I pasted my timeline from Pr into Ae. Applied MBL to an Adjustment Layer, and the problem does not repeat in Ae. I deleted the first instance of MBL in Pr, and applied a fresh Looks setting. The crosses come back, but much tinier, even with no changes made in the MBL GUI. I tried trashing Looks prefs, Pr prefs, reboot, reinstalled CUDA and nVidia card drivers. This only started recently after using Looks with the same setup ever since CS6 came out. I have discovered a workaround, but it's not perfect. If I set each instance of the (RGB) Black Output Level on the source clips Levels Effect to 1 instead of 0, the crosses go away. I surmise this is perhaps a sub-black warning in Looks? I'm wondering why I haven't seen it before, and why I don't see it in Ae, even if I force the black in the source clip to less than zero, followed by MBL. I believe that Pr doesn't allow sub-black, but Ae does. This may be why I can't repeat this issue in Ae. Thanks, Jim C. . |
