Matte Line Problems with Color Finesse 2

Posted by Eric Goldstein on August 5, 2009 at 5:28 pm

Hi Everybody,

I’m keying some footage (2K from the digital Silicon Imaging Camera). I’m using a first layer to make the key (using Keylight)and using the alpha from that via trackmatte to cut same footage on the layer below to get rid of some problems. On the bottom layer, I’m using Color Finesse 2 for color correction. Above these two layers, I’ve got the same footage that I’m using to roto parts of the imagage that got too much green. I’m using a copy of Color Finesse from the bottom layer – on the top layer to match them. All works well, except the top layer has a black line around each of the mattes. I’ve isolated the problem to Color Finesse. When I turn Color Finesse off in the top layer or apply a different color filter to the top layer – there’s no problem.

Anyone know why this might be happening and if there’s a work around? I’d like to use Color Finesse, but it won’t work if it puts a line around the mattes.

Thanks for your help,

Eric

Hi Dave,

I’m using Color Finesse for final color correction – not to remove spill. The problem is Color Finesse’s interaction with the mattes.

Thanks,

Eric

You are right. PreComping, putting Color Finesse in the precomp, but leaving the Mattes in the main comp worked. Thank you.

By the way, I’ve noticed that the color correction looks great inside of Color Finesse, but loses something when viewed in AE. Any thoughts on how to work around this?

Thanks for your help,

Eric

If you’re seeing a difference like that, we’d love to get screen shots to compare. Send them to support “at” synthetic-ap “dot” com.

Please also include your color management settings in AE. Screen shots of the Project Settings and Footage Interpretation dialogs are the easiest way to capture this info.

Hi Bob,

Thanks for your help. I sent in the files you requested. Unfortunately, you won’t see any difference between the the screen shots in Color Finesse and in AE. Screen shots have to be pasted into Photoshop and Photoshop has the same problem as AE in that images in Color Finesse look different than when in Photoshop.

Thanks,

Eric

Got it! Thanks.

I suspected a color management issue, but you have that turned off in AE. Since you see no difference between the screen shots, but do see a difference when viewing it live, I wonder if it’s a video board-caused difference.

Any chance you have any color management being done by your video card driver? The NVIDIA cards allow some to be done on a per-application difference, so it might be treating AE and CF differently. And doing a screen capture bypasses this processing.

Just an idea that kind of fits the symptoms.
