Vegas 12, crossfades with color correction
Hi all,
I have a multitrack recording, expanded to seperate tracks. I color corrected all streams (5 in total) so that all cameras look the same and colors are legal (ie 16-235 instead of 0-255). Now a “nice” problem occurs when crossfading between two streams. Is that since the black is now on “16” and not on “0”, when a crossfade appears, it looks as if it adds the blacks together, in the RGB parade you see that the blacks are lifted from 16 to 32 during the crossfade, which of course looks not very nice. Is there a way to create a proper crossfade without adding the blacks.
Anybody ever encountered this? And more over, is there a way to solve it? The color correction FX are all in the “main” fx in the time line, so, not in the clips themselves.
Thank you for your support!

After doing all the color correcting for broadcast, apply the Sony Broadcast filter on the entire project from the video output FX in the preview window area. That’s the safeguard so even if something goes over a bit, the filter will take care of it.

I do it by keeping each camera on a separate track. Fades are done by using a composite level envelope on the upper track. You can only do a simple fade, but the colors are not thrown off by FX processing.

Thank you for your answers. Wat Roger stated is not my exact problem, still a good point though.
@Bob, this could be possible, but will be a LOT of work, since the footage is about 4 hours long, and there are really, really a lot of fades. To be honest I can not get why Vegas behaves this way. It seems to add the color levels. Is there any other way? Argh, sometimes I hate Vegas. Finally happy that my MPEG2 outputs looks good on most HDTV’s, next problem :'(
I don’t know what will happen when I apply the corrections to seperate clips and then crossfade them in one track. It seems to happen with two of five camera’s more noticable then with others. But all in all when the blacklevel is raised (due to brightness, color correction, whatever) that a grey “film” is generated during the crossfade.
