Blackmagic codecs Vegas 9e

First, my appreciation for the work put into Media Express 2.1. Blackmagic listened to my concerns and acted. I couldn't be more pleased.

I am using Sony Vegas 9e. When I render SD or HD AVI with Blackmagic codecs, I get an unintended black level increase. Probably 7.5% NTSC setup. This is a problem since some of my clips already have 7.5% setup.

The exception is when rendering using motion jpeg Blackmagic codec there is no increase in setup.

Is there a setting I'm not aware of?

I've added a post with this same question in the Sony Vegas forum and so far have gotten no takers.

Thanks for any suggestions.

Seeing how the Media Express will only play clips that were either captured by a Blackmagic card (HD Extreme in my case) or clips that are rendered using Blackmagic codecs, the idea of having a codec that can be used to transparently convert an mov, mpeg2, or wmv file to avi Blackmagic is important.

Most of my clips I import to Media Express are avi files. I use Sony Vegas 9e to convert them to avi 4:2:2 Blackmagic so they will be compatible with Media Express 2.1. This is where I see the black level increase. In broadcasting we called this the pedestal, or setup.

I wouldn't expect the hue to change or the color saturation, so why should I accept a black level change? It messes up the contrast and makes everything look washed out.

Again, thank you for passing this on and I look forward to a fix or at least a work around.

Hi Larry,

Are you converting to 8-bit or 10-bit?/ Looks like a gamma issue so I'll get the guys to check it out.

It doesn't matter if it's 8 bit or 10 bit, or SD or HD. Any codec except motion jpeg. And I don't think it's a gamma issue. 7% to 10% setup is added to the video as it is rendered. I have to assume it has to do with NTSC 7.5% setup. I think I need to send "before and after" screen caps of my WFM scope.

Thanks again for your attention to this matter.
