Move the Chroma Keyer FIRST in the chain. Or the Chroma Blur first and Chroma Keyer second. Put all the other effects AFTER those two. I did that on your original VEG file and the things that you're seeing totally went away.

Now... you still have the issue of black showing up above her head and below her legs but that's related to where the mask is located. However, just moving those two effects in the chain of effects clears it right up.

Ok so Edward figured it out!

The chromakey should always be first I guess, It was the Brithness and contrast effect that was outlining the mask.

It added some kinda shadowing around the women, I just adjusted the low threshold to 0.30 in the chromakeyer and voila.

Thanks Edward!

I did another test (see JPG) there was no chromakeying involved in this one, I copyed my original video file on to another track (track 1 & track 2 identical) deleted the chromakey and blur effect just for this test, I kept the brightness and contrast + color corrector + sharpen effects on both tracks at exactly the same settings, then I masked only the first track (without any shadowing), we can still see the masking outline, even if you change the order of the effects, the problem was fixed when I deleted all the effects.

So my conclusion to all this is that you have 2 options, 1- when masking you should never add any effects 2- render a file of the masking part without any effects then add it to the timeline and finally add the effects.

Wich to me seems like a major Vegas bug don't you think? by doing that I'd loose time and quality, what I don't understand is why nobody ever talked about this earlyer on this forum?

I did tell you to make sure that Blur/Keying are first. FX are ALWAYS added after a mask or key, regardless of what application you're using. Otherwise, you're asking the mask or key to process the FX, too. That's very hard to do. Color correction, FX, levels...all come after the key, never before. Chromablur and key first in chain (pre) and everything else comes after (post).
Whether it's Vegas, AE, MC, Premiere...It's all the same.
BTW, try to avoid brightness/contrast on video. Use Curves instead. B/C works on the chroma and luma, curves works on Luma and doesn't raise the apparent noise as much.

haha sorry Douglas! I just noticed it.

Thanks for the great advice Douglas, if I use the Curves FX instead of Brithness & Contrast will my mask outline show? (like the JPG in my last post)

As was said, place curves AFTER the key.

I agree that Brightness and Contrast really is NOT what you want to use. The other effects to a much better job. There's an entire discussion on Brightness and Contrast in another thread here from not too long ago. Here it is:
