Hello, I've been using chroma keyer a couple of times now and this is the first time this has happened.
For example, it is a vector moving bicycle clip and I used chroma keyer to remove its blue background. I did but there is a rectangle shaped section that has not been chroma keyed. It goes away if I move the clip around in pan/crop however this limits my movements because the moment I move it back, it appears once again.
Please tell me how to completely remove this. Thank you very much

You can layer an additional chromakey effect to target a different color.
You can also adjust the threshold.

If I understand you, it sounds like you have a mask in the filter chain.
It limits the effect to only part of the frame.

The order of fX in Vegas is also extremely important. You need to make sure that any resizing operation or any other fX that might resample the video not be done in the middle of the Vegas key operation.
There are a ton of old posts about Vegas color keying at both the Magix Vegas forum and also several other forums that specialize in Vegas. You'll get a lot more Vegas-specific help at one of those forums.
You can find the Magix Vegas forum, but here is a link to one of the other forums that is very active:
