The Threshold numbers in CHROMA KEYER– to what do they refer?
Just a question to increase my knowledge and sophistication in using VEGAS 9:
In the CHROMA KEYER FX module, the MIN and MAX Threshold values have numbers in their field boxes.
To what, exactly, do those numbers refer?
Make no mistake, I’ve been happily using those Threshold sliders for weeks now, with success.
But I don’t know exactly what the concrete numbers in the fields stand for… Can understanding those number values increase my sophistication at using the CHROMA KEYER?
Thanks, DAVE

theyre just reference number values in Vegas. In some tools, they have specific value, but in Vegas, they’re merey reference points, IIRC a conversation between me and one of the original engineers, beause I was hoping we’d start seeing greater control ala “Ultra” back in those days.

Thanks, Douglas.
The CHROMA KEYER has worked problem-free for me in nearly every occasion.
The one instance in which I got sketchy results, was when the picture within my color mask was so multi-colored… that literally no color I chose for my surrounding key worked well. )-:
In keying any color, I also removed pixels within my desired picture (because ROYGBIV, and B&W, were all present in my picture).
Perhaps there mnight be a trick to this that I am still unaware of…
Thanks, DAVE

Here’s an excellent tutorial on chroma-keying and the use of thresholds and masking to get a much better effect:
