For all the many years I've been using vMix, the keyer remains my primary point of pain. In the best case scenario, the most precisely lit screen, low noise on the image, etc... you still get a one-ish pixel white halo. If you push the filter to get rid of the halo, and colors that shouldn't be transparent become transparent. "preset 2" is a good example of a bad key: Sure, the halo goes away, but the filter is pushed so far you lose the detail, mangle colors, and create semi-transparencies in yellows and blues where none should exist.

Antialiasing sorta kinda helps, but nothing above low... and without a choke it can be counterproductive.


Can we get a simple matte choker and a matte view? "choke, edge width and aa spread" in subpixel incr. is really all it would need to help immensely.

If not that, could we at least get some control of the color of the transition zone (aka, the halo)? A white halo is fine on a bright background, it would look much better as a dark halo, or a color that could be tuned to the background.


Please, any kind of edge control or key layering would help.



PS... A multivalue or vector keyer would be even better, but don't spend 5 years doing that instead of spending 5 days doing a matte choker... do both :)


Thanks
