We used the program for all of our greenscreen effects in MB3K. In the trailer, there are a few shots that use the effect.
It's actually quite effective, and I would highly recommend it as a cheap, first keying program. It doesn't do everything as well as it says as far as using a "bad greenscreen" though. If you have properly lit footage, Chromanator does a great job.
For an "amatuer level program", I would say it's cream of the crop. The demo might not do it justice. If you want to see what we did with it, check out the Macbeth trailer (
www.superguncinema.com/mb3k). The shots that use a greenscreen are:
-the jet pilot cockpit shot
-the newscaster
-the parachuting shot
-the shot of multiple zombie-Banquos turning around
We used thier other program, AlamDV2 for all of our effects, as well.
I think, for the price, Chromanator is a great program for cheap, effective greenscreens.
