I am trying to process video shot against a green screen using the Serious Magic Ultra 2 program. The video was captured with a MatroxRTX2 card. It has become a nightmare. I have had all sorts of problems including a successful rendering in Ultra, only to take the clip onto the Premeire timeline, only to discover that Premiere will only render the Ultra .avi file up to the 3rd from the end. There must be some of you who are using the combination with some success. Please Advise.
