I use PPro to capture the clip, render the clip and export it as a movie and it is exported as an avi clip using Microsoft DV AVI and DV NTSC. Then I bring it into Ultra2 key out the green screen and render it out using a DV video Encoder format
The clip is 12 min. 22 seconds long. I have tried the clip with and without the green screen keyed out. I have turned the GPU boost on and off in Ultra 2 when rendering. It will crash anywhere form 5 seconds to 4 minutes into the clip. The error message is
