Ah I got it I have to press some keys to fix it. When I want to record now a video all time hypercam crashes. This happens only with XviD codec.
When I do some motion analysis in solidWorks using XviD everything is rendering fine. Just Hypercam3 is always crashing.
EDIT: Also if I use a predefined profile in XviD (720 for example) Hypercam3 starts recording (without crashing) but never finishes encoding or working so the only thing I can do is killing the Process in the task manager.
Screenrecording with some outdated microsoft codec results in very poor quality and big filesize.
I'm very unhappy with this software.
So I will do some testing on a different Computer at home with this software maybe I can get some better result there.
kind regards
Alex
