Hello Okichkoatl -
I know we have had some issues in 4.10 regarding the length of the output folder for rendered movies from matinee. Can you try to adjust that output folder to be a smaller file path (character wise), for example something like C:\Temp\Matinee.
See if that clears up your crashing for you. If it does not, can you make sure to submit the crash reporter message and link your Machine ID here. If your crash is not yielding a crash reporter window, please go to the following wiki for instructions and post your windows event viewer:
Thank You
