Hi,

I'm looking for a method to create&nbsp;.WMV movie files with Screen('CreateMovie').&nbsp;

I am creating dynamic stimuli in Psychtoolbox and saving them as movies for presentation in third-party software. The current code saves the movies as .MOV files, but I need to save the movies as .WMV files (.AVI could work but not guaranteed).&nbsp;Is there any way to do that with&nbsp;Screen('CreateMovie') natively?&nbsp;

I did find a toolbox ('mmwrite') that can create .WMV files with Matlab's getframe() function, but I'm not sure how best to integrate it with the Psychtoolbox display.

Thanks,

Laurie
