I am sorry if it has been asked before, but.

I am capturing a lot of movies with the great feature that new DOSBox has. BUT I am wondering how can I reduce the frame rate the videos are being captured in? As I can see it, it is 70FPS by default, which is quite HUGE. Let's say, I want to reduce it to 30FPS as a default value. Is it possible?

I am asking this because 70FPS is simply a huge waste of video size. And I wasn't able to reduce the FPS of a ready .avi without having the video playback really slow or it being desynched with audio.

Thanks in advance.
