The whole video frame rate subject would be a great subject for a new one of Dick's tutorials - to cover the subject even moderately well would take something of that length.
In addition to the caution that higher frame rates will really stress your hardware, one other thing to be aware of is that, regardless of the frame rate they operates at, BSR, Camtasia, etc. are "screen capture" programs - and
do just that. You can get very interesting (or strange
) effects from the difference between the display frame rate and the capture rate. My best advice here is to experiment
before you try to "screen capture" a video you really want to keep in a high quality version.
