Setting the capture framerate below the default can be
useful for generating timelapse movies.
Currently, if you set the framerate below the NTSC/PAL
default, xvidcap will not produce timelapse movies. For
instance, if you set the framerate to 1 fps, on
playback each frame will last for something like one
There is a similar case where something like the
current behavior would be useful: the case of dropped
When frames are dropped, and there is a soundtrack, it
would be good default behavior for the last frame to
"fill in the gap" of the missing frame. The resulting
movie would be jerky, but in theory sound would stay
However, in the case of manually set framerates below
the NTSC/PAL default, this kind of "filling in the gap"
behavior is surely not generally useful. Instead, the
default should be that the captured frame stay a single
frame, generating a timelapse movie.
For instance, if you set the frame rate to 1, you
should get a timelapse movie that speeds up time by a
factor of 25 on PAL and 30 on NTSC. Storage
requirements from captured footage would go way down,
so long sequences could more easily be captured.
