My question is: the resultant videos seem quite small.
Can you clarify with numbers? Small in resolution or just small in size?
How many pictures are you using for what length of video? Video
compression algorithms work by having a frame of full graphic information,
then transmitting information about how much changed from frame to frame.
If you do not have very many images used for the video, then there will be
many frames in a row which are essentially (or completely) unchanged, so
the resultant video stream will be the equivalent of a picture followed by
a lot of frames with just enough data to indicate the equivalent to "same
as before."
