High quality video from images by FFMPEG

Gary Steele described how to use ffmpeg to make a video from images by the command:
ffmpeg -r 10 -b 1800 -i %03d.jpg test1800.mp4
(see: http://electron.mit.edu/~gsteele/ffmpeg/)

This command only can output a very low quality video. To make the video better, you can try following command:
ffmpeg -f image2 -i %03d.jpg -r 10 -s w*h test1800.mp4
where w and h are the width and hight of the video image, such as 640*480.

The vim-latexsuit in Ubuntu 11

I failed to install it by apt-get. The version of the vim-latexsuit might be very old in the package source of Ubuntu.
I decide to install the latest version from the vim-latex website. Finally successful following their manual.
