From the man page;

Video Options -b bitrate Set the video bitrate in bit/s (default = 200 kb/s). 2009/4/14 Bruce Kingsbury <zcat(a)zcat.geek.nz>:

When using ffmpeg, the default video bitrate is _insanely_ low, 200kbps or so iIRC. Use -b 800000 (bitrate is in bps not kbps) or thereabouts to get a better quality video.

Hi,

For my study I use a piece of software that displays animated 3d models and which can generate images for each frame of the animation.

I can make these image into an animated gif using ImageMagick's convert or into an mpeg movie using ffmpeg, for use in a ppt presentation.

The mpeg has lots of compression artifacts (I guess because the images are computer generated they have sharp colour gradients). The animated gif looks  great, but is quite a large file.

There must be a way to make an movie that doesn't have the compression artifacts as is done for screencast type movies.

I've done some web searching about this but I'm not sure what I'm looking for. Can anyone suggest a way to do this or some search terms that I could use?

Cheers Glenn
