Imagemagick can
`convert`

multiple-image files (like PPM) to the much
more compact MPEG format, but it
requires `mpeg2encode`

, which is available in the mpeg2vidcodec
package. As an example of the compactness, the 85M
`vorticity.ppm`

Kármán vortex street animation produced by Gerris, becomes 1.9M after

$ convert vorticity.{ppm,mpg}
