transcode is another thing I have used - if you like the command line (which I doubt)
besides directly using mencoder and/or ffmpeg with custom parameters (found by trial and error)
That was a long time ago …
handbrake is easy to use and gives very good results
I will be testing Handbrake at some different settings to see if it shrinks the files sufficiently.
Default handbrake shrunk 4 Gig to 1.2 Gig but I should be able to do better.
While testing I will use ffmpeg in the konsole as it seems to work well.
I was able to shrink a 1.9 Gig file to approx 450 Meg using this command
