[BALUG-Talk] Editing 3ivx Video under Linux?

[Joseph Zitt]

I've been digging around the Web for a couple of weeks looking for answers
on this, but haven't found a solution, so I'm asking the Group Mind here:

I have a Flip Video Ultra Camcorder, which saves its videos as 3ivx-encoded
AVI files. While I can play them on my Eee PC running Ubuntu 8.10 using
Totem and mplayer, when I use mencoder or ffmpeg to trim them, the files
lose their sound. I notice, as shown below, that mencoder says that its
audio btrate is missing.

You  can find one of the videos at *http://tinyurl.com/5s8k8e and another at
**http://tinyurl.com/6yy9vr

For each, the original is up, labeled as a Cinepack. Each also has been
converted (by whatever it is that archive.org uses) to a .mp4 file and to an
OGG file, which have the same problem when I try to trim them.

The following is the output of mencoder when I try to trim one of the .mp4
file.

Thanks for any enlightenment...
