mencoder, transcode, ffmpeg

The thing to remember is that the file extensions you see on most
videos (.avi, .mov, .ogg, etc.) are indicators of their container
formats and are not reflective of the codecs used within. The
container multiplexes a few data streams, most commonly an audio and a
video track. You could also have other tracks to cover subtitles,
closed captions, translations, commentary, and so on.

So what you ought to be examining is the audio and the video format
used within the container. A lot of stuff you find on the Internet
contain DivX or XviD video with MP3 audio. You can get better audio
quality/compression if you used Vorbis instead. If audio isn't
important, you could cut out that stream altogether.

Hi Sonia,

FFMPEG and FFMPEG Theora integrate with Kino to provide compression.  I use Ogg, 
as the open, format but FFMPEG also does MPEG4 - though I am not sure of the 
licensing on that. You can also run FFMPEG on its own, but it doesn't have a 
graphical interface.


See links from:


If you were making a DVD you would need MPEG2 compression (though this is 
licensed at the encoder).


I recently came across the AMV format on a portable Multimedia Video Player, 
which I documented here:

Mencoder is your Swiss army knife of encoders. It's not on debian by  
default  so it may not be in ubuntu.

[SLUG] compress videos post Kino?

[Sonia Hamilton]

I've been using Kino to record videos of my BJJ training and
competitions [1]. Kino's all working nicely but I've noticed that the
videos (.avi version 2) are large - too large to record to dvd for backup.

What's the canonical way of compressing videos? Any tool people would
recommend?
