How do I convert a high quality video into a low quality one?
The computer is relatively old and underpowered, so video playback of high quality videos is jerky with any player.
How do I convert a high quality video to low quality video?
EDIT:
I tried avconv -fs to limit size and -filter scale=iw/2:ih/2 to resize to 1/2; with output to mp4 and mpg.
All 4 resulting files are not very good: vlc can play the video, but the quality is abysmal on the 1366x768 screen.
The source format is Video: h264 (High), yuv420p, 1920x800, 2030 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc, bitrate: 2127 kb/s (as reported by avconv).

I have no experience of this, however I would assume you should try this. You will have the ability to convert, change quality etc. Not what you're looking for? Try sudo apt-get install transmageddon
Handbrake is a free video converter. There is a PPA on launchpad. () It has options for data rate, audio data rate, resolution, frame-rate, and so on. It may take a little testing to figure out what your system can handle. Use a low data rate, and if needed degrade the resolution down.
Other Info:
480p (Typical DVD Resolution) = 4:3 Standard [640 high × 480 wide] or 16:9 Widescreen [852 high × 480 wide].
800 kbps constant bitrate 2 pass encoding H.264 is where I would start, but if you have a cpu below 1.5ghz then MPEG-4 might be better suited.
