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).

  • @sds, VLC has some advanced setting which you can try: Tools -> Preferences, then see with Input/Codec tab (like lowering post-processing ,...) and Video tab (try other output mode)

  • @sds, I think this question can counted as off-topic as it more related to VLC that can happen in any Linux distribution (or any OS). What topics can I ask about here?. I don't know if we share same judgment sense. Also I did't flag it, because you could add more information about your case like Ubuntu version/desktop, graphics driver, hardware,...Like that, I may see it as a specific case that needs customized VLC setup or may be even not a problem in VLC itself.

  • @Danatela This question is asking specifically how to convert high quality video to low quality video, not just "how do I convert video to different formats". Not a duplicate.

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. (https://launchpad.net/~stebbins/+archive/handbrake-releases) 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.
