When playback of AVI files (containing a video format like XviD or DivX) is stuttering, it in 90% of the files is caused by a poorly or wrongly interleaved file. The issue can be permanently resolved by RE-MUXING the AVI video-files that have this problem
Record audio to MP3 stream and video to MPEG-4 stream from webcam to AVI file using mencoder. Gives floating point exception in some mencoder versions.
Using avidemux to convert multiple files that are in the folder where the command was executed.
It prints myvideo.srt subtitle files in myvideo.avi, saving it in myvideo_subtitled.avi
Record from a webcam, audio using ALSA encoded as MP3, video as MPEG-4.
Rip DVD to YouTube ready AVI file, using MPEG-4 video codec and MP3 audio codec. Resizes to 320x240 and deinterlaces as needed.
That will capture 200 seconds of video at fullscreen 1680x1050 resolution, but scaled down 25 percent, with 15 frames per second.

Reencodes to MPEG-4 DivX output video file from step 1. Audio stream is simply copied. Resizes to 320x240 and deinterlaces as needed. A heading subtitle file is applied as watermark. This heading subtitle file can be a URL.

I've tried all of the screen recorders available for Linux and this is easily the best. xvidcap segfaults; VNC is too much hassle. There are alternatives of this command already here that I am just too lazy to reply to. Messing with the frames per second option, -r, 25 seems to be the best. Any lower and the video will look like a flipbook, if it records at all - -r 10 won't - any faster is the same, oddly enough.
Edit: CLF doesn't like my long command to add audio, so here it is in the description.
goaddaudio()
{
if [ $# != 3 ]; then
echo 'goaddaudio < audio > < src video > < dst video >'
return
fi
f=goaddaudio$RANDOM
ffmpeg -i "$2" &> $f
d=$( grep Duration $f | awk '{print $2}' | tr -d ',' ) &&
rm $f &&
ffmpeg -i "$1" -i "$2" -r 25 -ab 192k -ar 44100 -sameq -t $d "$3"
}
This set of commands will rip a dvd title using a 2 pass mencoder xvid encode. It will provide a great quality rip. It will rip as close to 700MB as possible. (note the bitrate of -700000)
Enjoy!

Takes two input video files and an external audio track and encodes them together to an MPEG-4 DivX output video file with the correct size ready for uploading.
Convert multiple files using avidemux. Version updated (thanks to the guys who helped me giving me hints about how to improve the command). Works with files whose name contains blank characters.
One of the reasons why I love open source: everyone can take something "done" and improve it to make it better! If u have suggestions, please let me know.
Gives MPEG-4/DivX output video file ready for uploading to YouTube from FLV file downloaded from the site and your own subtitle file UTF-8 encoded. No resizing needed. (?)
