Videos can be encoded through the command line, as single commands, or using scripts, or using GUI interface to command line options. This article covers some of the possibile methods.
GUI And Scripted Conversions
Several graphical user interfaces exist to assist with the conversion of video to new formats.
AUR. It uses mencoder and might be a good fit, if want to convert some videos but lack most of the knowledge: While there are (probably?) even easier scripts out there, this one still gives you a lot of choices (most of which you can ignore by pressing enter to use a decent default settings).AUR is a script available in the
AUR is an advanced shell script for encoding DVDs or video files to the H.264 format using the encoding utility MEncoder from MPlayer.
Encoding AVI Videos in Windows and Mac Readable Formats
Use these commands:
opt="vbitrate=2160000:mbd=2:keyint=132:vqblur=1.0:cmp=2:subcmp=2:dia=2:mv0:last_pred=3" mencoder -ovc lavc -lavcopts vcodec=msmpeg4v2:vpass=1:$opt -oac mp3lame -o /dev/null input.avi mencoder -ovc lavc -lavcopts vcodec=msmpeg4v2:vpass=2:$opt -oac mp3lame -o output.avi input.avi
"input.avi" is the AVI you made using Linux utilities, and "output.avi" is the AVI you want to make which will be readable by Windows and Mac users.
(Easy one-liners? I'll think I'll do this Section first, as I did & do have a LOT of misconceptions and I'm sure a lot of people who mostly used windows to convert videos in the past have, too;))
Codecs v.s. Containers
encoder v.s. codec
I want to learn some basics
look (I'm not sure where: links some starting points to look depending on what one needs?)
avi, mkv etc... (max one line description + one link for the most used ones?)
xvid, stuff (..same...?)
Choosing the right stuff
