    $40 for FFMPEG / Mencoder to create small size MP4 (Command Line)

    I came upon a site which have lets say an original AVI file about 150mb, that site was able to convert it to 20-30MB and work with online streaming.

    What i want is the COMMAND LINE to type in COMMAND PROMPT. TAKE NOTE: I DON"T NEED ANY PROGRAM, i just want the command line for MENCODER or FFMPEG to create same output and compression as the one below. The file size of the file need to be greatly reduce yet in a good quality .


    PM me the solution & Your paypal detail. I will announce when job close, else it will be open to you guys.

    Hello,

    We can do this through the linux console, using the command
    " ffmpeg -i abc.avi abc.mp4 "

    i converted sample avi file to bitrates you posted but quality is awful.
    anyway command is:
    it converted 360mb avi to 40mb mp4 but as i said quality sucks.
    for me best result was with following command:
    which gave me 170mb output out of 360mb input file and almost the same quality.

    imho you need to play around with different bitrates to find one that fits your needs
    it should be like: file size / duration = totalbitrate and total bitrate - audio bitrate = video bitrate

    btw You might need to upload libx264-medium.ffpreset libx264-medium_firstpass.ffpreset to /usr/share/ffmpeg/ directory.
    You can get it for example from here:
    http://trac.assembla.com/oitjp_turb...e/ffmpeg/share/ffmpeg/libx264-medium.ffpreset
    http://bencos.googlecode.com/svn-history/r156/trunk/out/presets/libx264-medium_firstpass.ffpreset
