[MPlayer-users] trying to reduce an mpg file's size ...

[Albretch Mueller]

 I have a large (approx. 3.4Gb) mpeg2 video file that a friend produced

 which size I would like to reduce
~
 I have never done that before and I don't seem to be able to find out
how you do that on line. I did search mplayer messages, using , via:
~
 http://archives.free.net.ph/
~
 but I didn't get much out of it. I also posted a similar message at:
rec.video.desktop "trying to reduce an mpg file's size ..."

 How can you reduce this file's size?
~
 I think the only options you have are, reducing:
~
 1) the actual size of the media file, editing the file and leaving
only the parts that are necessary
~
 2) the size of the view window, so less pixels are included in each
image (even though, due to compression, the size reduction won't
certainly be linearly proportional)
~
 3) the number of frames shown per second
~
 4) its resolution, even if its quality will be decreased
~
 After reducing the size of the file I will have to split it smaller,
topical ones.
~
 Is this possible or what is possible using mplayer?
~
 Which other tools will I need?
~
 What would you suggest?

 Thanks
