How to split big (video) files and name them?
 

Let's say, there is a home made video called "homevideo", and it is decoded in MPEG4 and wrapped in AVI file format. The size is 1GB, but one wants to split it to two or more pieces.

Now in Gnet, we see all kind of FUBAR file names for these, which simply does not work when one cannot be sure to get all parts of the files from the same host.

Also, lets say homevideo was originally coded as MPEG1, but then it spreaded through p2p network and people converted it to different more compacted formats. One to WMV (*.asf), one to MPEG2 (*.mpg), and one to MPEG4 (*.avi).

How to name the pieces?

Now in Gnet, we see all kind of FUBAR file names for these, which simply does not work when one cannot be sure to get all parts of the files from the same host.

homevideo1.asf
homevideo 2.asf
HomeVideo 3.asf
homevideo A.mpg
homevideo B.mpg
homevideo C.mpg
homevideo 1 of 2.avi
homevideo 2 of 2.avi

So you get one file transffered ok, say "homevideo A.mpg", but cannot find "homevideo B.mpg" after you view the video and notice the rest is missing. Also you didn't know in the start there was also "B" and "C" parts.

You could be happy, if you would then guess the "homevideo 2 of 2.avi" contains also the missing part of the "homevideo", even if it overlaps. But now you just cannot know if it does indeed contain the missing part, even if you would know the whole set would. One can only guess if one sees the file sized of all the splitted parts.

So, I think something have to be done to this problem. I'd like, suggest, there would be some standard how to name the splitted parts of some big media file and somehow "enforce" it.

c/net.com has programs for cutting down the size of a file on there downloads page but the formate it comes out as in end is all up to the program you take and use

Unsplit mpegs
 

I have several movies in mpeg format downloaded from web that are in multiple parts.

Say xx1.mpeg, xx2.mpeg, xx3.mpeg etc.

Is there anyway to get them all back together as a singe file, so that I can play the entire movie at one time.

This is sort of a reverse question of the original post.

In Linux yes: mencoder (MPlayer) or mpgtx
mencoder -ovc lavc -oac mp3lame -o all.avi xx?.mpeg
or
mpgtx -j xx?.mpeg all.mpeg

Mastersplitter is a great splitter/joiner.
BL Joiner (File joiner/ splitter with a GUI) Is also a good choice and it's free.
