NAME
       avisplit - split AVI-files into chunks of a maximum size

SYNOPSIS
       avisplit [ -i file -o base [ -s size ] [ -H num ] [ -t s1-s2[,s3-s4,..]
       -c -m -b num -f commentfile ] ] [ -v ]

COPYRIGHT

DESCRIPTION
       avisplit splits a single AVI-file into chunks of size size.
       Each of the created chunks will be an independent file, i.e. it can be
       played without needing any other of the chunk.

OPTIONS
       -i file
	      Specify the filename of the file to split into chunks.

       -o base
	      Specify the base of the output filename(s) avisplit will then
	      split to base-%04d.avi

       -s size
	      Use this option to specify the maximum size (in units of MB) of
	      the chunks avisplit should create. 0 means dechunk, create as
	      many files as possible.

       -H num Create only the first num chunks then exit.

       -t s1-s2[,s3-s4,..]
	      Split the input file based on time/framecode (hh:mm:ss.ms)

       -c     Together with -t. Merge all segments into one AVI-File again
	      instead generating seperate files.

       -m     Together with -t. Force split at upper bondary instead of lower
	      border.

       -b num Specify if avisplit should write an VBR mp3 header into the AVI
	      file. Default is 1 because it does not hurt. num is either 1 or
	      0.

       -f commentfile
	      Read AVI tombstone data for header comments from commentfile.
	      See /docs/avi_comments.txt for a sample.

       -v     Print only version information and exit.

EXAMPLES
       The command

       avisplit -s 700 -i my_file.avi

       will split the file my_file.avi into chunks which's maximum size will
       not exceed 700 MB, i.e. they will fit onto a CD, each.  The created
       chunks will be named my_file.avi-0000, my_file.avi-0001, etc.

       avisplit -i my_file.avi -c -o out.avi -t
       00:10:00-00:11:00,00:13:00-00:14:00

       will grab Minutes 10 to 11 and 13 to 14 from my_file.avi and merge it
       into out.avi

BAD SYNCH
       When you split a file with avisplit and the A/V sync for the first file
       is OK but the sync on all successive files is bad then have a look at
       the output of tcprobe(1) (shortend).

	| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
	| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
	|    10 chunks, 1920000 bytes

       You'll see the AVI file has only 10 Audio chunks but 250 video chunks.
       That means one audio chunk spans several video frames.  avisplit can
       not cut a chunk in half, it only handles complete chunks. If you do,
       say, avisplit -s 20, it is possible that the first file will have 6
       audio chunks and the second one only 4 meaning there is too much audio
       in the first AVI file.

       The solution is to remux the AVI file with
	      transcode -i in.avi -P1 -N 0x1 -y raw -o out.avi
       (of course -N 0x1 is not correct for all AVI files).  Now look at
       tcprobe again

	| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
	| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
	|   250 chunks, 1920000 bytes

       The data in this file is exactly the same (its bit-identical) as it was
       in in.avi; the AVI file was just written in a different way, we do now
       have 250 audio chunks which makes splitting much easier and more accu‐
       rate for avisplit.
