-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.

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

| 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

| 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 accurate for avisplit.
