═══ 1. Help for AVI File Utility ═══

The AVI File Utility is an application that allows you to: 

o View information within the AVI file such as header information, chunk, 
  index, RIFF format, and general statistics associated with the file 
o Merge an audio file with an AVI file 
o Split the AVI file into an audio file and an AVI file (without sound) 
o Change the interleave ratio of audio and video frames 
o Change the skew between the audio and video 
o Add or remove 'Junk' chunks, 'rec' chunks, and an index from the AVI file 
o Create an uncompressed movie from a series of bit maps.

full as the movie is played. 

Changing the interleave ratio can only be performed if the current AVI file 
contains an audio track.

The index of an AVI file is a very valuable piece of the file that is used for 
a variety of tasks, including seeking and scanning.  An AVI file can exist 
without an index, but there are performance penalties when there is no index. 
Once an index has been deleted, the information contained in the index can 
never be recovered.
