NAME
     lavtrans - Convert MJPEG videos to other MJPEG video formats

SYNOPSIS
     lavtrans -o outputfile -f a|q|i|w [-i num] lavfile1 [lavfile2 ... lavfileN]

DESCRIPTION
     lavtrans  can  be	used to convert the recorded videos from one MJPEG "con-
     tainer" format  to another one. It can also be used to split  the	streams,
     or do destructive edits.

     Like  all	the other mjpegtools(1) lavtrans also accept a edit list file in
     place of actual video files. This allows it  to  be  used	to  construct  a
     stand-alone copy of the editted video sequence described in the editlist.

     Note  that  lavtrans can only change the container type of MJPEG video, not
     the format.  As such it is not possible to use it combine streams	of  dif-
     ferent format.

OPTIONS
     lavtrans accepts the following options:

     -f [a|q|m|i|w]
	  Specifies the output format that should be saved.
	    a - output to AVI file
	    q - output to Qicktime file
	    i - output single JPEG images,
	    w - output WAV file (sound only!)

     -i num
	  Convert a single frame to a JPEG file.

     -o outputfile
	  Specifies  the  name	of  the output file If you want as output single
	  JPEG images the output file string must be a valid format string

     filename
	  Multiple filenames as input are acceped,  also  mixing  of  edit  list
	  files and other in video files.

BUGS
     There  seem  to  be problems with the transoding of large Quicktime movies.
     One other thing is that with interlaced movies only one field is extracted.
     So you get pictures with the full horizontal size and half vertical size.
