=================================================================
Create mpeg4 encoded avi video container from tga image sequence:
=================================================================

-------------------------------------
# If needed, convert sequence to tga:
-------------------------------------
for f in *.tif ; do convert -verbose $f `basename $f tif`tga; done 

-----------------------------------------------
# Create avi video container from tga sequence:
-----------------------------------------------
ffmpeg -f image2 -sameq -i image.%03d.tga -r 25 output.avi

------
Notes: 
------
# "%03d" is used for a number padding of three (image.123.tga), for
# images with a number padding of four (image.1234.tga), use "%04d".
#
# -f = Force format.
# -i = Input filename(s).
# -sameq = Use same video quality as source (implies VBR).
# -r = Output framerate.

------------------------------------
Adding audio to the video container:
------------------------------------
ffmpeg -i source.avi -i new_audio.wav \
   -vcodec copy -acodec copy \
   -acodec copy \
   destination.avi \
   -newaudio

# Offset the audio start time by HH:MM:SS.frames:

ffmpeg -i source.avi -ss 00:03:04.15 -i new_audio.wav \
   -vcodec copy -acodec copy \
   -acodec copy -t 00:00:36\
   destination.avi \
   -newaudio
