How to Demux avi with multiple video streams?

[wpw007]

Guys, fascinating thread. However, I could really do with some help in reverse, i.e. I have a Fuji W3 camera that shoots the separate dual stream 3D AVI files but I also have other side-by-side 'normaly' AVIs / MP4s etc. As I have a glasses free Fuji V3 media player, I'd like to be able to render / save the side-by-sides as the dual stream separate AVI format as it's the only format the media play recognises. I've never used GraphStudio before, but am familiar with After Effects. Can anyone give me an 'idiots guide' step by step on how to do this pls?
Thnx in advance.

As an owner of the W3, I can tell you that Finepix Studio, while it does work, is basically a klunky newbie toy. Any real work that needs to be done, ought to be done via better tools: StereoMovieMaker, GraphStudio, AVISynth, Stereoscopic Player, and true 3D-aware NLEs and Compositors (Vegas Pro, AE, Edius, PowerDirector, etc).

Plus, don't graverob. I'm not sure that this counts as one of those exceptions.

This method also helped me edit some 2 channel video from my BlackSys CF100 automotive DVR.

Not many tools can deal with the dual video streams. Here's a graph from GraphStudio that will split the video into two AVI files:

On the left is the File Source (Async.) filter. The output from that is routed to the AVI Splitter. The left video and both audio channels are routed to an AVI Mux filter, the right video output to a second AVI Mux filter. The two Mux filters are routed to separate File Writer filters, left.avi and right.avi. After "playing" this graph you will get two AVI files. Only the left one will have audio.

Here's an AviSynth filter that will create a color anaglyph:

left=AVISource("left.avi").ConvertToRGB()
right=AVISource("right.avi").ConvertToRGB()

red=ShowRed(left)
green=ShowGreen(right)
blue=ShowBlue(right)

MergeRGB(red,green,blue)
