Quick steps to convert 3D SSIF file to Dubois Anaglyph

There are times when you want to project 3d content on regular TVs (on the go for example) using cheap ($0.99) red-cyan or green-magenta glasses off of ebay etc. To do this you will need to use a good anaglyph algorithm and by far the best publically available one is the Dubois algorithm. See the anaglyph comparison for more info.

I use a simple 3 step process for that:
1) Use SSIFSucka! Beta3 to demux right and left video from the SSIF file(s) and encode the right stream into a full video stream.
2) Adjust the 3d.avs script to the appropriate paths to the Dubois plugin (written by yours truly) and to the left and right mkv video files
3) Use MeGUI to open the script and encode the Dubois anaglyph into a new H.264 video stream.

Prerequisites:
installed Haali splitter, FFDShow Tryouts, and AVISynth
Enjoy

Hi!

You'll find that the capability you've described has been available for several months now, with just two or three clicks from within multiAVCHD...

multiAVCHD does not use the Dubois method and is the reason why I came up with those steps in the first place.

Eric Dubois' least-square projection is a very good optimization of the anaglyph image for a given set of glasses (red-cyan in this case). You can find more info at: Eric's Anaglyph page It is by far the best method that's publically available and documented so that it's easy to implement. The other good methods (such as the one build into the stereoscopic player) are proprietary and no public information is available about them. There are also tons of very poor methods that give you lot's of ghosting or worse retinal rivarly which produces headaches in a lot of people after just a few minutes of watching the content. MultiAVCHD uses one of such poor methods that give me a headache.

Yet another improvement. The plugin was speed up significantly by switching from formulas to lookup tables for converting to/from linear RGB. Link above updated.

Yes. Two major reasons:

1) car/portable entertainment systems/iPads
2) kids (I trust them with $0.99 glasses, not with $100 glasses)

thanks got it!
And why? Cause I don't have an ultra expensive 3d tv and don't plan to buy one!
Actually I have 3d shutter glasses from 10 years ago; and nVidia card. Back then it was only 60hz. I always got ghosting on my analog monitor. If I can find an agp mainboard, i'd like to try it again with modern blurays and modern lcd monitor. This has been around for ages, I don't know why it wasn't popular last time.

Final version. I've tweaked the RGB conversion inside the plugin and preprocessing in the AVS file. I've also added a second AVS file as an example on how to convert side-by-side to anaglyph. Links above updated. Attached are some examples of the final tweak for red-cyan glasses:

Hi dmz01:

I noticed this too late and both Megaupload and Hotfile links are unavailable at present. Would you be so kind to upload or update again elsewhere?. Im very interested.

Thank you very much. Kindest regards.
