You want to convert Above/Below video to anaglyph, right?

You can use the Stereoscopic Player to play it in realtime this way, without having to convert the video file itself.

An improvement to have everytime audio is:
download this,extract and copy 3 files in avisynth plugins directory
http://www.zshare.net/download/783062297cb4771c/

in script replace
video2d = DirectShowSource(“Avatar_Trailer_HD.avi”)

with
video=FFVideoSource (“Avatar_Trailer_HD.avi”)
audio=FFAudioSource(“Avatar_Trailer_HD.avi”)
video2d = AudioDub(video,audio)

if you have problem in framerate, set original frame rate..for example

video=FFVideoSource (“Avatar_Trailer_HD.avi”, fpsnum=25)
audio=FFAudioSource(“Avatar_Trailer_HD.avi”)
video2d = AudioDub(video,audio)

Guide added to last post. Nobody said anything about this post so I thought it was ok to edit it and point to the current model.

This post is in regard to my previous post in this forum:

I made a test disk to see the parallax between the two images, and at 2 frames difference the picture is too far out, it's two or three pixels out of the recommended 52 pixels.

It's been recommended that the distance between the eyes is 52 pixels, when looking at the 3D picture.
So I made a test disk at 23.976fps, and then set a moving bar moving left to right, between still bars spaced 52 pixels apart.

I then made the 2D image 3D using the conversion process in the first post and counted how many pixels the moving bar was out of the space between the still bars when the other moving bar was neatly between them.

I can post the test pattern I made after, so you can see for yourself. :)
Edit, here is the test patterns:

What this means is I changed the code in the first post and sw kit so only one pixel difference is had if 1fps = 1 pixel difference from previous frame. In simpler terms, it should look pretty without hurting your e yes. I will post some 3D trailers after, I have to encode some first.

Thanks Jeremy, what would actually bring even better results is if we can stop using the 1 frame offset in the visualization process, but still get the needed visual information from the two consecutive frames in order to use it for reconstructing the frame for the other eye. But unfortunately lately I don't have a lot of time to work on that...

26 pixels might be a bit too much separation (especially for low res videos) and that can lead to ghosting in certain scenes.
