I have a DVD in anaglyph 3D and I am wondering if it is possible to convert the annoying 3D to 2D using AVISynth or AVIDemux?

Unfortunately the director will be releasing the DVD in 3D only :mad:.

P.S. If this is not the right section, please move and I apologize in advance.

Hi! Unfortunately the director will be releasing the DVD in 3D only As far as I know, that may be a first regarding commercial DVDs (3D but NO 2D).

What is the title?

I could be wrong, but there haven't been any announcements yet. So, is there a way to extract the correct color channel without losing much of the quality?

I found a method here but I don't understand the logic completely: http://ricardomonteiro.webs.com/apps/blog/entries/show/18810430-encode-3-d-to-2-d-in-avidemux

This method select view dedicated for particular eye (left or right), discard second view, then one view is resized to full horizontal size.

Compared to stereo sound: only one channel is selected (L or R) then this channel is Mono and second, not used is discarded.

If i understand correctly your question - you are interested in method that re-synthesize video before anaglyph processing (it is not clear to me is source was recorded as 3D or 3D was artificially created from normal video).

Perhaps this thread can be helpful

Thanks for the link. The video used has green-magenta, but the DVD I have is Cyan/Pink.

Also, which method is better one to use? Some of the scripts use both the 2D and 3D version to match the patterns. There are a few posted by different people.
