3D DVD to 2D

[Island_Dweller]

Hello friends.

I have this DVD "Haunted", which is only available in 3D. And it's really annoying to watch like that.

I was hoping to make a 2D DVD with it. I have already ripped the movie and created a d2v file with DGIndex, as well, as an avisynth script with just MPEG2Source("movie.d2v").

MediaInfo says "2:3 pulldown". So, I used "force film" with DGIndex. I figure it's one less hurdle, not having to ivtc.

But that's the extent of my knowledge. Is it possible to do this and is there some script to make a somewhat decent plain 2D version?

Here is a small sample. http://www.mediafire.com/?b4du4he40b7s0i7

it's the red/blue glasses type of 3d. you aren't going to get rid of that color shifting. it appears there are non-3d versions.

I should have been more specific. It's a Bollywood movie, this one, http://en.wikipedia.org/wiki/Haunted_%E2%80%93_3D .

But I think your assessment still applies. Ah well, it was worth a try.

if it comes out on blu-ray it could be ripped to 2d.

There are ways to "de-anaglyph" a title, but you are battling uphill on this one. Since anaglyph uses color complements on the channels (e.g. Left=R only No Blue No Green, Right=Blue+Green only No Red) there is NO way to completely and exactly restore a FULL COLOR 3D nor 2D version from that.

You can:
1. Restore a full Black & White 2D version, and a nearly full Black & White 3D version (by changing the R channel and/or GB channels to a Luma channel)
2. Get a good Guesstimate at a ful color 2D version by using some of the "de-anaglyph" apps or scripts on the web, which use the G+B channel and then modify the positioning of the R channel to match up to it, then overlay with the G+B.
3. Get a VERY Rough estimate on a full color 3D by doing the "de-anaglyph" on both views. But using the red channel as your positional reference has lots of unintended variability (since you aren't getting a good idea on positioning of the true full color since red is so bandwidth-limited.

Plus, you're battling against MPEG 4:2:0 encoding which has further lost resolution in the color channels.

as aedipuss says, it's best to wait for a 2D version, or a true BD3D version (which, being full color and 2D-compatible, is alot easier to work with/from.

Thanks Scott. You gave me a lot of information to work with, but I really just want to have a somewhat decent 2D copy of it. I suppose #2 from your list is what I'm after. Do you happen to have a sample script?

There's this:

and this:

(although that is geared toward green/magenta, instead of the more common red/cyan - but you can modify the channel assignments to fit)

There may be a few other variations, but that's a good start...
