How can I watch a 3D SBS video?

[Big-Louis-1971]

People I have some 3d SBS videos and I was wondering if I can watch it in my 2D HDTV with the help of active shutter glasses. If not, please tell me the correct way to do it. Thanks in advance.

Trash them. Your illegal vids are of no use without a 3d tv.

??You have active shutter glasses, but NO 3DTV?? What, did you just pick up some glasses off of ebay?

If you have a 2D TV, you can watch SbS videos with any of the 3DBD-compatible disc media player softwares (Cyberlink PowerDVD, Corel WinDVD, Arcsoft TMT), or you can use one the the General-purpose 3D media players (nVidia nVision, Stereoscopic Player, StereoMoviePlayer).

ALL of those will convert SbS to Anaglyph during playback (since IIRC, you've already stated you have anaglyph glasses).

If you actually have Active shutter glasses with an old-school Active Shutter xmitter (one that does Interlaced at 30Fps per eye) you could use that with a 2D TV - as long as your TV doesn't force deinterlace it. So, clearly, old CRT-type TVs would work, but most new HDTVs wouldn't (because you can't usually turn off deinterlacing and those TVs are primarily progressive devices). Then, you should use Stereoscopic Player or StereoMoviePlayer and it should modify it correctly for the xmitter.

BTW, if what you meant to do was watch those 3D SbS files IN 2D, those same players can re-format the layout to just show 1 view (2D), sometimes called "Monoscopic".

You could use avisynth to stretch the video horizontally by 2x and place it in a 16:9 frame and use the cross eyed method to watch in 3D.

How can I do that? Can you point me to a tutorial?

Here's a sample SbS-to-Xeye script (obviously, you must fill in your own source file, and that might require different parameters):

sbssource=directshowsource("\\Mediaserver\Video\VideoScott\Public\Stereo3D\_Side-by-side\test-028.mkv")
lefthalf=crop(sbssource,0,0,sbssource.width/2,0)
doublewideleft=lanczosresize(lefthalf,(lefthalf.width)*2,lefthalf.height)
righthalf=crop(sbssource,sbssource.width/2,0,sbssource.width/2,0)
doublewideright=lanczosresize(righthalf,(righthalf.width)*2,righthalf.height)
crosseyedcomposite=stackhorizontal(doublewideright,doublewideleft)
return(crosseyedcomposite)

If you are just starting out with AVISynth, though, it CAN be daunting!

This script would then be opened in a Media player app that can accept AVS scripts, and would be run in "full screen" mode during playback.
