Workaround for 3D Vision Video Player Not Willing to Play a Video

May 29th, 2010 · 6 Comments · GeForce 3D Vision


By now you should be well aware that the 3D Vision Video Player and the Stereoscopic Player sometimes can behave a bit strange when you try to play some stereo 3D video files, even though you have the right codecs installed and setup in the player. This strange behavior can sometimes be annoying, especially after you mess with the codecs and the player settings in order to fix the issue, but nothing seems to help in resolving the problem. So instead of trying to recompress the video file to more “friendly” formats and thus having to wait more or loose some of the original quality you can try another alternative workaround that may help you play the 3D video…

I’m talking about the use of a simple AviSynth script to warp the video into an AVI compatible stream that should help you play the 3D video file in the 3D Vision Video Player or the Stereoscopic Player. You need to download and install the free AviSynth for this method to work. Then you need to create a text file (name it for example workaround.avs) and enter the following line in it:

DirectShowSource("sailboats-stereo-3d.m2t")

You can either place the AVS file in the same directory as the video file and just change the name of the video, in this example sailboats-stereo-3d.m2t or to enter the full patch to the video file and have the AVS script anywhere you like. Then you just need to open the workaround.avs script in the 3D Vision Video Player or the Stereoscopic Player instead of directly the problematic video file, you need to choose the 3D format and then the video should start playing. Of course this workaround may as well sometimes behave weird and not work, but it doesn’t take time and it won’t hurt to try it out if you are getting trouble with some stereo 3D videos you want to watch.

The 2010 Masters Golf Tournament Broadcasted Online and on TV in 3D

April 4th, 2010 · 6 Comments · Stereo 3D Events


I’m sure that not everyone is fond of Golf as a sport, but this year you might be willing to watch the 2010 Masters Golf Tournament at least for a few hours a day. The reason for that is, because the tournament will be shot in 3D and then broadcasted on a special 3D TV channel and online. For that purpose the golf field will be equipped with multiple 3D cameras placed strategically throughout the course providing views to the audience just like being there, while they’ll be sitting comfortably in their homes. Unfortunately it seems that the live 3D broadcast will be distributed only to those in the United States with 3D-capable television sets or 3D-capable computers. It is still not known if the live online 3D feed will be accessible from outside USA, but if it isn’t people that have access to it will be more than welcome to record the stream and share it with other 3D enthusiasts around the world.

Unfortunately you won’t be able to watch the whole tournament in 3D, but still it should provide you with a good insight on what to expect from the future 3D TV broadcasts of sports and other type of live events. The 3D broadcasts will consist of two hours of live afternoon coverage that will be available each day beginning during Wednesday’s Par 3 Contest on April 7th (3-5 pm EST) and continuing throughout the four Tournament rounds, Thursday, April 8th – Sunday, April 11th (4-6 pm EST on Thursday and Friday and 5-7 pm EST on Saturday and Sunday).

More information on how to watch the live 3D stream online is available at the official website, but you’ll need to stay tuned and check back before the tournament starts for the exact streaming URL. The good news is that if you own a 3D Vision kit and a 120Hz monitor you’ll be able to watch the 3D stream either through the 3D Vision Video Player (the latest version 1.5.5 supports streaming 3D content) or through the Stereoscopic Player (even with other 3D setups… most likely). It seems that the broadcasted 3D TV stream will be in a Side by Side multiplexed 1080i format which is the standard for the new 3D-ready TV broadcasting as defined in the HDMI 1.4 specs. The exact format for the online broadcast still has not been officially announced, but it might as well be 720p to ensure better user experience and less problems with regards to internet speeds, and the format will be Side by Side with 16:9 aspect ratio.
