Realtime 2D to Stereoscopic 3D Conversion from Live TV Source

December 23rd, 2009 · 6 Comments · 2D to 3D Conversion


I’ve already written about the interesting DirectShow 3Dfier filter that is doing quite well with realtime conversion from 2D video to stereoscopic 3D. After playing a bit more with the filter I was able to make it work with live TV feed coming from a TV tuner, but I had to use the Stereoscopic Player instead of Nvidia’s 3D Vision Video Player as only the first one supports the Live Video mode for use with TV tuners and other video capture devices. That said I should also note that I was able to make things work with NVidia’s player too, but with a bit of workaround which is making it a bit harder and not so convenient. If you use VideoLAN (VLC) for capture of the live stream from the TV tuner to a file and then open the video file in 3D Vision Video Player you are still good to go, but with just a little bit of a delay.


And since the Stereoscopic Player is a multipurpouse stereoscopic 3D video player that supports much more than what Nvidia’s player offers, you’ll have to open the File menu and then Settings in order to configure the player to use 3D Vision as a viewing method.


Then you need to go to the Decoder menu and there under the Video Processor category Add the 3Dfy 2D-to-3D Transformer. This is actually the DirectShow 3Dfier filter (download it here) that is going to be used for the realtime 2D to stereoscopic 3D video conversion, unfortunately as I already said this is not a free filter and has some limitations for use. I still haven’t gotten any response from the authors of the filter…


The last thing you need to do is to open the File menu and form there to go to Video Properties in order to setup the incoming video stream. By default it will be a monoscopic source, but after adding the 3Dfier filter it will be converted into a Side by Side format, so you need to change the Format Layout to that mode. This is the last step in the setup process, what is left is only to open the Live Video stream from your TV tuner. After you do that you’ll have some additional settings for the TV tuner that will be available in the File menu, you need to use these in order to select the TV channel and to configure the TV Tuner. You can also just choose the right settings from your TV Tuner software, select the needed channel and the close the software and open the Stereoscopic Player to have the tuner settings already applied. It might not be the most convenient way, but still you get pretty nice results from this realtime 2D to stereoscopic 3D conversion from the live TV feed. As always if you try this, please report your experiences in the comments below…

Impressive Realtime 2D to 3D Video Conversion for 3D Vision

December 21st, 2009 · 30 Comments · 2D to 3D Conversion


I have just found an impressive piece of software, or not actually a standalone software, but a DirectShow filter that can transform normal 2D video files into Stereoscopic 3D in real time and with very good results. I’m talking about the 3Dfier DirectShow filer developed by a Taiwanese company called Radiant Star that in my opinion is the best real time 2D to 3D video conversion solution available so far. That said I’m not meaning that the 3Dfier is absolutely problem free, but still it gives really good results when converting the 2D videos to 3D. You might notice some issues mostly on fast moving and more blurry objects and maybe some jaggy edges on straight lines, but still the depth feeling it quite good having in mind that we actually don’t have the needed depth information as with a true stereoscopic 3D videos. But enough about that, you better try it yourself, the only problem is that the DirectShow filter is not free, but a time limited version (30 days trial, 10 minutes of playback and no depth level control), but maybe Nvidia could license it and provide it free with their future Player software… ;)


For usage of this filter with 3D Vision (the filter can also be used with other S3D systems!) we are going to first need the latest version of Nvidia 3D Vision Video Player and the 3Dfier 2D-3D transform DirectShow filter side-by-side demo v0.2. Download and install them, then run the 3D Vision Video Player, open the File menu, choose Settings… and go to the Decoder panel. From the Preferred Filters menu you need to select the Video Processor and click on the Add button, then select the 3Dfy 2D-to-3D Transformer filter from the from the list of available filters on your system. This is it, now you are done and ready to test the real time 2D to 3D video conversion…


When you try to open a normal 2D video file after you’ve selected to use the 3Dfier DirectShow filter with the 3D Vision Video Player you’ll be asked what is the stereoscopic video format, here you need to choose Side by Side format with the default Aspect Ratio in order for things to work. Have in mind that when the player is in window mode you’ll still see everything in 2D, but when you switch to full screen mode and 3D Vision gets activated you’ll see the filter at work. That is is, you are ready to enjoy your 2D video in automatically converted stereoscopic 3D mode…

For best results you’ll need higher quality, preferably HD videos, but even low quality clips might still look quite well when converted… and you can as well try some DVD Videos you have. One of the issue you’ll face is that you’ll have to remove and then add again the filter in the settings every time you decide to watch 2D or true stereoscopic 3D movies as with the 3Dfier loaded things will get a bit messy when you try to open a stereoscopic video file. Also if you use a Media Player Classic and maybe some other players for normal video playback you might notice that the filter is automatically loaded when you open a movie and you see it side by side. This is something you can manage to fix, but you’ll have to play a bit with the filter settings for the player. And please do not forget to share your experience and comments should you decide to test what was described in this guide.

You can find more information about the filter on the official 3Dfier website…
