The 3Dfier 2D to 3D Realtime Transform Filter is On Sale Now

January 26th, 2010 · 26 Comments · 2D to 3D Conversion


If you remember at the beginning of this year I’ve written hat the Taiwanese guys from the company RadiantStar are finally going to start selling the 3Dfier 2D to 3D realtime DirectShow transform filter and they just did that. As previously announced the price for a personal license for the filter is $25 USD and you can order through their website, they are using PayPal as a payment processor so you should not have trouble. You should know that the 3Dfier filter can transform 2D video to stereoscopic 3D in real time with the help of the 3D Vision Stereoscopic Player (version 1.5.2 or newer) or the Stereoscopic Player (version 1.5.4 or above). The filter has been made with the 3D Vision owners in mind although it can work for other stereoscopic 3D setups, but you should have in mind that on such you might not get the same effect. Also be warned that the 2D to 3D video conversion does not provide the same result and is not as good as a true 3D video shot in stereoscopic 3D format.

Converting 2D Videos to 3D using VirtualDub and the AviSynth Script

January 15th, 2010 · 86 Comments · 2D to 3D Conversion


The 2D to 3D Realtime Video Conversion Script for Avisynth v0.3 was designed to be used for realtime conversion, but it can as well be used to get a permanent video converted from 2D to 3D. Sometimes you might just want to have a separate video already converted or your PC might for example not being able to handle 1080p content in real time. An example for converted video is the 1080p Avatar Trailer that you can download from the links below, the video file was just converted with the script so you can see what it is capable of. Just don’t forget that here I’m talking about automated 2D to 3D conversion which can usually provide good results, but they are not as good as what you’ll get from a video shot in Stereoscopic 3D mode. In order to convert videos to 3D with a file output, besides the AivSynth script you’ll also need to download the free video editor VirtualDub along with some codecs that are needed to handle the video and audio output. A good example for that would be Xvid for video and LAME MP3 for audio, but others might as well do… just have in mind that I’m talking about encoding here and not just about being able to decode these formats.


You need to open VirtualDub and then Open as a video file the 2D to 3D AVS script instead of directly opening the video file you’ll be converting, don’t worry, the AviSynt script will do what is needed and will just pass video that VirtualDub can interpret. Then Open the Video menu, make sure that Full Processing mode is selected (on by default) and Open up the Compression menu, where you’ll see a list of compatible codecs installed on your PC. You can choose Xvid MPEG4 Codec and Configure it to use Single pass quality based encoding with a Quantizer of 4 in order to have a good ratio between compression size and image quality.


Recompressing the audio is optional, but you’d need to do it as otherwise the file has PCM audio that just makes the size of the file too big. In this case you need to open the Audio menu, select the Full Processing Mode (here it is not on by default) and choose the Compression option. Again you’ll see a list of installed and supported audio codecs, here MP3 is just fine for Stereo output and you can choose 128Kbps for good enough quality and small file size.

What you need to do now is just save the output file as Avi and the recompression of the video will begin, the time it can take varies depending on a lot of factors for example if you are using a single or multi-core CPU, what it the size and length of the video etc. Here you just need to wait a bit for the processing to finish and after that you’ll be ready to play your converted video file directly in the stereoscopic player without the need to go through the AviSynth script for real-time conversion. So now back to the Full HD 1080p teaser as an example that I’ve converted using my conversion script and VirtualDub, the file is about 170MB…

TriDef 3D Media Player for Video Playback and 2D to 3D Conversion

December 16th, 2009 · 10 Comments · Other S3D Tech


TriDef 3D Media Player is the multimedia photo and video player that you get with Acer Aspre 3D laptops and some other 3D displays, but you can as well buy the TriDef 3D experience software separately. Besides the movie and photo player you also get the TriDef 3D Ignition software that is intended to be used to play games in Stereoscopic 3D mode, but I’ll talk about the gaming part with TriDef software in another post and now lets get back to the Media Player…

The TriDef 3D Media Player is intended to be used to play back stereoscopic 3D movies and pictures, along with normal 2D images and 2D movies that can be converted in real time to 3D. The player practically supports all popular movie and photo containers and formats, including support for the proprietary formats used by the developers of the player DDD – .TriDefMovie, .TriDefPhoto and .TriDefPOPvert. The good thing is that you just need to have the proper DirectShow splitter filter and codec in order to be able to play the video in the player and possibly convert it from 2D to 3D in real time. However prior to the just released today TriDef 3D Media Player version 6.5.5 I had some issues with playing back some video files in MOV, TS and MP4 file containers although the system had the needed support installed, but the good news is that the new version has this fixed. I was a bit disappointed by the fact that the player does not support side by side stereoscopic 3D video and I also had some trouble with above/below, although these should be working and with field sequential video too.

What is quite interesting in this player is the feature to convert in real time 2D videos into stereoscopic 3D, even DVD Video and HD clips. However you should know that the resulting 3D effect depends on a lot of factors and sometimes it can be better and sometimes it can be worse, but there are some things that you should be aware in order to get better results. Using higher resolution and better quality videos does help a lot to provide better conversion results, also using videos with steadier and not too fast paced action usually results in better depth perception. A usual problem for 2D to 3D conversions are the fast paced trailers that do have a lot of action and switch between too much different scenes very quickly, so you might want to avoid these, but it won’t hurt to try them just in case. 3D CG animation movies are usually Ok when converted in stereoscopic 3D, but working with 2D drawn or cell shaded Anime the effect of depth is not that good, but there are still exceptions.


And since there are not a lot of stereoscopic 3D movies and even trailers available having an Ok feature that allows you to convert 2D to 3D videos, however being far from true stereoscopic 3D shot or rendered content is still nice to have. You can also do something else with the help of additional software like Fraps for instance (the video recording framerate should be set to match the source framerate and don’t forget to record audio!) – I mean that you can capture the real time video conversion into an Interlaced video format and then share it with other people that do not have TriDef compatible hardware/software to do this themselves, but still have some sort of Stereoscopic 3D setup. After grabbing the converted video stream with Fraps you should reconvert it to something smaller in size, but have in mind that you should maintain high quality of the video compression in order not to get something with bad quality 3D. An example of what you can achieve with the automatic 2D to 3D conversion with the media player is available here Avatar HD Movie Trailer in Stereoscopic 3D Format. Some videos can convert better, other can convert worse… the results depend on a lot of factors, but I’ll say again that this is still not as good as a true stereoscopic 3D content, so don’t get your hopes too high.

The player does not offer a lot of options and the conversion to 3D is almost completely automatic, however you still have control on two things that can roughly be considered to be equivalent of depth and convergence level (the two controls in the right). This allows you to tweak a bit the results in order to minimize the ghosting in the final video or to improve a bit the stereoscopic 3D effect, but still the rest is done by predefined algorithms. And no matter how good are these algorithms for conversion they are still not perfect and can do mistakes like adding depth where they are not supposed to for instance, although considering they do not require any serious setting up they still manage to do their job quite well and don’t forget that everything is being done in real time.
