3DTV Desktop Tool for Use With a 3D HDTV in Side by Side 3D Mode

August 25th, 2011 · 1 Comment · Other S3D Tech


3DTV Desktop is a new tool developed by the Taiwanese company Radiant Star, the one that made the 3Dfier 2D-to-3D DirectShow filter that I’ve already written about here in the blog. Their new tool has nothing to do with autoconversion to 3D however, instead it is targeted to help 3D HDTV users that manually switch to Side by Side 3D mode in order to watch some 3D content from their PC that does not support automatic activation of the 3D mode on the TV set. For example if you open a Side by Side 3D video using a normal video player and want to be able to watch it in 3D on the 3D HDTV that is connected to your computer you need to manually activate the Side by Side 3D mode on the TV, but after the video finishes and you are back on your desktop you will again have to switch to normal mode and then again the next time you wan to watch another 3D video or a 3D photo, or even a game that supports Side by Side output. In order to save you from the need of that constant switching of the TV from the remote control the 3DTV Desktop tool can instead reconfigure your desktop and 2D work environment in a way that it won’t be unusable when you have the TV set in Side by Side mode and it does not display such content. To do that when activated the tool will turn your normal work window into a Side by Side one (squashed) where the actual desktop will be shown in the left side and the right side of the display will be all in white color. This way you will be actually sending Side by Side content to the TV, so your desktop (although it will be shown in 2D) will be visible through the 3D glasses (this will not work well on autostereoscopic 3D displays) and thus saving you from constant switching of the display mode of the 3D HDTV.

Now this may sound as really useful tool for some people and it actually can help quite a lot, but there is some more work needed to be done on it in order to have it even better and more functional, especially considering the fact that it is a commercial product and not a free one. There are also some important requirements that you have to meet in order to have the 3DTV Desktop tool working properly on your computer and doing exactly what it was meant to. There is already an evaluation version available that you can download and test on your computer, it is time limited to 10 minutes of use and to remove the time limit you will have to spend $25 USD for a license, a bit high if you ask me $10 USD for it (the $25 USD price was set there initially by mistake). Be sure that you have the Windows 7 with the Aero interface active as it is required for 3DTV Desktop to work properly, not sure if it will work with Aero on Vista, but it may as well. Another important thing that you should be well aware of is that when at 3DTV Display tool is active there would be 2 cursors on the screen. The thinner one is the one you should look at, and as this is the limitation of the product there are no plans for fixing it. A good thing is that the 3DTV Desktop tool does not need installation, you can just run the executable and it will appear in your system tray, from there you can enable and disable it and you can switch to the Side by Side output “CTRL + 3” and hitting “CTRL + 2” will bring you back in normal output of the display, so there is no need to actually stop the program. When active the 3DTV Desktop tool will monitor the top Window in focus and when it becomes in fullscreen it will automatically switch to normal mode so that you can watch the full screen video in 3D automatically. This is especially useful when you play Side by Side 3D videos from a video player or from a website such as YouTube for example.


         


I did play a bit with the tool and have to mention a few things that I’ve noticed that you should know about. First of all having the right part of the picture sent to the 3D HDTV all in white will make the image from the left part of the Side by Side output seem brighter, but it may also make what is displayed there look distorted. A better solution for that would be to just have the left and right parts (frames) of the Side by Side output show exactly the same image, so you will still see a slightly darker 2D version of your desktop for example. That however can be done at the cost of some extra performance loss, but some things better be done with some performance loss and retaining the best possible quality than not. And talking about quality another thing comes to mind, the halving of the actual resolution of the display and then stretching it again when displayed on the 3D HDTV means some loss in image quality and detail due to the use of image resizing (Side by Side squashed image). And here apparently not very high quality resize algorithm is being used, again probably due to concerns of requiring more resources, however here it is totally justified to sacrifice some performance for better quality. The resize algorithm being used does produce bad quality and loss of more detail in my opinion and after replicating the effect using Bicubic resizing produces better results and retains higher image quality. The algorithm currently being used for resizing currently leads to loss of detail, so that some text with small font size can easily become unreadable while it may still remain readable with Bicubic resize. The two photos above show the original output of the 3DTV Dekstop tool in Side by Side format as well as a simulation of how it will look on a 3D HDTV by resizing the already squashed left frame to full resolution.


         


The two photos above show a simulation of the same thing that the 3DTV Desktop tool does but using Bicubic resize method. On the left you see the Side by Side squashed output, retaining higher quality than what the tool’s resize method does as well as the simulation of how it will look like on a 3D HDTV after being stretched again to full screen. There is huge difference in the readability and usability of text with small font size such as the browser’s menu, the URLs of websites, even the names under the icons of programs on the Desktop for example. The authors of the tool recommend to just scale the font size, a solution that may help, but can also be not so comfortable to the way you are used to working on your computer. So using a better resize algorithm and producing better quality is a must here in order not to hurt the usability for the sake of not sacrificing some performance. And finally the dual cursors, that can be quite annoying, but it seems that the issue cannot be avoided according to the authors of the software. But if you happen to know a way how to do it, then you might as well give them a tip to fix it. Still you are welcome to try the 3DTV Desktop tool, you might find it useful in your way of using your computer with a 3D HDTV as a display instead of a 3D monitor.

Movavi Video Converter 3D for 2D to 3D Video Autoconversion

February 19th, 2011 · 10 Comments · 2D to 3D Conversion


Movavi Video Converter 3D is another commercial software that allows easy 2D to 3D video conversion with Side by Side output as well as multiple anaglyph formats. The software uses the same easy and familiar simple autoconversion techniques relying on frame offsetting and deformation in order to produce the illusion of real depth in a 2D video. The software is commercial, but you can download a free trial version and test it for 30 days, the trial just inserts annoying text over the converted video, but it should not be a problem when just evaluating the software. The software offers multiple video containers and compression formats and has predefined output profiles for multiple mobile devices, but is useful for outputting in anaglyph format only. The Side by Side outputted converted to 3D videos can be opened and watched with the 3D Vision Video Player for example…



You also get GPU accelerated conversion to speed up the process if you have the compatible hardware, like an Nvidia-based GPU and even Multi-GPU configurations are apparently supported for even faster CUDA acceleration. The 2D to 3D conversion process is user controllable through three different sliders: 3D depth, 3D Shift and Perspective, but these don’t have very precise numbering system to give you information on the settings you are using. These setting are the ones that control how the frame gets deformed or the offset for the frames for the left and right eye and unfortunately there are no some recommended settings that can help you get better results, it is only up to you to find the best settings that work for the specific video.

Another thing that I’m not too happy about the software, especially considering it is a commercial solution, is that there is no some sort of scene detection to adjust the left/right frame offsetting used to simulate the Pulfrich effect. As a result when you have scene changes in the video that you’ve converted that are done via cuts and some transition effects you may get uncomfortable feeling when watching the converted video. And considering that the Movavi Video Converter 3D Personal license is priced at $74.99 USD (although there are occasional promotions running for lower prices), the lack of some small, but important features to differentiate the commercial from the freely available 2D to 3D autoconversion solutions is not acceptable. Still, if you are interested in the software, then you are welcome to try it out and share your comments about it below.

MPO Toolbox by Stereoscopy News for Fujifilm FinePix REAL 3D W1

May 18th, 2010 · 2 Comments · Other S3D Tech


The MPO Toolbox is a suite of four small applications solving various issues for owners of the stereoscopic 3D consumer digital camera Fujifilm FinePix REAL 3D W1. The author of the program is Jérôme Leens, Researcher at Université de Liège (ULg) who is distributing it for free. The MPO Toolbox is currently in its first version and is intended to be used under any version of the Microsoft Windows operating system (32 or 64 bit). The software package contains a few very simple to use tools that will help you manage the MPO (Multi-Picture Object) stereo 3D pictures you get when shooting with the Fujifilm 3D camera…

The MPO Toolbox contains four programs that are quite easy to use, you just need to drag and drop a MPO file over the certain tool to get it perform its action. The tool MPO2JPEGS converts one or more MPO files into pairs of left and right JPEG files and MPO2JPS creates single JPS file with the left and right frames in a Side by Side format. The MPO2ANAGLYPH creates anaglyph red-cyan images and the MPO2DUBOIS is an alternative that creates different anaglyph images from MPO with the colors of the original picture being modified in order to reduce the brightness difference between left and right images for the red objects that are difficult to perceive in 3D with the standard anaglyph method.
