How To: Upgrade Your 2D Movies to 3D
PrintUnless you’ve been living under a rock for the last year, you know that 3D is this year’s entertainment buzzword. With 3D blockbusters like Avatar scoring megabucks in the theaters, 3D cinema’s jump to the living room is all but a foregone conclusion. But where does that leave all your old 2D files and DVDs?
Thanks to a couple of very cool programs and some clever scripting, there’s hope for them yet. In this article, we’re going to show you how to use AviSynth and VirtualDub, along with a script from the 3D Vision Blog to give any 2D film the 3D treatment.
Convert to 3D with AviSynth
To convert our movies to 3D, we’re going to start with a program called AviSynth, so point your browser at bit.ly/2EO5A2 and download the newest version, then run the installer. You’re probably used to running most new programs after you install them, but don’t bother trying with AviSynth—it doesn’t have a user interface. Instead, it functions as a codec, allowing media viewers such as Windows Media Player to understand AviSynth scripts, in the form of AVS files.
As you may have guessed, we’re going to use one such AVS script to upconvert our 2D file to 3D. It’s not magic—the script simply exploits some common visual cues to take a decent stab at applying a 3D effect to a 2D movie, but it’s certainly better than nothing. The script was written by the author at the 3D Vision Blog, and is available here. Go to the site, copy the script (it’s the first big chunk of code) and paste it into notepad.
Before we can use the script it needs a little customization. First, change the filename at the beginning of the script from “Avatar_Trailer_HD.avi” to the filename of the video you want to upconvert.
Save the script with a .AVS filename extension to the same directory as the video file.
At this point, you’re all set to view your movie in 3D. To do so, simply open a media player that works with AVS scripts (such as Windows Media Player) and tell it to open your freshly created .AVS file. Assuming you’ve done everything right so far, you should see an extra-wide version of your video, with two slightly different frames playing side by side. This is the 3D file, formatted to play with Nvidia’s 3D Vision technology. If you would prefer anaglyph (red/cyan) 3D, for use with a pair of filter glasses, you need to make a quick modification to your script. Comment out (by adding a # to the beginning of the line) the line that says StackHorizontal(f2, f1). Then, uncomment (by removing the #) the line that says # MergeRGB(f2.ShowRed, f1.ShowGreen, f1.ShowBlue).
Save Your 3D Video with VirtualDub
So, we’re looking at our video in 3D. Now we’re done, right? Not quite. AviSynth works in real-time, synthesizing an AVI (get it?) from a source file and a script, frame by frame, as the media player requests those frames. This is hard on your CPU, and means that if you want to view the file on any other computer, you’ll need to install AviSynth first. Instead, we’ll now show you how to permanently save the 3D video to your hard drive.
To save the movie, you’ll need a program called VirtualDub. VirtualDub is a lightweight, open source video editor which is especially good at quickly reencoding videos. Go to the VirtualDub site and download and extract the program.
The next step of the process is to make sure that VirtualDub has the tools it needs to make a high quality copy of the 3D movie. More specifically, it needs codecs—one for video and one for audio. The Xvid MP4 and LAME MP3 codecs are excellent, open source examples of each. If you don’t already have these codecs installed for use with some other media program, you’ll need to get them now. The Xvid codec can be found here, and the LAME codec can be downloaded here. Once you’ve downloaded both, run the installers to registers the Codecs in Windows.
Set VirtualDub to use Xvid by clicking Video -> Compression… and then selecting Xvid MPEG-4 Codec. Set it up for audio by first clicking Audio -> Full processing mode and then clicking Audio -> Compression… and selecting MPEG Layer 3.
Finally, open the .AVS file for your 3D video, and click File -> Save as AVI. Give your file a name, and you’re done.

Making 3D videos out of your normal wedding footage is a cool idea! Hope you had lots of action scenes in it, so 3D effect will be more spectacular on them.
I did the same kind of conversion from regular video of my sister's birthday to 3D kind of blockbuster. Sister hired an event agency to organise her birthday event in a unique way that included racing, dancing, contests and lots of her friends involved. So it had lots of action moments and generally it was a magnificent party! To convert the footage I've shot there from 2D to 3D format I used 3D Video Converter. It's a good software to convert video to anaglyph 3D and I recommend it because of its simplicity and great quality of the output converted video.
Hope this helps,
Gary

You may be able to convert a 2D image or video from a 2D file fomat to a 3D file format, but that will not produce a 3D image. If you're thinking you're seeing a 3D image, this is surely some kind of trick of the mind.
3D works because a "3D camera" is actually two cameras that view any scene from two different points the same way your eyes are spaced apart. When viewed with special glasses, you see a 3D image because these are actually two separate images, one created for each eye. A 2D movie or television show has only one image. The only way to make that image 3D would be to painstakingly alter the image with Photoshop or another image editing program. No script or automated process is going to successfully do this.
If someone whispers something in your right ear, you may faintly hear it with your left ear also, but if you made a recording of that and simply put the sound from your right ear into both ears, it's not stereo. It's just the right ear in both, a duplicate. Stereo only works because sound engineers got the idea to try to make sound positional the same way we use sight for depth perception.
Putting the same image in each eye isn't going to look 3D. This is also why someone with only one eye cannot see 3D films in 3D.
I'm actually very surprised that Meximum PC would bother to publish something so ridiculous, even on the web.
Grab some 3-D comic books with the red-blue or red-green glasses and check out the 3-D effects.

Actually, no matter what method you use to create 3D imagery, what process, or how you arrive at your final 3D image result, as long as you are dealing with a 2D image, to perceive it as 3D involves tricking the brain. You may use expensive equipment, complicated algorithms or simple tricks to render your images. In the end, you still have 2-dimensional images, which lack any real depth, that your brain will interpret as having depth. To make your brain believe that it is seen depth will always, of necessity, involve tricking it.
So the argument is not whether or not the effect you are trying to achieve is a trick of the brain. Rather, it should be how convincingly your chosen method of tricking the brain does the job. Can you perceive space beyond the flat surface that your image is presented on? Are you ducking when the flying object comes your way? Is your brain accepting the trick as plausible? Are you enjoying it all?
If the answer is yes, then the goal has been achieved, no matter how you chose to trick the brain.
If you are satisfied with a simpler, easier, cheaper way of arriving at that goal, then more power to you.
If on the contrary, the simpler methods leave you wanting and you prefer to be more meticulous in arriving at your goal, then by all means, go the extra length.
But in the end, it is all a trick of the mind; it all comes down to tricking the brain.

Animation is a field of art or science that has the capability to impart life and zeal to non living characters. Basically it is based on the phenomenon of persistence of vision that allows the visual illusion of the objects. It is a phenomenon of an eye in which an image continues to appear in one's vision after the exposure to the original image has ceased. 3d Animation Services

In my opnion we need not to shift from 2d into 3d yet because the very other thing that I had noticed is about the involvement of 3D techniques and films in present movies. Most of the new released movies are in 3D and people really like to watch movies that are of crystal clear sound and amazing picture that no other can offer rather 3D movies.

I tried virtualDub, and did all the steps as described above.
But while opening the file in it showed Error: AVI Importer Filter Error: (Unknown)(80040154)
Plz help me out with the problem

3D as a technology is awesome, cause it enables us to watch flat videos/images in three dimensions like we could see them for real as the world around us. 3D TV is already quite popular, so the technology matures and soon we won't need glasses to watch 3D image and won't feel any discomfort accompanied with shutter glasses.That's what I think.
And as for the players or converters I personally use 3D Video Player (http://convert-to-3d.com/3d_player.html), cause I can instantly convert 2D video to 3D while I'm watching the movie. I just click on 3D button and the movie starts to playback in 3D. That's it. However need to put on anaglyph glasses every time to see the effect.

Wannasoft 2D to 3D Video Converter is extremely easy to operate: new technology does not necessarily have to be complicated. The program supports the import of 2D-videos and others in formats Video-DVD, AVI, WMV, MP4, 3GP, MPG and TS, to mention only the most important. The program stores the converted 3D-videos in formats AVI, MPG, MP4 and WMV. It is possible to select from numerous target profiles. For example, the video resolution is automatically adjusted to the parameters for iPad, PlayStation PS3 or Xbox 360. When converting a large number of 2D-videos the batch mode is an option. This mode converts all videos of a list and saves user precious time.

Ok. This might sound crazy but i tried converting lords of the rings 1080p extended version in to 3d. It took me 44 hours to convert one movie. The quality of 3d was very good. But the problem was i got no sound and ofcourse that it took too long.. Can you tell any other program to convert the movies... Coz this one is just so freaking slow.. And thanks for the post... just playing the script does the job a lot of times.. watched dozens of movies that way.. but for hd movies.. we HAVE to convert.. damn..

First of all let me just say that I love the 3D effect produced during stills. I started gaming with NVidia's 3D Vision kit and a 120Hz CRT about a year ago and loved it so much that I recently bought a 3D Ready 720p projector for about $800. The larger 120" projector screen definately produces much more imersive 3D than the CRT while maintaining vivid colors and decent contrast.
I used this method to convert a 720p BluRay rip of Avatar and was blown away by the accuracy of this script in the still scenes, but the fast motion scenes just didn't look right so I opened the AVI in side-by-side mode to see both eye images simultaneously. To my dismay, the motion scenes are obviously out of sync, the left eye is one or two frames ahead of the right eye. The effect is most noticible during scene transitions and running or camera shake sequencenes, but not at all during stills.
As the conversion process took over 8 hours to complete, I haven't had time to play with different settings too much but if anyone has any ideas as to the source of the problem, the AVI script, encoding settings or suggestions on how to fix it please post and I'll give it a shot with the shorter HD trailer.

I hope this 3D thing is just a short-term craze. Unfortunately content providers are pushing it hard, because they know they can charge a premium for it without doing much more work.
The reason is that 3D doesn't work for me. My eyes don't work together. I don't have depth perception normally, so 3D movies can't work. Thankfully Avatar used a polarizing strategy instead of red/cyan, because then at least I can sit there with the dumb glasses to watch a regular 2D movie (though not as bright as it should be). But I still have to wear the dumb glasses. And pay more for the ticket.
I'm not the only person for who 3D doesn't work, I've seen estimates in some articles that range from 10% at the low end to closer to 30%.

I just got my 3D glasses in the mail. the 3d conversion may show the red and cyan but it doesn't work at all with the glasses, the videos dont look 3d at all. i watched a video at "http://www.youtube.com/watch?v=-RKI0mtedZw" which works very well with the glasses. i may need to adjust the settings in the avs file to work. is anyone else having problems with it not looking 3d. fyi, i used the Pixar BURN-E mini film and it doesn't look 3D, i guess i'll try some other videos, if that dont work then i'll be recoding the avs.

If the video on Youtube worked and looked 3D then it is most likely the method you are using to play back your own videos. Check the settings section and look around for the color setting. Try out different color combinations until it works. The most common is red/cyan, but all glasses are different.

This is awesome. Gonna try this later. I haven't tested my 3D Vision with any Stereoscopic 3D movies yet. Although a true S3D movie would be awesome. I think so far only Transformers and the upcoming Avatar on blu-ray will be in full stereoscopic 3D.

The news is not good. When sitting closely to a 3D image on a small screen, a researcher found eye strain and nausea on about 50% of the users with GOOD quality 3D (7-10% in movies). Only NOW are all these 3D Maniac companies sponsoring his research.
The uptake of this will be the, err, upchuck of a lot of 3D wannabe watchers. Sounds like big TVs and long distance seating will be the best way to enjoy it for now. Forget about 3D on the computer screen.
BTW, both ATI and NVidia have a free way to display World of Warcraft, say, in 3D using red/blue glasses ( tried both cards, ATI is a bit better than NVidia). I dare you to try using them for more than 20 minutes though!

The "LAME" link is messed up. It leads to "http://www.maximumpc.com/bit.ly/8VHgfr", it should lead to "bit.ly/8VHgfr". I blame Murphy just like the "Page Not Found!!!" says. I'm just joking, but seriuosly Alex could you fix this, or maybe someone else that has the ability to edit these pages. Also, nice article, I can now watch all of my videos in 3d. But I need to get some 3d glasses. cya

I don't understand how people could have disliked or walked out on Avatar. Not only were the effects and CGI awesome, but the whole story, message, plot was just wonderful! I am a CG artist by hobby, and after doing it for 2 years, I usually really notice what is CG in a movie, and the slight imperfections in some CGI. After watching Avatar I walked away amazed. Barely a flaw in it at all! It was freaking amazing!

Took the wife and kids to see Avatar in 3d and the local IMAX theater and this was our very first ever IMAX visit and after seeing Avatar in 2D and then seeing it in 3D at IMAX I have to say I don't want to ever go to any other theater then IMAX.
Avatar in IMAX 3D is just plain amazing. I was reaching out to grab at the bugs that were buzzing around just inches from my face. It was just wayyyyyyyyyyyyyyyyyy cool.
Also I think people are just taking the story and message way too seriously and personally. Come on it's just a movie. In fact I've seen this movie before. This is like alot of those old Cavalry and Indian wars movies. Dances with Wolves comes to mind when I think of this movie. This is science fiction and nothing else. It's just a story and has nothing to do with real life. Hell it's set in the distant future like 2154 for starters.
People are getting entirely too worked up over the story and plot of this film. It's not anti White. It's just a great story. If you get upset with this story you will probably take Star Wars The Empire Strikes Back personally as well. Get out of here already.
And unfortunately it's people from my party (the republican party) that are getting all upset. But here is one republican that just loves the movie. Hell I even cried at the end. LOL..

Avatar pulled it off well, but if 3D isn't done well its just terrible.

I really hope this 3D craze is just that. 3D gives me an instant headache. When they can do the 3D without the glasses I might try it again, but until then, I'll take 2D video please.
