Fxguidetv Interview with John Knoll About Star Wars 3D Conversion

March 7th, 2012 · 2 Comments · 2D to 3D Conversion


Here is an interesting interview from fxguidetv with John Knoll, visual effects supervisor at Industrial Light & Magic (ILM) who was a VFX supervisor for Star Wars: Episode 1 and has also supervised the stereoscopic 3D conversion of Star Wars: Episode 1 – The Phantom Menace. In this interview John Knoll comments on his approach to the stereo budget, floating windows, parallel vs. converged, shooting stereo vs. post-converting and gives his views on how other studios are solving these complex stereo problems. It is a long and interesting interview not covering only the 3D version of Star Wars, but the use of stereoscopic 3D technology in movies in general talking about other good 3D movie examples and their approach to the use of 3D including Avatar and How to Train Your Dragon, so definitely worth watching, regardless if you’ve liked the conversion to 3D of the movie or not.

Disney and Pixar to Convert to 3D More Of Their Classic Animations

October 4th, 2011 · 9 Comments · 2D to 3D Conversion


The big success that the re-release in movie theaters of Disney’s classic animation The Lion King in 3D (converted from the 2D original to 3D), about 80 million USD in the US box office so far, the company appears to have decided to have more of its classic animations converted to 3D for the big screen as well. Disney has announced that the following titles from Walt Disney and Pixar Animation Studios will be released converted in 3D in 2012 and 2013:

– Beauty and the Beast – January 13, 2012
– Finding Nemo – September 14, 2012
– Monsters, Inc. – January 18, 2013 (Monsters University, a prequel to the original film, arrives in theaters in Disney Digital 3D on June 21, 2013)
– The Little Mermaid – September 13, 2013

Now if this is a good move or not is still yet to be seen, but there will be a lot of controversy surrounding these releases as they will be 2D to 3D conversions. Disney’s decision is apparently driven by the good profit that they have realized with the Lion King 3D conversion, but it is still unclear if other of their classic and more recent animations will also manage to attract so much attention. Starting today The Lion King is already available on Blu-ray 3D and the same goest for the movie Beauty and the Beast also already converted and available on Blu-ray 3D media. And since the 3D conversion for the Beauty and the Beast is already ready the January 13th release date for the big screen shouldn’t be a problem. There is also quite some time until September next year for a proper conversion of Finding Nemo, so Disney is apparently not rushing things just to make some quick profit, but should instead take their time to do good conversion to 3D. I’ve already seen the 3D conversion of the Lion King and Beauty and the Beast and can say that is was done quite well, although far from perfect, and without major issues to bother the normal viewer. I’ve watched both movies converted in 3D and will watch the other conversions from Disney as well even if it is just out of curiosity, would you?

YouTube Now Offers 2D to 3D Video Conversion Functionality

September 25th, 2011 · 5 Comments · 2D to 3D Conversion


YouTube has announced new interesting functionality for the stereo 3D community, namely the ability to convert the 2D videos you have uploaded into 3D format automatically with just a few clicks. This is of course a beta functionality and as with other autoconversion solutions it might not work perfect with all kinds of videos, so you should try with different videos and see what works best for you. You should also be aware that the level of quality that the 2D to 3D conversion YouTube offers will not be as good as properly shot video with a 3D camera. But since still not a lot of people do have 3D-capable recording hardware YouTube’s 2D to 3D conversion feature probably is a way to help push more 3D content. The embedded video above is something I’ve shot with a 2D camera and converted into 3D using the YouTube 2D to 3D conversion feature. Have in mind that when you request a 2D to 3D conversion your original 2D video will remain and it will get a 3D button available in the YouTube player. And when you hover your mouse over the 3D button it will say “Converted from 3D”, a good way to differentiate 3D videos uploaded as such as converted to 3D videos, but probably not good enough to quickly differentiate them. The conversion process currently can take a while, especially if you have a longer video file that you want to see converted to 3D, so be patient…



And now for a quick guide on how to use the 2D to 3D conversion feature of YouTube. First off you need to login to your YouTube account and open the video you want to convert into 3D from the list of videos you’ve uploaded. You need to be on the page with the video details that you normally open when you are watching a video on YouTube, not on the page with all your uploads listed in your account. What you need to do now is click on the “Edit info” button that you will see right below the YouTube logo (the first button), make sure you click this one and not the Edit video button.



after clicking the “Edit info” button you will see a new menu shown at the position you’ve had the button you’ve just clicked. Now you have on the “3D Video” button in order to tell YouTube you are going to be working with a 3D video, this is also the new way of telling YouTube that a video you have uploaded is in 3D format and not using the yt3d tag anymore. For the 2D to 3D conversion feature to appear you need to select the “Single image in frame (normal video)”, if you select the 2 images in the same frame it would mean that a video you’ve uploaded is already in 3D format and you just need to let YouTube know what is the right format.



Now what is left to do is click on the tick the box in front of the “Enable 3D conversion for this video” and then click on the “Save Changes” button. It is very important that you save the changes, because unless you do that the conversion to 3D of the video will not start. After clicking the Save button you will see a message that the conversion has started and it will take a while, and it does take a while, especially for longer videos, so you can take your time and do something else and not stay on the YouTube page constantly refreshing. It is good idea to start with shorter videos at first just to experiment and not wait that much time for the conversion to finish just to see that the 3D effect isn’t that good after the conversion.

Have in mind that while YouTube’s 2D to 3D conversion feature does quite good it is not a complete and recommended replacement for a standalone software that does a 2D to 3D conversions, especially if you want to convert long and high-resolution videos or even movies. When you upload a video to YouTube it gets recompressed to further reduce size and there is some loss of quality and 2D to 3D autoconversion solutions are sensitive to image quality. So if you try to autoconvert a lower resolution and not very good quality video to 3D due to the processing by YouTube after the upload and in the 3D conversion process (you have no control whatsoever on that at the moment) the resulting clip may be a total disappointment. And with all that said, you should also be well aware of the fact that although autoconversion solutions making 3D video from a 2D source may seem quite convincing at times it is still inferior to video shot with a real 3D hardware. So don’t go converting 2D to 3D video just so that you can complain it isn’t very good, we all know that very well already…
