Short Test Video of BMW 740d in Stereo 3D Format

December 30th, 2010 · 16 Comments · 3D Movies & Videos


The last weekend we did some stereo 3D shots of a test BMW 740d car and I’ve used this opportunity to finally test the native stereoscopic 3D capabilities of the new Sony Vegas Pro 10 video editing software. The video was shot with a dual camera parallel stereoscopic 3D rig using two Sony SR11E HD cameras with interaxial distance of 8 centimeters (about 3.14 inches), then edited with Vegas Pro 10 and the output is in Side by Side format, full 720p resolution. The quality is quite good, however for the next time I’ll need some sort of stabilizing system for the 3D rig as the shaking of the cameras is a bit annoying at times… the whole video was shot with the cameras held in hand. As for using Sony Vegas Pro 10 for stereo 3D video editing, I quite liked the tools and workflow it offers, I quickly got used to it and find it to be the most comfortable complete solution for editing in 3D for now for non-professional users of course, although professionals on a tighter budget may also find it as a good choice. The video is also available on YouTube 3D. And as usual you are welcome to share your comments should you watch it…

    Nice picture quality. However, there are some synchronization issues. How are the cameras synchronized? About camera shaking: http://www.youtube.com/watch?v=kv-yXvERbEs here’s a tutorial how to deshake stereoscopic videos (I haven’t found any English ones).

    I’m using the infrared remote of the cameras, most of the time it works fine for maintaining the sync, but not always… I’m waiting for a wired remote to get better accuracy and functionality.

    For the shaking I’m considering to go for an external mechanical stabilizing system and not a software one. I’ve already tried with a few software solutions, but the end results were not that good, but I’ll also try the Deshaker plugin for VirtualDub, thanks.

    Try prodad mercalli too!
    With wired remote you don’t get perfect syns.
    It’s not depent from that.
    When you switch on the 2 camcorders, at that moment in time the sensor are beginning to work, and if they are not in sync,
    you cannot make it better with a wired record starting.

    And the other end is also true: if the sensors are in sync then it doesnt matter which method you start the recording, even manually with few seconds delay! You can always sync in post to perfect in this case!

    Buy camcorders with lanc connector, so you can measure the difference of signals. Power on/off a few times to get the best settings.

    You should have had turned off the image stabilization to prevent jumps in the video.
    Also the stereo window is about 3 m wide so on my desktop monitor looks miniaturized. Fortunately with my stereoscopic player I can flat the window and view realistic size of your BMW.

    Have a happy New Year.

    Max, the remotes I’m waiting use the LANC port and these camcorders do have it (through AVR connector) and the remotes do have a power on button ;)

    Mathew, the image stabilization from the two camcorders is off, but since I could not perfectly sync the left/right videos for some cuts during the postproduction it might look like the left and right views are “jumping” like with the stabilization on.

    OK,
    it looks good anyway.
    And thank you for posting it.

    Matthew:
    can you write more about this thing?
    “the stereo window is about 3 m wide so on my desktop monitor looks miniaturized. ”

    The visible area in the picture frame from nearest point left to right is 3m, and this looks real only on 3m wide screen?
    And when viewed on a smaller screen, it has to be pushed back, behind the screen? I ask because i have taken “normal size” horses, and many people sayed that it looks like ponys on our 3m wide silverscreen. So, whats the real explanation for this?

    thx,
    and HNY!

    You have to set your camera’s stereoscopic windows the same size as your screen. This way you will see the scene and it’s objects in natural size.
    If on your pictures the horses look like ponys then you need to flat the window in until you see the right size.
    It means that your camera’s stereoscopic window is bigger than your 3m screen.

    You can also use StereoPhoto Maker to adjust the stereo window’s size to fit your screen.

    what’s with videos? I made 3d hd videos with the horses.
    I have to play with the horizontal parallax in post, and push the whole scene back a little?

  • 10 Mathew Orman // Jan 1, 2011 at 17:07

    Yes,
    exactly that will shrink the stereo window.
    But you will loose some resolution.
    Next time make your 3D rig toed-in exactly for 3m wide stereo window and you will never have to change it gain.
    Also you will only loose about 4% resolution due to barrel and keystone corrections in the post.

    My cameras was toed in.
    So what should i care when recording? To the nearest object distance? Or when recording far object i have to zoom in, so when i have a 3m wide screen, objects in far that is 3m wide just fill my screen horizontally? But what if i dont want to zoom in, because of the beauty of wide angle shots?
    This will look always miniaturized on small screen?

    Ah, i think i start to understand it: toe in the cameras exactly so much, where objects overlaps (will be in screen plane) is just 3m wide.

    Is there a plugin (especially for Vegas) for keystone correction?

    cheers!

  • 13 Bloody // Jan 1, 2011 at 19:09

    Vegas 10 Pro has a built in stereo 3D adjustment Video FX that also has a keystone correction option…

    thanks!

  • 15 Mathew Orman // Jan 1, 2011 at 20:06

    Sorry,
    I use Adobe Premiere CS as Vegas 10 has to many bugs.
    Also if you toe-in your rig you will have a fixed stereoscopic window with fixed distance defined by the camera’s view angle.
    That fixed distance should be used to set the best viewing distance in front of you 3m screen.
    Never use zoom as it will distort you perspective and all objects in a scene will look flattened and unnatural in size.

    Have a look at this video for a cheap solution using the so-called “Poor Man’s Camera Stabilizer”, the results are surprisingly good considering its low cost ($14) :

    Here is the site detailling how to construct one yourself : http://14dollarstabilizer.org/
