I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. Nice tutorial. Didn't know the process of camera tracking. Is nice to have a tutorial to integrate this technique into Blender.

    Great work young dude....


  2. Pretty well done. I thought motion tracking was complicated but apparently not.

    Anyone want to buy me a video camera? Whoa, calm down! Line up over here please.

    I wish.

  3. Really nice, but there is no free version of Voodoo for MacOS X ... hmm only VooCat for EUR 117,-- but if I have to pay I would take syntheyes ...

  4. Syntheyes is the best bang for the buck you can get. It is widely used in the professional industry, next to Boujou, PFTrack, ...

  5. I have been trying to get my hands on a copy of the Voodo software for a PC for over a year now. I have tryied from so many different computer, but they all fail to download. It looks like they have put a password on there ftp site. Sould sombody be so kind and send me a copy of it or a PC. Depending on it's size it might be best use the fre ftp site of Thanks.

  6. This makes me want to try Voodoo again. If it doesn't crash on me... again...

    Maybe I was trying to work on something he could not work with...

    Thanks for the tutorial :)

  7. I've tried this a couple of times with basic success.

    I do have a workflow question here: The cubes position was done by trying. When you look close enough you can see that it is hoovering off over the left side of the book.

    When you open the Track in Blender what would be the best way to rebuild and align the scene first (using very basic shapes), and then add objects that wont hoover and align perfectly ?

    Say I add a plane that resembles the desktop in the vid. Are there any "helper-points" to get the right angle, distance and size ? If you mess up with the "distance from the camera" adding objects will be quite frustrating.

    I think it could help if you add reference object with well known dimensions and try to get this right first. Or maybe you start each shot by adding some type of ruler, track this a few frames and use this as a reference. I guess you could remove it after a few second since you got that one ref-object defining the 3D-Position of the basic scene ?!?

    This is not a voodoo specific question. Any ideas ?

    Regards, Christian

  8. Excellent tute! One suggestion to make your presentation quite professional, eliminate the 'ums' from your narrative. Again, very good tutorial, thanks.

  9. Since you were using NTSC footage, you could have just clicked the NTSC preset button instead of messing with pixel aspect ratios in Blender... And NTSC is lower fields first, not upper.

      • actually i found an ever better voodoo script importer that works better then the link fixer . I don't know why you feel like being a jerk about it , but the fixer was useful in that it helped where this tutorial failed .

        • Sorry, I didn't intend the comment to be snarky - I misunderstood the way the script updater worked and only saw Python comments line in the text. I wonder why they don't just offer the updated script instead?

          Would you mind sharing the other voodoo import script with us?
