Blender 3D Camera Motion and Object Tracking (High relative speed tracked objects in 3D Scene)


https://i.ytimg.com/vi/Y-OtFQ9x3nI/hqdefault.jpg



Quick tutorial: Example of high relative speed camera/motion and object tracking using:
– Cycles render engine
– Node Picture PNG transparency
– 3 distinct layers (with video masking for front layer)
– Camera moving at 130 Km/H on highway

In this example, there are 3 distinct trackings. One for the road (camera tracking), one for the truck (object tracking), and the last one for the car where the video is done (object tracking). The final scene processes all these 3 trakings at the same time.

  1. how do the markers go of screen without ruining the solve?? i want to focus on one object and pan to another but because the markers go off screen they ruin my solve. please help me cant find any tutorials? thanks

  2. very nice work, definitively helped me out by a lot, though i still have a few questions left:

    1. How did you put together the 3 different tracks? Is it even necessary to seperately track all these things?
    2. How did you composite the first layer (the car)? and
    3. Do i have to change something manually to make the tracking points of my object move or does blender automatically take care of this?

    Would be very cool if you'd answer my question, thanks a lot already.

    EDIT: Ok, i just read the discription, so answer 2 is already answered ^^

  3. What if the video has two different framings changing over time? For
    instance: imagine a shot in which you can see a ball framed and then,
    after a camera moving, you can see a glass of water instead, that was
    placed exactly behind the camera when it was framing the ball. How to
    get a consistent 3D camera tracking? How to achieve the 8 needed
    keyframes for resolution? Please, help.

  4. Great video! I have a question: you used two separate trackings, one for the road, another one for the truck; do you have a tutorial that would explain how to do that? (I am familiar with camera tracking but not with two tracks at the same time)
    Thanks!
