What is matchmoving, how does it work, and why is it important? How is matchmoving different from the 2D tracking you did in After Effects? Show some interesting examples of matchmoving in action from movies or online videos.
What is matchmoving?
It is a digital
technique that enables the addition of 3d graphics and animation into a
live-action video.
How does it work?
Matchmoving tracks the movement of the camera. It tracks certain features in
the video, like corners, or distinct dark or light spots.
Why is matchmoving important?
Matchmoving
is important to do visual effects work, to usually incorporate 3D elements into
a live-action video.
How is matchmoving different from the 2d tracking did in AE?
The tracking in AE follows a pixel, whereas matchmoving uses the speed of a point and estimates the position of the 3D object(whether its further away from the camera, or nearer to the camera), because things further away from the camera moves slower than things closer to the camera.
