Tip #693: 3 Quick Motion Tracking Tips

Camera moves – Shutter speed – Depth-of-Field
Ever have trouble getting good motion tracks for your visuals? The problem usually lies in the camera settings!
Here are three simple steps to follow to improve the quality of the source footage for a motion track:
- Make sure camera moves are not too complex and pay attention to parallax.
- Shutter speed heavily affects motion blur. Higher shutter speeds minimize motion blur and improve the image quality of visual effects. The recommendation is 1/200th or faster.
- Decrease aperture to increase the depth of field. This helps the computer track contrast points.
um “pay attention to parallax” – means what exactly?
bit vague…

Thanks for the link, we now know what a Paralax effect is, but, we still don’t know on “what” of the paralax effect we must pay attention?
Ivan:
Paralax is how objects move when viewed with two eyes – it helps determine foreground vs. background. This tip simply says avoid doing a big camera move when, as you move, the relationship of the different elements in the frame don’t change position.
