How can I get better results when doing motion tracking?
If a tracked element leaves the frame but comes back later in to the shot, it is very important that you track both sections and then join the trackers so that blender understands that is dealing with the same element and not something new. For general tips on motion tracking read: How can I get better results when doing camera motion tracking?
How to pick the best keyframes for motion tracking?
In other words: In the Solve section for A and B select the frame range where you feel that the tracking has been the most accurate and has enough information to solve your scene. If you are unsure, you can let Blender decide what the best part of your shot is by enabling the Keyframe option on the solve tab.
What makes a bad image for motion tracking?
Blurred images, low contrast or flat colors make for bad tracking. Also bad for tracking are repetitive or similar patterns where the tracker might lock to the wrong place from frame to frame. For 3D tracking it’s better if the tracked image that has translation movement and parallax
Why does my shot fail to track properly?
The frames where it failed are marked in red. There are many reasons why your shot fails to track properly making the 3D reconstruction impossible. I’ll address a few. 1- A successful track is determined primarily by the quality of the shot.
How can I pick the best keyframe for my video?
If you are unsure, you can let Blender decide what the best part of your shot is by enabling the Keyframe option on the solve tab. Note that the section of the video clip that will get solved is not limited by the range of keyframes A and B or the auto-selected by blender.
What do you need to know about keyframe animation?
States can be very complex and involve many parameters, like size, shape, color, rotation, brightness, and many more, any of which can change between keyframes. With so many independent parameters under your control, you can create amazingly sophisticated animations and effects with keyframing.
How many tracking points should a camera have?
At least 8 common tracking points. Parallax or information that clearly describes perspective or any spatial transformation. Don’t use sections with a lot of fast motion blur or where the camera remains stationary.
