My tracks stop tracking I am almost new with camera tracking and I am working on a small test. But in frame 93 15 of my 18 tracks stop tracking. The rest stops one frame later. The video ends in frame 220. Can someone help me?
Move the tracking point back to the correct position (manually) and continue tracking. If it looses track again, put it on the right track manually again.

If the video is blurry or jumpy the tracking can have problems. Rotating the camera fast will give you a blurry image.
