Video stabilization

With the Calibration Points tool is it possible to stabilize an almost 2d shaky video?
Maybe rendering a Word View?
Thanks in advance

Yes the world view will give you a stabilized video if calibration points are used to track some known fixed objects. And the latest version of Tracker, released yesterday, has an improved world view that lets you zoom in on areas of interest.

thanks.
Is it possible to render the World View as a video, or export all the frames at once?

That's a really good question and unfortunately the answer is no you cannot render a world view as a video. I should be able to add that feature in a future release, though.  Thanks for asking :-)

Oops, actually Tracker does already have the ability to export a video of a world view. You have to make sure the world view is open in a pane, then choose File|Export|Video Clip. The size of the video is the size of the pane. You can maximize the pane by double-clicking its toolbar.

I just checked to see how the video rendering looked with a zoomed world view and it's not quite right. I'll have to fix that in the next release. In the meantime it works fine if you leave the view unzoomed.  Doug
