My rendered animation shows a large streak on some of the frames, and not on others. The streak doesn't show in the viewport, only in the final render. Rendered using cycles.

Here's the shadow part of the composite. (Can't be seen over black background)

Here are the composite nodes used. They are the default for motion tracking. I haven't changed them.
