Fusion/Studio 16 - How to smooth bumps in tracking?

PostFri Apr 12, 2019 8:39 pm

Hey all - I've got a bump in an otherwise pretty smooth track in Fusion within Studio 16. I can see in the Spline editor exactly where the bump is; surely there's got to be a way to smooth it! I see options to smooth but that seems to only apply to the tracking between the points themselves. I would be very grateful for some help!

Thanks,

G

Sometimes you can just delete the offending keyframes in the spline editor and the interpolated motion will track close enough.

if you click one of the key frame points in the fusion viewer (tracker node highlighted) a menu will show at the top of the viewer window with tools that will allow you to edit the tracking path manually to your liking. Its Freaking awesome!

For me there are simply bugs in tracker in Fusion. There is a comparison with tracker in Color page which is working like a charm.

The tracker in Fusion behaves very irrationally most of the time.

It has tendency to jump from frame to frame to a point which is DEFINITELY outside it's search region, and it can come back after few frames like nothing happened.

It is very shaky. Look at this example: it looks like every second frame it is tracing some different image. It starts at some moment and later vanishes.

As you see the tracker has to track 3 huge black buttons on white background. And still every second frame is pointing at the trees behind. And as you see on the right there are also triangles where there is one correct frame followed by 2 frames completely off and coming back. For me it is a bug.

This affects both the planar tracker and a "tracker". I have NEVER achieved real success with tracker in Fusion. On the other hand the tracker in "Color" works fine almost every time.
