A while after dipping my toe into Fusion, I tried to compare the Planar tracker in Fusion with Mocha which I knew quite well. The conclusion that I came to at the time was that there is a bug in the planar tracker, that prevents the points being represented as x/y co ordinates in the spline graph. When I selected each corner point and converted to x/y co ordinates, as you would with the point tracker, only the x/y points of the corner pin offsets were shown as x/y points in the spline graph but the track remained compound co ordinates. The corner points could be corrected using offsets in the modifiers and each corner pin could be corrected separately in the corner pin controls but the actual track could not be correct.
Here is the test project which includes a moderately chalenging clip.
https://drive.google.com/drive/folders/ ... sp=sharingIt may be an earlier version as I think I had a point tracker corner pin in there as well to compare . To make it a fair fight, I didn't tweak any Mocha settings or adjust the track and didn't pre process the clip.
I didn't adjust the Center x and y of each corner in this comp. That appears to be the only way to correct the track although strickly speaking, it is an offset, not a correction. it's far from perfect, so maybe I will have a go at fixing the track with the centre offset, if no one comes up wit a way of actually correcting the track
As you can see the Hybrid Point mode begins a tantrum around frame 133 and the toys go flying out of the pram at frame 36.
The point mode blows a tyre at frame 137 and goes of the road at 134.
The Mocha track also slipped approx. where the Fusion Hybrid Point mode began to fail but completed the track as did Fusion point mode. Without any tweaking the Mocha track is better and so I haven't really used the Fusion planar tracker again except in basic ideal conditions.
One very annoying trait, I assume it's a bug, is that the corner pin and grid/surface tool will only follow the track in the viewer for one viewing of each keyframe, then it detaches from the track and the corner pin/grid needs to be disabled/ re enabled to get it attached. After one pass it detaches again. This makes it difficult to offset the track. I posted about it at the time but the tumbleweeds must have hidden the post.
I notice, looking again at this comp that deselecting the tracker node and reselecting it also re attaches the corner pin/grid in the viewer, that's got to be a bug.
Maybe there's a answer to this in the tutorial, I haven't seen this one.
