After successfully tracking a relatively short clip with the planar tracker, Fu9 crashed while I was scrubbing back and forth to check my track with a foreground element (text).

Not enough information to reproduce or its a bug that only occurs sporadically.

I've tried to reproduce this in Windows 7 and was unable. These are the steps I followed:

1) start Fusion
2) add a Loader to bring in some footage
3) add a PlanarTracker tool and view it in the left view
4) select the region to track and track it
5) connect in an additional Loader to the PlanarTracker's cornerpin input
5) scrub the timeline to try to provoke a crash

I was unsure which mode to put the PlanarTracker in, so I tried scrubbing the timeline in all 4 modes for about a minute in each mode (Track, Steady, CornerPin, Stabilize).

Thanks for trying it on your system.
The steps are exactly like mine, and I scrubbed in Corner Pin mode. Only difference: I'm on a Mac.

I tried to reproduce this with Fusion 9.0 build 13 on El Capitan. No luck. I tried variations with AutoProxy on/off and HiQ on/off. I tried scrubbing the timeline with/without caching the PlanarTracker's output beforehand. There must be some condition that I'm not hitting or something I'm doing differently, if we can figure out how to reproduce this, then it can be fixed.

Thanks for testing so carefully. I'll conduct further tests too.

Edit:
With further testing, I couldn't reproduce the issue. I may have to write it off as a temporary hiccup.

P.S. The planar tracker is pretty impressive and may replace Mocha in most situations.

It could be a crash related to something else Fusion was doing at the time and not PlanarTracker. It could also be just some weird timing crash where you need to get the timing exactly right or it doesn't occur. If you happen on a reproducible test case, please let us know.

Thanks for reporting!

Sure, as soon as it rears his ugly head again!
