AE CC 2017 – Smooth Tracking Motion path
Hallo everybody,
I did many tracking (Tracking Motion type) and sometimes it could be very useful to be able to smooth the tracking Motion pat. I tried a couple of strategies but without big results…:
1. I tried to smooth the original Motion Tracker using Graph editor using some interpolate types but I can’t see any differences…
2. I tried also to smooth the Null layer (Edit target) but is the same. Probably I don’t know which is the right way…
There is a way to do it correctly? (In Mocha, Nuke, Syntheyes there is a specific command to smooth a tracking path…).
Thanks in advantage for you help!

Hi David,
many thanks for your replay, but the question was not if I did a bad or a great tracking…, the question was “How to Smooth Tracking Motion path”…
I’m used to working with Mocha Pro and Syntheyes and I have e very different concept about what is “a good job”.
Anyway, I tracked this video using Track Motion with different Options:
The best result was tracking only with one tracker. But smoothing the path could be improve tracking…

I forgot to say that what I tracked was already in the first post image…

Maybe could be useful: I noticed that the “Attach point” tends to lose the central position, in other words he does not remain at the center of the “Feature area” but tends to decentralize and therefore, even if the tracking path is fluid (a good job …), in reality is the “Attach point” bobbing up and down. The problem is that we link the Null (Edit target) – to which we then link a text or a graphic – to the Attach point “and not to the centre of the Tracker (Feature Area)! So, if the attach Pint bobbing, same thing happens at the Null …

Go into the motion track, and delete some of the tracked keyframes–specifically the ones where an undesirable jump occurs. After Effects will interpolate the motion between them, smoothly. I do this all the time when I get a little bit of undesirable jitter in a point track.

Great Blaise, this is a gut suggestion! Many thanks!

There’s a preset expression already built in that will smooth that out… alt click the position stopwatch to enable expressions, go into the little arrow, property -> smooth.

Hi Cassius,
I read about that but forgot to try it. I make it now!Many thanks!
