Re: [Nuke-users] Tracker averaging?

[Marten Blumen]

Baking the trackers also has the benefit of avoiding the 'recalculating
keyframes' dialog, which can occur when you leave the 'Tracker4' in the
node stream.

Re: [Nuke-users] Tracker averaging?

[Deke Kincaid]

That "recalculating keyframes" only shows up if you have the little
thumbnail previews turned on.  If you turn that off then that dialog
doesn't pop up anymore.

Re: [Nuke-users] Tracker averaging?

[Howard Jones]

One other is you have tracked lots of trackers around one point - to reduce 
noise, and then do the similar for 3 other areas.
Then if you average the 4 groups you can then select them to create a corner 
pin which only allows 4 trackers.

I used to have a tool to do just that but now its much easier.

Re: [Nuke-users] Tracker averaging?

[Daniel Hartlehnert]

Hi Ian,

i am fully aware of the benefit of averaging several Trackers in order for them 
to hopefully cancel out each others noise. I just don't see why you would want 
to create a new averaged tracker. You already have the averaged transform data 
in the Tracker Node transform tab when all individual trackers contribute to it.

For baking out as Deke said, there is the export option (Yes, i used to use 
expressions as well, not necessary anymore though).

I do reckon though, it might be useful if you want to use it elsewhere as 
Howard mentioned. I just cannot imagine a scenario though.

Maybe i am just too dense here, but thanks for everybodies contribution!

Daniel

Re: [Nuke-users] Tracker averaging?

[Ian Northrop]

Hi Daniel,

It can average out the noise that distracts individual tracks, giving you a 
cleaner track.  Think of it like the track equivalent of a temporal blur.  

Best,
Ian

Re: [Nuke-users] Tracker averaging?

[Ian Northrop]

Here is my workflow (though this was more necessary before degraining became so 
good):  If I had a really noise plate, and my tracker was jumping around a lot, 
due to the grain, I would track the same feature a minimum of 3 times with 3 
different trackers (1 node).  because they are started on a different pixel, 
but in the same feature-region, they would all get affected differently by the 
plate's grain, but stay "on-track" to the feature being tracked.  After this, 
you can select all 3, hit "average trackers," and the resulting single tracker 
that Nuke will give you is essentially a much better single tracker, with the 
effects of the grain averaged out.
