AFX Tracking

[scrimski]

Not possible in AE. As said, you need a 3d tracking software.

Aye, you'll have to do what Scrimski says.

My advice is to download something like the Syntheyes demo (http://www.ssontech.com/regis.htm), press the magic "full auto" button, and see how well it solves the track. The demo won't allow you to export the data to a third-party application, but it will give you an impression of what you have to do to track the shot.

Good luck,

Thanks a lot scrimski, Jonas


I thought as much, but needed to be 100% certain. As it means spending more money, or the studios. I have played with the tracking tools within AFX and had some ok results but only on very static shots or where the camera has been locked off.



Could I ask where you guys/gals have used the tracking functions within AFX for projects?



Thank in adv.

[scrimski]

Mainly for stabilizing footage or attaching matte layers.

you could try the voodoo tracker

Could I ask where you guys/gals have used the tracking functions within AFX for projects?Rarely, and only limited to 2D tracks. For instance, a tripod shot. Or a sky replacement.

Thanks a lot everyone,



scrimsk thanks for the link



I've not been using AFX that long, so needed reassuring.

Cheers ;-)

I use tracking in After Effects for tons and tons of things, including:

-tracking in still patches to cover things I want to remove from footage
-stabilizing
-tracking in CG things, be it something sitting on a table or an entire matte painting background
-tracking matte layers, both regular 2D and along with scale & rotation, to make rotoing easier and faster
-stabilizing and retracking is neccessary for any splitscreening fx
-corner pinning in screen replacements, billboards, signage, or anything flat
-in the past 6 months or so I've been using tracking to apply to individual mask points

literally, almost every single visual effects shot I've ever done has had something in it tracked for some reason or another.

I made a few video tutorials for friends at SimplyCG.
Maybe some of them will help demonstrate how I use tracking daily.
