I was thinking on getting a motion traker called Icarus. If anyone have used that program and is willing to help me, that would be great.
i just want to know if this would work with a keyed image. in CompositeLab.

I have worked with Icarus some time ago. But I don't understand your question. You have to have some footage. Load this Clip in Icarus and Track the Camera movement. Export the Tracking-data and after that import it in your favourit 3D Application. Add your 3D Object to the scene. At this point you have multiple way to get everything together. One way would be to Render everything in your 3D App. The other way would be to Render your object with an Alpha Channel in an Image-stream. (Make sure you take an Image Format that supports Alpha Channel, like TIFF) The Image Stream can be Imported in CompositeLab and VisionLab of cause. The you can do all other steps to acomplish your scene.

I hope this helps you a bit.

Ok, so I have a question about Icarus. I know it tacks motion in 3d space, whereas the motion tracking application within After Effects does not (It seems to only be able to do motion tracking in 2d space, unless i'm missing something). So, with that in mind, is there some way for me to use icarus to tack something in 3d space, and then import the data into After Effects? What is the best way for me to do 3d motion tracking without a 3d modeling program?

Hi Squid,

You are completly right. AE Tracks only 2D and Icarus 3D. There is an export Format for the Icarus Tracking Data for AE. But Icarus won't be updated anymore. So it could be that it won't work with newer AE Versions. You can buy the software called PFTrack or PFhoe this based on the Icarus Engine and looks very powerfull.

What I don't understand is: Why would you track something in Icarus in 3D and be not willing do use a 3D Object (what you only can build in a 3D Packet) to composite into the Footage?!

I would say use Syntheyes. It's the cheepest motion tracker I've ever seen and it does an amazing job. It's the tracker they used on Transformers, Pirates of the Carribean and other big movies. Not only that, but it exports to almost every 3d app out there as well as AE and they are updating the program all the time.

On the contrary, the cheapest out there is Pixel Farm's PFHoe. It is extremely straight forward, simple (some might say too simple) and works on pretty much any footage. I've used it extensively for our upcoming Stargate fanfilm. For $99, its one of those software tools every serious (but not rich) film maker should have.
