Nuke greenscreen 3dtrack

Hi
I got a greenscreen footage with a actor and camera movement..
I tracked the footage with pftrack and brought it ito nuke
Now i am starting with mattepainting and creating an enviroment...
Now for the problem...
Is it better to merge the keyed actor at the end over my 3d enviroment,,what i am doing atm
And the track is stable,,,or is the workflow to put the greenscreened actor on a card?
I tried that,,but then the actor stays not perfectly on the floor and jumping a bit

Hey Zwergnase

how did you check that your camera track is good? Have you tried to put test object (box) in the place near the actor on the floor for example?

Are you using a lens distortion?

you don't need to put your green screen on any cards

cheers
Vlad.

Thx

Thx for reply..
I managed the problem..
The track is stable i am using several testobjects
But instead of using the keyed actor as material on a card..i used a cameraprojection of it with the scene camera on the card..
Now its stable..the actor is in the right place,,and i can use cards in the foreground of the actor...
