Tracking Shift from Boujou using in Combustion

[SnapiTT]

Well hello,

sorry for my english. I’ve got the following problem :
I’ve to compose a miniatur tent into a real scene which is around one meter high and in the final scene it must be seen as a 15 meters high..
the scene takes place in a cinema short film of Daniel schreiber “the kabinett”.

my problem isn’t the keying or the compositing, I’ve got big problems on tracking this in Combustion. the material is 16mm filmed and scanned on 1080 24p HD which meands its really “grainy”. So I’ve been trying create nice tracking points in boujou and export them into combustion. is there any possibilty to render the tracking crosses into the sequence to give the combustion tracker simple points to track ?? or can how can I use the shift of the boujou camera for my tent-layer in combustion ?

Why do you want to render tracking crosses? If you can get boujou to track your scene you’re almost done. Bojou can export the 3D track as a combustion scene (*.cws). You’ll get all the tracking data in combustion’s camera.

She would not be better you to render the personage already with “camera” of the Boujou?

Are you not able to see the Boujou tracks in combustion? If this is what your asking, here are the settings for export in Boujou.

Start index: 0
Null Size: 1
Scene scale: 100

Also, make sure the box is NOT checked that says “use default for index null size.”

sorry if i misunderstood your problem:

i don´t quite get why you are tracking a scene which only needs 2d tracking in a package like boujou?

if you have 16mm or an hd equivalent it should track fine in c* even with the heavy grain in it. if not use a degrain-op while tracking and remove it later. you just need to track the 2d position with a 2 point tracker (position, scale, rotation).

if you are talking about a 3d object you want to insert it would make sense to track it in boujou.

hope i got you right.

cheers

Okay thx it seems like boujou is the wrong software for this problem.
I will try again in C*
