Hasta La Motion!

Hey all,

I’m a novice in terms of match moving and just want to ask a couple of questions before I get my hands really dirty.
I want to implement a live scene with an actor into a fully cg scene.
At my disposal I have 3ds Max 9, AE CS4 and Boujou 4.
I am very familiar with Max and AE, but alas not in Boujou yet..

The scene has a guy starting off screen. He then runs across and the camera which follows him for about 100 frames. He then goes out of the screen.
I have run the footage through boujou, both after and before editing out the screen. After camera solving there were almost no trackers left. And not a single one that persisted through the scene.

1.First a real noobie question: Should I edit out the green screen first or after camera solving?

2.I have read something about hand tracking. Would this be a solution for me and how would one go about doing it??

3.In 3ds Max how should I best track the camera motion??

Appreciate all replies and help!
Will provide more info if needed..

Hello all,
I learned that some of you don’t find Cinema 4D inquirers apropriate for this VFX forum, but I guess people here are using it anyway so I really hope that I can get help to finally sorting out this issue. I haven’t had any luck in other forums and it seem that it’s not only me suffering from this.

The problem is that the matchmove doesn’t line up with my footage inside of C4D. I’m learning Boujou 5 and C4D R11 on a Mac btw.

This is what I do:
After that I’m content with my solve and Scene Geometry adjustments in Boujou I export it as a .c4d.
My export/import settings match my footage in terms of fps, fields etc.

Here, in Export camera, I’m not sure what to set "Scale Scene By", for C4D? I’ve done many tests, starting by leaving it to default.

Opening it in C4D, the 3D point cloud is inside the camera (as many others described this problem before).
I’ve tried the recommendation of grouping all the track points, that comes within the camera, into a Null, and placing it outside the Top Null tree. Then I change the new Nulls coordinates to 0. This enhance the situation – now I can view the point cloud through the exported camera – but it doesn’t line up with my matchmoved video I have as reference on a Background object.
And I’m not talking about a little frame slip here!
Not only the scale but the angle is in miss match.

Anyone?

Hey I am trying to export from Boujou and have it set up properly in C4D.

The first problem I am having is that the point cloud does not animate when I bring it in. I know I don’t need the cloud but I know that since it isn’t moving. The camera isn’t as well.

Second. I dont know if my scale is off or something. However I keep messing with it and it changes. But the point cloud is in the far distance compared to where it should be, and when I try and adjust the cameras Zoom nothing happens.

I am using Boujou 5 and Cinema 4d 11.5.

And thank you to all in advance, I really need help as quick as possible.

I was set a challenge today to see if it’s possible to track a piece of footage of a fighter jet and then add in missiles under the wing. So far so simple, but the footage is shot with a long lens with the jet high in the sky doing a simple bank to the left. Nothing passes in the background other than blue sky.
When I track this in Syntheyes using manual placement of trackers (it’s really blurry SD footage) I can get a track that results in a fairly steady motion but not spectacular.
Is this the kind of shot with so little parallax that it won’t track at all or am I missing out a stage?
The issue seems to be that if I solve as a tripod shot I get a crazy high hpix error, or if I solve on automatic the jet stays still and the camera moves and the missile I put in spins in place. Theoretically that last option could work if I could work out the focal length perhaps, but I’m at a loss as to how to work this out. Seems advanced for a novice matchmover.

i get really a hearth attack the next days, because if i export my tracks with the primitive objects, i wont import them in 3dsmax

i can import the max file with the tracking data and camera, of course i can import the tracking object with his tracking information, but the 3ds.file with the primitive object doesnt work! (improper file format)

i export the scene from pftrack as fbx file that works but i have problems with the timing at the background view (img sequenz)

i really need help please
