Boujou and Cinema 4d video tutorials?

Does anyone have any video tutorials using both of these programs integrated, from basics to advanced maybe? Anything on youtube with sound?

The reading tutorials are not going to cut it, not the best way I learn.

Thanks!

View the trailer to the feature film I directed here.

Hey Raptor.

Hey Raptor.

Hey Raptor, thanks for asking. Well yes. I am trying to track my footage in Boujou and create a mesh, to bring that into Cinema 4D and start animating my model on top of that mesh.


I really don't know the workflow at all, I just overheard someone this is how you do it if you want to model something in cinema 4d and have it track to your footage. My footage is somewhat shakey with a person moving in the foreground, but I created a polymask and got a good track. Also there are a few points that show up where i dont want to track, like the sky, i just deleted those thats correct right?

I am using the wizard in Boujou 4
I know how to get up to the scene geometry part, don't know why or what this is for.

Dont know if I should create which or all or some of the following.
origin
x axis
y axis
z axis
xy plane
yz plane
zx plane
line paralel to x axis
line paralel to y axis
line paralel to z axis
line paralel to xy plane
line paralel to yz plane
line paralel to zx plane
known length
planar constraint

Then I adjust the camera solve to the new planar contraints, is that what I want to do?

Then it asks to export the camera to c4d as I chose, and I do it.

But don't I want to create a mesh inside boujou first? Do I want a mesh and none of the scene geometrys?

That is for project 1, being able to animate onto a shot scene.

My project 2 that I wish to do is, replace a sky in 3d space.
So I key out the sky in my compositing program.
Bring that image sequence into boujou.
Load the mask of my sky or create a fresh poly mask in boujou.
Track the sky.
Camera solve, erasing any points that may appear out of the sky.
Dont use any scene geometrys.
Export camera data to c4d.
Load camera in c4d.
Load footage with alpha sky.
Create a sky in c4d and put it in the background.

Any ideas? I have never done any of this, I am attempting to teach myself at the moment. Thanks.
 
I wouldn't worry about creating objects in boujou. I'd leave the modelling to C4D.
------------------------------
For the first scene:
Boujou:

I take it you want to create and animate an object added to a scene that has a person moving in it.
You'll need to remove the tracking from the person. To do that, in boujou...

* Click the 'Import Sequence' button to open the scene.

* Click the 'Add Poly Masks' button and draw a polygon around the person.
Srub the slider and adjust the whole mask or just the points of it to track around the person.
Anything inside of the mask will not be tracked.
Just as a note, you can also r-click on the mask and select 'Invert Mask'. That would omit
everything except the person, if you wanted to track that, which you dont.

* Click 'Track Features'.
* Click 'Camera Solve'.
* Click 'Export Camera'.
Choose an export type of 'Cinema4D(*.c4d).
C4D:

I made a couple boujou-to-C4D getting started vids. You can watch them here...
(click each of the 3 boujou-C4D files, and then the big blue down arrow to download.)

You'll probably want a mesh of the ground to use it as a shadow catcher. To create one you can
download my plugin from here. It creates a polygon whose points are at the same coordinates of
the tacking nulls. Then you can draw your mesh from that.
(See post #14. The source code for the plugin is available in the COFFEE section at C4Dcafe as well)

The sky replacement.

If there are moving objects in your scene you'll need to draw a polygon mask around the moving objects so as not to track them. Othwise I'd also track the rest of the scene as well. That gives more depth information for the camera and helps in placing the sky material later on.

You dont need to have it chroma keyed for that part, only in the final composite. So in C4D you open the tracking data, put the scene in a background object for reference.

Then add a plane with a sky material loaded in the luminance channel.
Position it. Dont worry about compositing it yet. Instead, when your ready to render, hide the background and just render off the sky.

So, now you have an animated sky, and the scene.
You can then use another NLE like AE or Sony Vegas to composite the two.

If you have to do it all in C4D, then you'll need a greyscale mask of the sky cutout from your original chroma key. Then place the original video into a Foreground object with the mask apllied to the alpha channel of the material. With the sky plane in place, render that off. You wont need a background object for that.

solving a multiple camera solve from boujou to cinema

solving a multiple camera solve from boujou to cinema

Hey Gord, I was reading one of your posts on C4d and boujou collaboration.
I have a long video clip. In boujou i have about 5 camera solves on one clip. so it's alll just one solid move. bu when i export the cameras to C4D they all open in the scene in diferent locations. they don't sync up as one solid move.
can you help me solve this problem.

Thankyou,
Christian H:cry:
