How do you input camera back values if your using stock and have no idea what the footage was shot on? Is this a big thing if you cant input anything?

Thanks people!

It's Boujou, and it doesn't matter!:^) I JUST tracked two very impossible shots not knowing a thang about the scene. It tracked like magic. I had to repo some of the objects in my 3d scene, but it didn't effect the final render. Use the Bijou wizard utility. I'm going to even start using it for my Flame sessions as it leaves flame's tracker in the dirt.

Usually if you don't know the proper film back settings you can leave it blank and boujou will try to calculate it based on the image size.

After it's done tracking, you should place some simple geometry in your 3D scene and then render it out, excluding the background. Take your renders into Shake or Combustion or whatever you use, and then layer them overtop of the original plate. If everything lines up the same as it does in your 3D viewport, you should be good to go.

Just out of curiousity, what is the resolution of your footage?

Thanks for the replies guys, I might give the wizard function and see how that works. Im currently trying to track some stock footage which contains a camera (in a plane) flying above some farmers fields. Its PAL res. and isnt overly lossless quality. My solve seems to make my 3d objects slightly slide when I run them together. Have a feeling its due to the lack of points for boujou to track.

Thanks again!

actualy, you would not need more than 6 to 10 "good" trackers to be able to get a solution...

me personaly, i think those wizard driven trackers are pants... manual control is fundamental to get good feature tracking (and thus a good camera calibration)...

having said that, scrap boujou and go for Syntheyes... you won't regret it ;)

If you're using boujou3, you can tell it the size of the features to track, or which colour channel to track, and a few more options under the "advanced" settings once you click on "track features".

Don't forget you can add gold tracks, locators, and target tracks to improve your solution. I've had to work with some pretty crazy shots for a few movies, and those features are really handy to learn and use.

Wish I knew that when I started out... First shot I tracked was the rooftop scene for Dawn of the Dead. I couldn't get it to work because I didn't know Boujou well enough. Hand tracked the entire thing :(. Don't do that, hehe

when i say manual control i am refering to manualy placing tracks and choosing features... not manualy tracking... heh

and ralphy, cool, it must have been a realy nice track job cus i didnt notice... u have any link to your works mate? =)

Thanks Maddog =D ... It took a while to do, and it wasn't perfect, but the comp artist was able to smooth out the rest of the track in 2D land. I love compositors :)

I'm working on a website for my stuff right now, but I don't have anything online at the moment. Soon though! =)

boujou is.... a compositing/camera matching program? or is it a full 3d studio?

is the camera matching better than that in 3dsmax? max requires 6 points as well. The forbidden fruit was an Apple. Steve Jobs wants your souls.

Boujou is a camera tracker.

It's light years ahead of Max's one.

Thanks again guys, its weird. In Boujou my solve looks perfect, Ive dropped in some test geometry and it tracks seemlessly but when I run the script in max my geometry still seems to slide. Any one have any ideas why this might be?

I've only ever used Boujou with Maya, but I assume the workflow is about the same...

When you open up your exported scene into max, you're probably presented with a camera and a bunch of boujou locators. Scrub through your timeline and see if those locators stick to the footage. If they do, just make sure your Max geometry is snapped to a solid locator, and it should stick.

You just have to always be sure that you put your 3D geo where Boujou WANTS you to put it. If it has 10 locators on a tabletop, and you put your teapot nowhere near those locators, it's gonna slide.

Guys, just quickly. How do you guys set your footage within max? On a plane locked to the camera or in the viewport via the enviroment slot?

Thanks again!
