View Full Version : Match Moving - Best Method
Can anyone suggest or tell me of the best way of 'match moving' footage in order to composite 3D elements into it.
for instance if I want to change the look of a building etc.
Is it best to just bring the footage into cinema as a background material or something?

Here is a link that might help you.
It's a free match moving program (at least for non-commercial use). Check it out:

Thanks for that but I'm a mac user, I'm really looking for a way in which I could do this by hand so to speak, much like rotoscoping instead of using blue screen.

ok... here's a way, but it doesn't really take into account much camera movement, just camera pitch and yaw. put the footage on a background plane. find a point that is visible in each image (close to the centre as possible). and use a spline path tool to manually by hand create a point at each frame on that point. then make the path linear once you've done ( you don't want inbetween points). Next attach a null to that path and target the camera at the null. that should take care of one aspect of the matching.
with regards full camera movement. well for jurassic park the way they did it was to cover the ground with ping-pong balls evenly spaced out, they then modeled the landscape and the camera movement using proprietry software... but you can do something similar yourself if you can find some objects on the ground that you can track, and you know how far apart they were etc you can create virtual counterparts (nulls) and manually move the camera per frame to match these objects up... but this is incredibly intensive. unfortunately c4d has nothing like maya live as far as i'm aware... but mebbe sometime soon someone will write a plugin.
anyhow those are onyl two possible ways of doing this... good luck. you can of course do it in post which would probably be easier (after effects has some good matching tools) although if there's too much camera movement it will give it away completely. but it would be faster. i hope this helps
