Cam match/track animated car to moving backplate

[Morne]

Hi all

Do I need SynthEyes for this and do I need dimensions of the road? I mean if I have moving footage from an unknown source or even a DIY footage source of a road that curves and slopes etc and want to add my animated car onto it, do I need markers or do you get software/plugins that does all this for you?

i used that free one many times. works nicely. icarus i think it is

[Morne]

do you always need dimensions on can the tracking sofware figure things out? I mean if I have a shot of Godzilla running around in town, do I need measurement for building etc? And the car example, do you need dimensions for such things?

[Da_elf]

it autotracked and gave tracking points. if i knew the distance between two points then in max i would make sure it was scaled correctly betwen the two points

[Morne]

Hmmmm yes that makes sense to know the distance betweeb at least two points to get scale. So in my example I caould geuss that width of the road and take it from there.

Thanks for the info Da_elf

I'll probably at some point get Syntheyes. Seems icarus doesn't have any more tech support and can't be getting from any "legal" sources anymore.

Syntheyes is a great program - having measurements is great but most of the time I don't use them - it'd be really useful if you were doing a match move of a locked off set for example but on a road there's no guarantees. As da elf mentioned you can put in rough coordinates for the distance between two points (make an educated guess) and it'll give you a fairly accurate scene scale. Most of the time I fudge these things - I get myself a good flat ground plane for the main surface and try and get flat surfaces for anything else that my 3d will interact with - a car on a road should be very easy to do though.

I do exactly the same. Syntheyes is a v good program and priced well
