Read up on pre-composing, masking and rotoscoping to integrate your overlays into the scene.
I read about those things, but i don't get how it will help me ?
But who can i put the circle really on the soccer ground ?
see here about 3D Camera tracker. once you track the scene, you can place elements in perspective to the scene.
Today i tried a lot and by using pre composition i manage to do some good stuff, thanks you.
To put the circle like this RB Leipzig’s Secrets Unveiled - The Recipe for Success - YouTube i mean the guy in front of the circle, the only way is to use rotoscoping ? It seems very very long, but maybe i'm not used to it.
this looks to me like one a compositing that does it LIVE - a VIZ type of setup that can create this type of things live. quite popular for enhancing sporting events it has the perspective information of the camera and can perform tracking, keying and placing graphics LIVE. amazing right?
trying to recreate this in post is much harder. 3D Camera tracking won't work with this footage because there isn't enough perspective information. you can 2d track it. as for rotoscoping, my you can use keying to key out the green instead of roto.
here's an example of a setup:
you track the shot using the motion tracker, apply it to a null. create your shape and parent it to the null, add the set matte effect for it and use the video footage with keylight applied as your input+effect layer.
here's the project folder:
this should get you started.
Yeah pretty amazing, i would love to use the same thing !
In effect i try many times and the camera tracking doesn't work.
I didn't understand everything at the moment but thank you very much, this help me so much;
