great toturial, extra question, i have extra green keys of extra persons without the camera movement, how do i put those persons in place so perspective keeps right, because ive placed them in the scene, fixed position and scale, and it doesnt match with my charachters
If you have shot the extra persons from incorrect perspective, it cannot be fixed easily. All persons should have been shot in position where they are in final part of the frame for the final footage. For example, if somebody is going to be on the left side of the screen, he or she must be shot against green screen so that he or she is on the left side of the screen in the green screen footage. And yes, it sucks if you only find this out later. In theory you could create a 3D model of the person, project the textures from the original green screen camera direction and then move the person around the virtual scene to get another camera angle but that requires full 3D model of said person to be successful. And even then you may have to manually paint the part of the texture that was not visible from the original footage but is now visible in the new position within the camera view. (For example, imagine somebody having a tattoo on their right shoulder. If they were facing camera on left side of the original footage, the tattoo is not visible to the camera. However, if you later decide they "should have been" on the other side of the frame, the tattoo should now be visible. And as a result, you would now have to paint the tattoo to the part that wasn't visible in the original footage. It's possible but very time consuming.)
The same as the response in the other video: "the complete workflow is explained in one of the previous videos, how to link the plane to the camera, how to scale it in order to keep the proportions of the scene and so on. We didn't repeated here to don't repeat the same things in each video"
Having plane origin at camera and using scale to adjust the depth in 3D world was a clever trick that I'll definitely use in the future!
Thank you😀
can you provide green screen footage to practices?

Hi, curious why you didn't use the constraint function to tie the plane to the camera? Thanks
