Salut à vous, je commence depuis peu sur after effects cs5, et je manque de connaissance . Je vais être rapide et clair: je voudrais faire suivre l'incrustation d'une image ou vidéo sur le mouvement de ma tête masquée d'une seconde peau spéciale chroma key :mrgreen: , et je ne trouve aucune explication assez précise sur le net. Merci d'avance .

    And what exactly would you do with this? Of course you can run around on set with green hood on set al lday, but what is this supposed to do? If you want to replace your head, then this is completely not necessary, anyway. Eitehr way, you need to explain better. Souhnds like you got it in your head to replace your head with a 3D head, which is a completely different thing and has very little or nothing to do with AE.

    Salut à toi. Je veux juste mettre une cagoule verte chroma key, et y faire apparaître des images ou vidéo, pendant que ma tête sera filmée en plan rapprochée avec une caméra fixe. Vu que je parlerai face caméra, j'aurais toujours de petits mouvement de tête, et je veux que les incrustations suivent sur la cagoule.

    As I already said, such stuff tends to require more elaborate tracking or even 3D geometry-based matchmoving. The human eye has a tendency to detect even the slightest issue with faces dur to that "uncanny valley" thing. Just keying it out will very likely not suffice. If at all doable in Ae you would have to include distortion effects like Mesh Warp in your plan to conform whatever texture/ overlay you are going to use to the contours and ideally you would probably use advanced morphing/ warping plug-ins like RE:Flex. As a minor make sure you have some visible contour lines or tracking markers to at least get critical items right, even if it means additional manual masking.
