Astuce : agrandissement d’une vidéo avec le développement génératif
Modifiez la taille et la forme d’une vidéo avec du contenu généré dans Adobe Photoshop.
Publié le
L'outil Développement génératif de Photoshop permet de convertir des vidéos verticales au format horizontal en quelques clics.
Il suffit de disposer d'un plan filmé sur trépied, sans mouvement sur les bords.
À l'ouverture d'un fichier vidéo, la séquence s'affiche dans le panneau Montage.
Vous pouvez la lire en cliquant sur ce bouton.
Nous allons la convertir au format horizontal en générant du contenu sur les côtés.
Activez l'outil Recadrer.
Avant de cliquer sur Développement génératif, il faut s'assurer que le contenu généré apparaîtra dès le début et se superposera à la séquence originale.
Placez donc la tête de lecture au début de la vidéo et cliquez sur Groupe vidéo 1, sans quoi la génération risque d'être invisible.
Sélectionnez le rapport L/H dans ce menu.
Je choisis 16 : 9.
Développez le recadrage à l'aide des poignées et faites-le glisser pour le positionner.
Cliquez sur Développement génératif, ne saisissez aucun prompt, puis cliquez sur Générer.
Photoshop génère alors trois variantes donnant l'impression qu'il s'agit d'une vidéo horizontale.
Lancez la lecture.
Le résultat est parfaitement réaliste.
À votre tour de convertir l'une de vos vidéos verticales à l'aide du développement génératif dans Photoshop.
Je m'appelle Jesús Ramirez et je vous remercie pour votre attention.
