Dans Firefly Video, la référence de mouvement consiste à charger une vidéo pour reproduire son mouvement de caméra dans la séquence générée.
Vous pouvez ainsi donner vie à vos idées avec une précision accrue.
Je m'appelle Kelsey Brannan, alias Premiere Gal sur YouTube, et je vais vous montrer comment faire.
Sur la page Générer une vidéo, je fais défiler jusqu'à la section Caméra.
Charger une référence de mouvement
Ensuite, je clique sur Charger une vidéo, Votre appareil pour charger ma référence de mouvement.
J'ai filmé cette vidéo avec mon téléphone en tournant autour de mon chien.
Je veux en effet générer une vidéo où la caméra se déplace autour du sujet, quel qu'il soit.
Firefly extrait uniquement le mouvement de la vidéo, en l'occurrence un travelling circulaire.
Je choisis maintenant un style prédéfini, par exemple, Cinéma, puis je saisis un prompt.
Détailler un prompt
Pour l'enrichir, je clique sur Optimiser le prompt.
Notez qu'on ne peut pas ajouter d'image de référence en plus de la référence de mouvement.
Voilà pourquoi il faut revoir le prompt et inclure un maximum de détails.
Je clique maintenant sur Générer.
Générer et examiner le résultat
Voici le résultat.
Comme le prouve cet exemple, il suffit de filmer le mouvement souhaité pour votre vidéo avec votre smartphone, puis d'utiliser Firefly pour concrétiser votre projet.
J'espère que cette vidéo vous a plu et je vous dis à bientôt.
Bye.
