Abstract

L'invention concerne un procédé d'application de filtre pour un fichier vidéo. Le procédé consiste à, selon la séquence de trames temporelles, préconfigurer des matériaux vidéo utilisés comme filtres, et selon les différents matériaux vidéo utilisés comme filtres, préconfigurer des matériaux de musique mis en concordance; après la sélection par un utilisateur d'une vidéo à traiter, fusionner les matériaux vidéo utilisés comme filtres et la vidéo à traiter en fonction d'une corrélation temporelle de manière à obtenir une vidéo à images fusionnées; et ensuite, fusionner également les matériaux de musique concordant avec les matériaux vidéo utilisés comme filtres et la vidéo à images fusionnées de façon à obtenir une vidéo de fusion audio-vidéo. On peut ainsi réaliser l'édition automatique d'une vidéo, ce qui permet à l'utilisateur d'économiser beaucoup de temps et d'énergie.
