Abstract

La présente invention concerne un procédé destiné au traitement d'une interface utilisateur d'édition vidéo exécutée sur un dispositif mobile à écran tactile. Selon la présente invention, une trame est acquise à chaque intervalle d'acquisition de trame prédéfini à partir de certaines sections d'une vidéo choisie par un utilisateur et est ensuite affichée dans une première région d'interface utilisateur. Ensuite, lorsque l'utilisateur fait glisser deux trames quelconques parmi un certain nombre de trames affichées sur une seconde région d'interface utilisateur sur l'autre côté d'un écran, un clip vidéo qui correspond à une section entre les deux trames choisies est généré et est ensuite inséré à une position sur une ligne de temps correspondant au point auquel le glissement s'est terminé. Par ailleurs, lorsque l'utilisateur touche simultanément deux points sur la première interface utilisateur et fait ensuite glisser ces deux points de contact de sorte à les rapprocher ou à les éloigner l'un de l'autre, l'intervalle d'acquisition de trame est réinitialisé dynamiquement, une trame est à nouveau acquise à partir de la vidéo, et les traitements susmentionnés sont alors répétés.
