Title
(EN) AUTOMATIC CAMERA ANGLE SWITCHING TO CREATE COMBINED AUDIOVISUAL FILE
(FR) COMMUTATION AUTOMATIQUE D'ANGLE DE CAMÉRA POUR CRÉER UN FICHIER AUDIOVISUEL COMBINÉ
Abstract
(EN)
A system and method are provided for automatically concatenating two or more audiovisual clips containing video input from multiple cameras, and producing a combined audiovisual file containing video that switches between the two video inputs. In some examples, two video inputs and an audio input are recorded synchronously and are synchronized. The audio input can be sampled to locate low-noise audio events. The audiovisual file contains video that switches between two or more camera angles at the low-noise audio events. In one aspect, pauses are automatically removed from the audiovisual files. In another aspect, the system detects switch-initiating events, and switches between camera angles in response to detecting a switch-initiating event.
(FR)
L'invention concerne un système et un procédé qui sont prévus pour concaténer automatiquement au moins deux séquences audiovisuelles contenant une entrée vidéo provenant de multiples caméras, et produire un fichier audiovisuel combiné contenant une vidéo qui commute entre les deux entrées vidéo. Dans certains exemples, deux entrées vidéo et une entrée audio sont enregistrées de manière synchrone et sont synchronisées. L'entrée audio peut être échantillonnée afin de localiser des événements audio à faible bruit. Le fichier audiovisuel contient une vidéo qui commute entre au moins deux angles de caméra au niveau des événements audio à faible bruit. Selon un aspect, des pauses sont automatiquement supprimées des fichiers audiovisuels. Selon un autre aspect, le système détecte des événements de déclenchement de commutation, et commute entre des angles de caméra en réponse à la détection d'un événement de déclenchement de commutation.
