Abstract
(EN)
The invention discloses a method and apparatus for generating video files in video conversation. The method includes: one or more videos are displayed at the preset positions on a screen; the screen is captured with preset size and frequency to generate multiple image frames; and the multiple image frames are synthesized with synchronous audio frames to generate a video file. The record problem of a video conversation between two parties or among multiple parties is solved by the invention. Thus a video conversation between two parties or among multiple parties can be recorded on a screen. The video size of each party during recording can be adjusted based on the user requirements for the recording definition, and the screen capture frequency during the process of screen capture can be adjusted based on the user requirements for the image recording quality. Thereby the recording process in video conversation is more reasonably optimized, and the communication and storage resource are more sufficiently used.

La présente invention concerne un procédé et un dispositif pour générer des fichiers vidéo dans une conversation vidéo Le procédé comprend les étapes suivantes : une ou plusieurs vidéos sont affichées à des positions prédéterminées sur un écran ; l'écran est capturé avec une dimension et une fréquence préconfigurées pour générer des trames d'images multiples ; et les trames d'images multiples sont synthétisées avec des trames audio synchrones pour générer un fichier vidéo. Le problème de l'enregistrement d'une conversation vidéo entre deux parties ou entre de multiples parties est résolu grâce à la présente invention. Par conséquent, une conversation vidéo entre deux parties ou entre de multiples parties peut être enregistrée sur un écran. La taille de la vidéo de chaque partie pendant l'enregistrement peut être ajustée sur la base des exigences de l'utilisateur pour la définition d'enregistrement et la fréquence de la capture d'écran pendant le processus de la capture d'écran peut être ajustée sur la base des exigences de l'utilisateur concernant la qualité d'enregistrement de l'image. De ce fait, le processus d'enregistrement dans une conversation vidéo est optimisé de manière plus raisonnable et la communication ainsi que les ressources de stockage sont utilisées de manière plus adéquate.
