If it exists, the playlist is updated so as to insert a blank scene of a length immediately before these skewers (S22). At this time, if there is an existing blank scene power s , the playlist is updated so that the length of the blank scene is increased by L.
  • step S13 If it is determined in step S13 that this scene editing is neither the introduction of a new scene nor the expansion of an existing scene, it is checked whether or not the existing scene is deleted or reduced (S23). If neither is found, this process ends. If any, it is checked whether there is a skewer after the interrupt point of the specified track (S24). If not, the process ends. If so, it is checked whether there is already a blank scene immediately before the relevant skewer of the track to be deleted or reduced (S25). If not, the process proceeds to the subsequent step S27, and if so, the playlist is updated so that the length of the blank scene is extended by the scene shortening length (S26), and this process ends.
  • the scene shortening length is the length of a blank scene when a scene is deleted. After that, the playlist is updated so that a blank scene of the length of the reduced scene length is inserted immediately before the skewer (S27).
  • the blank count process is started each time the scene is edited, and counts the current number of blank scenes in each track and reflects the count on the blank scene count display in the root window.

  • S42 it is checked whether or not this scene is a blank scene (S42). If it is not a blank scene, the process proceeds to step S45 described below. If it is a blank scene, highlighting such as blinking of the scene is performed on the time line display of the root window (S43). At the same time, the corresponding video data is read from the disk and displayed on the monitor.

If there is an instruction, check whether the next scene data s exists in this track (S45), and if there is, return to step S42 to search for a subsequent blank scene in the same track as above. I do. When there is no more scene data in the same track, it is checked whether the next track exists (S46). If it exists, the track number n is incremented (S47), and the process returns to step S41 to repeat the above-described procedure for a new track, and terminates this processing if it does not exist.
  • the skewered scenes are integrated into time. While moving in the axial direction, the blank period without any substantive data is inserted in the blank period in any of the resulting tracks, but instead of the blank line, the blank line immediately before the blank period is used. A margin after the scene or a margin before the immediately following scene may be inserted.
  • the start position and end position of each cut scene are determined by the playlist, but as can be seen from the record in Fig. 7, before and after the cut scene, another continuous scene
  • the scene is latent. This area is called the margin. According to this method, generation of a blank scene itself can be prevented.
  • the user can determine in advance which part of the scene to insert, or inquire of the user at the time of the insertion.
  • the present invention can be used for manufacturing and using a non-linear video editing system.
  • Advantageous Effects of Invention According to the present invention, it is possible to guarantee the prevention of occurrence of a shift for a video scene and an audio scene which should not be shifted from each other, and has an effect of preventing an erroneous operation by a user.

Abstract

Plusieurs plans (scènes a-d) sont affichés séquentiellement dans le temps en parallèle sur un écran externe d'un système de montage vidéo non linéaire pour chaque piste. L'utilisateur colle un plan visuel et un plan sonore pour lesquels la mise en correspondance du bloc image doit être assurée sur plusieurs pistes (V, A1, A2) au moyen d'une 'broche'. La broche empêche tout déplacement entre le plan visuel et le plan sonore, lesquels ne doivent pas être déplacés l'un par rapport à l'autre. Lorsqu'une intervention de l'utilisateur provoque un déplacement temporaire entre les plans collés d'une piste, un moyen de commande déplace les plans collés ensemble dans la direction de l'axe temporel et insère un plan vide ne contenant aucune donnée d'entité dans un intervalle vide d'une piste arbitraire produite par le déplacement. Le nombre des plans vides de chaque piste est compté chaque fois qu'un montage est exécuté et il est affiché sur un écran. Le plan vide peut être recherché.
