Apparatus, method, and medium storing a program, that reduce playback time differences when joining moving images of different formats

摘要

Moving image editing device, method, and storage medium storing a program provide a smart rendering scheme to minimize the variation of playback time, even when editing moving image data that does not match the save format. The format of the moving image data is compared with the save format. The moving image data is converted into the save format. The moving image data is sequentially joined and saved. A portion or the entirety of the moving image data itself is output if the format of the moving image data matches the save format, or the data encoded into the save format after decoding a portion or the entirety of the moving image data is output if the format of the moving image data does not match the save format. The device repeats sequential joining so that the difference in the playback time with the moving image data is minimized.

主权项

1. A moving image editing device that sequentially joins a plurality of material moving image data to thereby generate a single joined moving image data, the moving image editing device comprising:
a processing device; and a memory device connected to the processing device, the memory device storing a program executable by the processing device, the program comprising: conversion instructions configured to convert one of a plurality of material moving image data with respect to format; setting instructions configured to set a portion to be joined among the converted material moving image data; and first adding instructions configured to obtain a first sum of a playback time of the not-yet converted material moving image data and a total playback time of a joined material moving image data; second adding instructions configured to obtain a second sum of a playback time of the converted material moving image data and a total playback time of the joined moving image data; determination instructions configured to determine whether or not a difference between the first sum and the second sum is less than a predetermined value; and joining instructions configured to join the converted material moving image data to the joined moving image data, wherein the joining instructions are configured to: join the converted material moving image data to the joined moving image data when the difference between the first sum and the second sum is less than the predetermined value, and join the set portion of the converted material moving image data to the joined moving image data when the difference between the first sum and the second sum is not less than the predetermined value, and wherein the setting instructions are configured to set the portion to be joined so that a difference between the first sum and a third sum of a playback time of the portion of the converted material moving image data and a playback time of the joined moving image data is less than a predetermined value.
