Claim:
A moving image editing device which edits and saves a plurality of moving image data as material data, comprising: a processing device; and a memory device connected to the processing device, the memory device storing a program that, when executed by the processing device, causes the processing device to execute, at least in part, a method comprising the steps of: acquiring a material format, which is a moving image format of at least part of the material data; determining whether or not the acquired material format matches a save format, which is a moving image format to be saved; converting the material data into the save format; joining the converted material data, the converted material data being save data, summing up a playback time of not-yet converted material data; comparing the summed up playback time of the not-yet converted material data with a sum of a playback time of the converted material data and a total playback time of the save data; correcting, when the sum of the playback time of the converted material data and the total playback time of the save data is longer by a predetermined time than the summed up playback time of the not-yet converted material data, the sum of the playback time of the converted material data and the total playback time of the save data such that a difference between the sum of the playback time of the converted material data and the total playback time of the save data and the summed up playback time of the converted material data is less than the predetermined time; and setting a remaining portion corresponding to a subtraction of the corrected playback time from an end portion of the playback time of the converted material data, as a portion to be joined.
