There is provided an information processing apparatus, and a method to improve operability of the information processing apparatus when a user manages still image files in a case where a still image is extracted from a moving image file and stored as a still image file. In information processing apparatus and the method, a moving image file is selected from a plurality of moving image files and is reproduced, and a folder corresponding to the selected moving image file is created. A still image file is generated based on a video frame extracted from the moving image file being reproduced, and the generated still image file is stored into the created folder in association with the folder. When another moving image file is selected, another folder is newly created, and a still image file generated from the other moving image file being reproduced is stored into the other folder.

Information processing apparatus, method for controlling the information processing apparatus, and recording medium

A video recording apparatus is provided that can provide the user with information as to whether or not scheduled image captures will fit into a recording medium or information as to how many retakes are possible. The apparatus obtains, for each scene to be captured, the duration of a cut to be captured from scenario information in which the duration of each of the cuts constituting the scene is specified. The recordable duration is calculated from the remaining capacity of the recording medium in which video data is to be recorded and a recording bit rate of the video data, and the number of image captures that can be taken for the cut to be captured is calculated from the calculated recordable duration and the obtained duration. The calculated recordable duration and the calculated number of image captures that can be taken are displayed on a display unit.

Apparatus and method for video recording

An apparatus comprises a generation unit that newly generates a folder by a predetermined program; an association unit that associates the generated folder by the program other than the predetermined program with the predetermined program; a record unit that records management information, the management information being for identifying whether folders used by the predetermined program have been generated or associated; a selection unit that selects a desired folder from among the folders used by the predetermined program; an identification unit that identifies whether the selected folder has been generated or associated with reference to the information recorded in the memory; and a deletion control unit that performs control of when the selected folder is the generated folder, deleting the selected folder, and when the selected folder is the associated folder, cancelling the association without deleting the selected folder.
