An apparatus for processing video data comprising:
- a play back unit configured to play back an original video file including original video data from a recording medium;
- an instructing unit configured to instruct an image effect process on the original video file recorded on the recording medium;
- an effect process unit configured to add an image effect of the image effect process to a designated period of the original video data played back from the recording medium and to generate effect video data of the designated period different from the original video data in accordance with an instruction of the image effect process from said instructing unit, the effect process unit adding the image effect of a type selected from a plurality of types of image effects;
- a recording unit configured to record an effect video file including the effect video data generated by said effect process unit on the recording medium where the original video file is recorded;
- and
- a play list processing unit configured to generate a play list file to control a playback sequence of the original video file and the effect video file recorded on the recording medium so that the original video file and the effect video file are subsequently played back,
- wherein the play list file includes effect type information indicating the type of the image effect of the effect video data recorded on the recording medium,
- wherein the play list file includes a first video track which includes first content information designating the original video file recorded on the recording medium and first reference information indicating play back time of the original video file, and the play list file further includes an effect video track which includes second content information designating the effect video file recorded on the recording medium and second reference information indicating play back time of the effect video file,
- wherein said recording unit further records the play list file generated by said play list processing unit on the recording medium where the original video file and the effect video file are recorded, and
- wherein said play back unit plays back a remaining period of the original video data other than the designated period of the original video data and the effect video data to which the image effect of the type indicated by the effect type information included in the play list file reproduced from the recording medium is added subsequently from the recording medium in accordance with the play list file reproduced from the recording medium.
