a switching step of reselecting the selection region from among the plurality of regions to switch the selection region after the selection step is executed; a recording step of recording each of a pre-switching video which is a video of the selection region before the switching step and a post-switching video which is a video of the selection region after the switching step; a display step of displaying the post-switching video after the pre-switching video is displayed and displaying an insertion video in a period between a display period of the pre-switching video and a display period of the post-switching video; and an adjustment step of adjusting, during a display period of the insertion video, at least one of an exposure amount of the selection region after the switching step, white balance of the post-switching video, or focus of the imaging lens after the switching step. ### Claim 2 (depends on 1) The video creation method according to claim 1, wherein the insertion video

on 1) The video creation method according to claim 1, wherein, in the recording step, the pre-switching video and the post-switching video are combined to create a motion picture file. ### Claim 4 (depends on 3) The video creation method according to claim 3, wherein, in the recording step, the insertion video is excluded from a recording target. ### Claim 5 (depends on 1) The video creation method according to claim 1, wherein the exposure amount is adjusted by adjusting a stop amount for an incidence ray on the imaging lens, and in a case in which the stop amount or the focus is adjusted in the adjustment step, a length of the display period of the insertion video is changed in accordance with a required time for adjusting the stop amount or the focus in the adjustment step. ### Claim 6 (depends on 5) The video creation method according to claim 5, wherein, in a case in which the required time is equal to or longer than a predetermined time, in the display step, the insertion video including information relating to the required time is displayed. ### Claim 7 (depends on 1) The video creation method according to claim 1, wherein the exposure amount is adjusted by adjusting a stop amount for an incidence ray on the imaging lens, and in a case in which the stop amount or the focus is adjusted in the adjustment step, in the display period of the insertion video, an adjustment speed of the stop amount or the focus is faster than in a period other than the display period of the insertion video. ### Claim 8 (depends on 1) The video creation method according to claim 1, wherein a mode for adjusting the focus is selected from among a manual focus mode in which the focus is manually adjusted based on an operation of a user and an autofocus mode in which the focus is automatically adjusted, and in a case in which the manual focus mode is selected, in the adjustment step during the display period of the insertion video, the focus is automatically adjusted.
