Cautions for Shooting Video Snapshots
You can add to an album only the video snapshots with the same

duration (approx. 2 sec., 4 sec., or 8 sec. each).
Note that if you do any of the following while shooting video snapshots, a

new album will be created for subsequent video snapshots.
• Changing the [Movie rec. size].
• Changing the [Sound rec.] setting from [Auto]/[Manual] to [Disable]
or from [Disable] to [Auto]/[Manual].
• Updating the firmware.
The shooting duration of a video snapshot is only approximate.

Depending on the frame rate, the shooting duration displayed during
