Cautions for Shooting Video Snapshots
You can add to an album only 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] (p.193).
• Changing the [Sound rec.] setting from [Auto/Manual] to [Disable] or
from [Disable] to [Auto/Manual] (p.210).
• Updating the firmware.
You cannot take still photos while shooting a video snapshot.
The shooting duration of a video snapshot is only approximate.
Depending on the frame rate, the shooting duration displayed during
playback may not be exact.
