Recording and Playing Back Movies
B Maximum Movie Length
Individual movie files cannot exceed 4 GB in size or 29 minutes in length, even when
there is sufficient free space on the memory card for longer recording.
• The maximum movie length for a single movie is displayed on the shooting screen.
• Recording may end before either limit is reached if camera temperature becomes
elevated.
• The actual movie length may vary depending on the movie content, subject
movement, or type of memory card.
B Notes About Saving Images and Recording Movies
The indicator showing the number of exposures remaining or the indicator showing
the maximum movie length flashes while images are being saved or while a movie is
being recorded. Do not open the battery-chamber/memory card slot cover or
remove the battery or memory card while an indicator is flashing. Doing this could
result in loss of data, or in damage to the camera or the memory card.
B Notes About Movie Recording
• Memory cards with an SD Speed Class rating of 6 or faster are recommended when
recording movies (A25). Movie recording may stop unexpectedly when a
memory card with a lower Speed Class rating is used.
•
The sounds of zoom control operation, zoom, autofocus lens drive movement, vibration
reduction, and aperture operation when brightness changes may be recorded.
• The following phenomena may be seen in the monitor while recording movies.
These phenomena are saved in the recorded movies.
- Banding may occur in images under fluorescent, mercury-vapor, or sodium-vapor
lighting.
- Subjects that move quickly from one side of the frame to the other, such as a
moving train or car, may appear skewed.
- The entire movie image may be skewed when the camera is panned.
- Lighting or other bright areas may leave residual images when the camera is
moved.
• Depending on the distance to the subject or the amount of zoom applied, subjects
with repeating patterns (fabrics, lattice windows, etc.) may have colored stripes
(interference patterns, moire, etc.) in them during movie recording and playback.
This occurs when the pattern in the subject and the layout of the image sensor
interfere with each other; it is not a malfunction.
