Basic Operations of Movie Recording and Movie Playback
B Notes About Recorded Movies
• There may be some degradation in image quality when digital zoom is used.
• The sounds of zoom control operation, zoom, autofocus lens drive movement, movie
vibration reduction, and aperture operation when brightness changes may be recorded.
• The following phenomena may be seen on the screen 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, colored stripes
may appear on subjects with repeating patterns (fabrics, lattice windows, etc.) 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.
B Notes About Vibration Reduction During Movie Recording
• When Movie VR (A151) in the movie menu is set to On (hybrid), the angle of view (i.e.,
the area visible in the frame) becomes narrower during movie recording.
• When using a tripod to stabilize the camera during recording, set Movie VR to Off to
prevent potential errors caused by this function.
B Notes About Autofocus for Movie Recording
Autofocus may not perform as expected (A76). Should this occur, focus using manual
focus (A63, 64) or try the following:
1. Set
Autofocus mode in the movie menu to Single AF (default setting) before starting
movie recording.
2. Frame another subject (positioned at the same distance from the camera as the intended
subject) in the center of the frame, press the b (e) button to start recording, and modify
the composition.
