Focal plane
Owing to the characteristics of the pickup elements (CMOS image sensors) for reading video signals, subjects
that quickly move across the screen may appear slightly skewed. Since a CMOS sensor typically captures a row
at a time within approximately 1/60th or 1/50th of a second (depending on refresh rate) it may result in a “rolling
shutter” effect, where the image is skewed (tilted to the left or right, depending on the direction of camera or
subject movement).
Flash band
If you film a strobe or quick-flashing light, brightness may differ between the upper and lower halves of the
picture. See the Focal Plane explanation above for clarification of this occurrence.
Flicker
If recording under lighting produced by discharge tubes, such as fluorescent, sodium, or mercury-vapor lamps,
the screen may flicker, colours may vary, or horizontal stripes may appear distorted. In such cases, turn the
anti-flicker setting on. Depending on lighting types, such occurrences may not be improved with the antiflicker
setting. It is recommended to set the shutter speed to 1/100 sec. in the areas of 50 Hz power supply frequency and
to 1/60 in the areas of 60 Hz.
