Data rate/recording time@24 fps; Apple ProRes
TM
is a variable bit rate
codec, meaning that the available recording time is subject to the
image content. The number given in the table is the MINIMUM
available recording time. When image content is easily compressed
without loss of image quality, the available recording time may exceed
the number given in the table.
Also note that the available recording time is listed for 24 fps. A lower
sensor frame rate will increase the available recording time, while a
higher sensor frame rate will decrease it.
For a detailed table of available frame rates and possible codec/card
combinations, please refer to the Chapter FPS on page 70.
