rate displayed in the monitor during shooting and playback. At frame
sizes/rates of 3840 × 2160; 60p and 3840 × 2160; 50p, the frame rate of
footage output via HDMI will differ from the selected value.

6 If the memory card has a capacity of over 32 GB, recording for each
movie will continue up to the maximum movie length. Movies
recorded to cards with capacities of 32 GB or less reach their
maximum length when 4 GB of footage is recorded, and this is
reflected in the value for time remaining shown in the monitor.

(L-people)], [Wide-area AF (L-animals)], [Auto-area AF (people)], or
[Auto-area AF (animals)] for AF-area mode does not enable face/eye-
detection or animal-detection AF.
9 Movie quality fixed at [High quality].
10 If the memory card has a capacity of over 32 GB, recording for each
movie will continue up to the maximum movie length. If the card's

of these files will be a maximum of 4 GB in size. The number of files
and the length of each file vary with the options selected for [Frame
size/frame rate] and [Movie quality].
