End recording.
Press the movie-record button again to 
end recording. Recording will end 
automatically when the maximum length 
is reached, or the memory card is full.
Maximum Length
The maximum length for individual movie files is 4 GB (for 
maximum recording times, see page 70); note that depending on 
memory card write speed, shooting may end before this length is 
reached (
Taking Photographs
To take a photograph while recording is in progress, press the 
shutter-release button all the way down. Movie recording will end 
(the footage recorded to that point will be saved) and the camera 
will return to live view. The photograph will be recorded at the 
current image area setting using a crop with an aspect ratio of 
16 : 9. Note that the exposure for photographs can not be 
previewed during movie live view; mode e, f, or g is recommended 
but accurate results can be achieved in mode h by adjusting 
exposure during live view photography (
0 45) and then rotating 
the live view selector to 
1 and checking the image area. Exposure 
compensation for the photograph can be set to values between –5 
and +5 EV, but only values between –3 and +3 can be previewed in 
the monitor (
The Count-Down Display
A count down will be displayed 30 s before movie recording ends 
automatically (
0 51). Depending on shooting conditions, the 
timer may appear immediately when movie recording begins. 
Note that regardless of the amount of recording time available, live 
view will still end automatically when the timer expires. Wait for 
the internal circuits to cool before resuming movie recording.
