During Movie Shooting, The Exposure Becomes Bright Momentarily; When The Movie Is Played, The Subject Looks Distorted; The Movie Cannot Play - Canon EOS 5D MARK II Instruction Manual

Troubleshooting Guide
During movie shooting, the exposure becomes bright
momentarily.
® Changing the aperture during movie shooting is not recommended
since changes in the exposure, due to the drive of the lens aperture,
will be recorded.
® If you use a lens whose aperture changes while you zoom, you should
not zoom while shooting a movie. Zooming while shooting a movie
may record changes in the exposure.
When the movie is played, the subject looks distorted:
® During movie shooting, if you quickly move the camera left or right
(high-speed panning) or shoot a moving subject, the image might look
distorted.
When I shoot still photos during movie shooting, movie
shooting terminates.
® To shoot still photos during movie shooting, using a CF card
compatible with UDMA transfer rates is recommended.
® Setting a lower image-recording quality for still photos and shooting
fewer continuous still photos can also resolve the problem.
The movie cannot play.
¢_ Movies shot with another EOS camera might not play on this camera.
® Movies edited with a personal computer using the provided software,
etc., cannot be played with the camera.
When the movie is played, camera operation noise canbe heardl
® If you operate the camera's dials or lens during movie shooting, the
operation noise will also be recorded. Using an external microphone
(commercially available) (p. 141 )is recommended.
