Troubleshooting Guide
Camera operation noise can be heard when the movie is
played back.
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) is recommended (p.266).
The movie has still moments.
During autoexposure movie shooting, if there is a drastic change in the
exposure level, the recording will stop momentarily until the brightness
stabilizes. In such cases, shoot in <a> mode (p.237).
No picture on the TV set.
Check that the HDMI cable or stereo AV cable's plug is inserted all the
way in (p.312-315).
Set the [53: Video system] correctly to [NTSC] or [PAL] (depending
on the video system of your TV set).
If [51: Wi-Fi/NFC] is set to [Enable], the camera cannot be connected
to a TV set. Set [Wi-Fi/NFC] to [Disable], then reconnect the camera
to the TV set with the HDMI cable or stereo AV cable.
There are multiple movie files for a single movie shoot.
If the movie file size reaches 4 GB, another movie file will be created
automatically (p.247).
My card reader does not recognize the card.
Depending on the card reader and computer OS used, SDXC cards
may not be correctly recognized. In such a case, connect your camera
to the computer with the interface cable, then transfer the images to
your computer using EOS Utility (EOS software, p.419).
I cannot resize the image. I cannot crop the image.
JPEG c and RAW images cannot be resized or cropped (p.329,
p.331).
