Canon EOS 60D Instruction Manual page 175

AE lock and exposure compensation cannot be set.
Changing the shutter speed or aperture during movie shooting is not
recommended since it will record the changes in the exposure.
If you use a lens whose maximum aperture changes while you zoom,
you should not zoom while shooting a movie. Zooming while shooting a
movie may record changes in the exposure.
If you shoot a movie under fluorescent lighting, the movie image might
flicker.
With Auto ISO, the standard movie exposure will usually be obtained
even if the light level changes.
When shooting a movie of a moving subject, a shutter speed of 1/30 sec.
to 1/125 sec. is recommended. The faster the shutter speed, the less
smooth the subject's movement will look.
If you playback with "Shooting information display" (p.192) a movie shot
with autoexposure, the shutter speed and aperture will not be displayed.
The image information (Exif) will record the settings used at the start of
the movie shooting.
Set the ISO speed.
