Canon 814XL-S - Manual (Page 82)

With the filming mode dial set at P.S, you can
fade both picture and sound simultaneously. To
finish a scene with a fade-out:
1. Rotate the fade lever to C while filming.
2. Keep the film drive engaged, and the camera
will automatically shut itself off when the
fade-out has been completed. This auto­
matic stop mechanism is a safety device
that prevents the unintentional filming of
blacked-out frames. (If you do want to black
out a few frames after fade-out, keep the fade
lever at C, take your finger off the shutter
release button, and then press it again.)
Be
sure to hold the fade lever at C until the
film drive automatically comes to a stop.
Otherwise, the shutter blades will re-open and
the fade-out will not be completed.
To begin a scene with a fade-in:
1. Hold the fade lever in the C position for
approximately five seconds while the shutter
blades close.
2. Press the shutter release lever and then
release the fade lever to its 0 position once
you hear the sound of the film transport,
indicating that filming has began.
