Slow or quick motion effects can be obtained by
recording with a system frequency or number of
frames set to a value that is different from the
target frame frequency. On the other hand,
normal speed video can be obtained by recording
with the number of frames set to the same value
as the target frame frequency.
Typical examples of using SR Motion
