Specifying Crop Points
You can specify that the loaded video or audio clip is to be
cropped before it is transcoded. To do this you must include a
playback
key-value pair in the map. For
example:
{ ... "playback":{ "in":1.5, "out":5.6 } }
The value of the playback
key must be a map
containing the following key-value pairs:
in
-
The point at which the transcoded, published clip is to start, measured from the start in seconds.
out
-
The point at which the transcoded, published clip is to end, measured from the start in seconds.
