BlankClip
|

|
|
=========
|
||
|
|
|
||
|
|
.. function:: BlankClip([vnode clip, int width=640, int height=480, int format=vs.RGB24, int length=(10*fpsnum)/fpsden, int fpsnum=24, int fpsden=1, float[] color=<black>, bint keep=0, bint varsize=0, bint varformat=0])
|
||
|
|
:module: std
|
||
|
|
|
||
|
|
Generates a new empty clip. This can be useful to have when editing video or
|
||
|
|
for testing. The default is a 640x480 RGB24 24fps 10 second long black clip.
|
||
|
|
Instead of specifying every property individually, BlankClip can also copy
|
||
|
|
the properties from *clip*. If both an argument such as *width*, and *clip*
|
||
|
|
are set, then *width* will take precedence.
|
||
|
|
|
||
|
|
If *keep* is set, a reference to the same frame is returned on every request.
|
||
|
|
Otherwise a new frame is generated every time. There should usually be no
|
||
|
|
reason to change this setting.
|
||
|
|
|
||
|
|
If *varsize* is set, a clip with variable size will be returned. The frames
|
||
|
|
themselves will still have the size given by the width and height arguments.
|
||
|
|
|
||
|
|
If *varformat* is set, a clip with variable format will be returned.
|
||
|
|
The frames themselves will have the format given by the format argument.
|
||
|
|
|
||
|
|
It is never an error to use BlankClip.
