clip   =

Source clip(s). At least one is required. Up to four clips are accepted.

Each clip defines a color plane in the output, as defined by the planes and source_planes arguments.

If the clip count is less than the given planes defined, then the last available clip is used as a source for all later planes.

string  planes = ""

The target plane order (e.g. "YVU", "YYY", "RGB"); missing target planes will be undefined in the target.

string  source_planes = "YUVA" or "RGBA"

The source plane order, defaulting to "YUVA" or "RGBA" depending on the video format.

Source clips can even be mixed from greyscale, YUV, YUVA or planar RGB(A) — the only rule being that the relevant source plane character should match with the clip format, respectively.

string  pixel_type =

Set color format of the returned clip. Supports all AVS+ color formats.

clip  sample_clip =

If supplied, output pixel_type will match that of sample_clip.
