Levels(clip clip[, float min_in, float max_in, float gamma=1.0, float min_out, float max_out, int planes=[0, 1, 2]])¶
Adjusts brightness, contrast, and gamma.
The range [min_in, max_in] is remapped into [min_out, max_out].
For example, to convert from limited range YUV to full range (8 bit):
clip = std.Levels(clip, min_in=16, max_in=235, min_out=0, max_out=255, planes=0) clip = std.Levels(clip, min_in=16, max_in=240, min_out=0, max_out=255, planes=[1,2])
The default value of max_in and max_out is the format’s minimum and maximum allowed values repsectively. Can be specified for each plane individually.
- Clip to process.
- Controls the degree of non-linearity of the conversion. Values greater than 1.0 brighten the output, while values less than 1.0 darken it.
- Specifies which planes will be processed. Any unprocessed planes will be simply copied.
