| This feature is specific to AviSynthPlus. It is not supported in other AviSynth versions. |
Contents[hide] |
These conversion filters are to allow filters that use 16-bit video in a pseudo-8-bit colorspace to interact with AviSyth+ high bit depth formats. They are intended to serve as a stopgap until more plugins appear supporting true high bit depth.
Notes
- In Stack16, the picture is made of two parts: one containing the highest 8 bits (MSB) for each pixel, stacked on top of another containing the lowest 8 bits (LSB).
- Double-Width is similar, but the MSBs and LSBs are horizontally interleaved which is like Native, and it's faster. TODO: verify.
Syntax and Parameters
Accepts a 16-bit clip and returns a stacked 8-bit clip.
ConvertToStacked(clip clip ] )
ConvertToDoubleWidth(clip clip ] )
- clip clip =
- Source clip. Must be native 16 bit: YUV420P16, YUV422P16, YUV444P16, Y16.
Accepts a stacked 8-bit clip and returns a 16-bit clip.
ConvertFromStacked(clip clip, int bits ] )
ConvertFromDoubleWidth(clip clip, int bits ] )
- clip clip =
- Source clip. Must be YV12, YV16, YV24 or Y8.
- int bits = 16
- Bit depth of returned clip. Must match the original bit depth. For example,
## Decoding 10bit, YUV 4:2:0 source LWLibavVideoSource(<path>, stacked=true, format="YUV420P10") ConvertFromStacked(bits=10) ConvertBits(8, dither=0) ## '0' means on, '-1' means off
- Double-Width example,
## Decoding 10bit, YUV 4:2:0 source ConvertToDoubleWidth() F3KDB(Input_Mode=2,Input_Depth=10,Output_Mode=2,Output_Depth=10) ConvertFromDoubleWidth(bits=10) ConvertBits(8, dither=0) ## '0' means on, '-1' means off
