Syntax and Parameters

z_ConvertFormat

Scaling, colorspace conversion, and depth conversion.

z_ConvertFormat (clip clip, int "width", int "height", str "pixel_type", str "colorspace_op", str "chromaloc_op", bool "interlaced", float "src_left", float "src_top", float "src_width", float "src_height", str "resample_filter", float "filter_param_a", float "filter_param_b", str "resample_filter_uv", float "filter_param_a_uv", float "filter_param_b_uv", str "dither_type")


clip   =
Input clip.


int  width =
int  height =
Output width and height in pixels.


string  pixel_type =
Output pixel type ("YV12", "YUV420P16", etc.)


string  colorspace_op =
Colorspace operation description.
Format is "matS[:transS[:primS[:rangeS]]]=>matD[:transD[:primD[:rangeD]]]"
Example JPEG to MPEG: "170m:709:709:f=>709:709:709:l"

"2020" same as "2020_10"
see tables on VapourSynth resize documentation


string  colorspace_op =
Chroma location operation description.
Format is "[locS]=>[locD]"
Example JPEG to MPEG2: "center=>left"
Chroma location table:
  • "left"
  • "center"
Compatibility aliases
  • "dv" : left
  • "jpeg" : center
  • "mpeg1" : center
  • "mpeg2" : left


bool  interlaced = false
Whether to use interlaced mode (default: false)


float  src_left =
float  src_top =
float  src_width =
float  src_height =
Optional crop rectangle in the input frame.


string  resample_filter =
Resampling modes: "point", "bilinear", "bicubic", "spline16", "spline36", "lanczos"
Compatibility aliases: "gauss", "spline64", "lanczos4","blackman", "sinc"


float  filter_param_a =
float  filter_param_b =
First and second parameter to resampler.
Example Bicubic (Mitchell-Netravali): resample_filter="bicubic", filter_param_a=0.333, filter_param_b=0.333
Example 4-tap Lanczos: resample_filter="lanczos", filter_param_a=4


string  resample_filter_uv =
Resampling mode for chroma.


float  filter_param_a_uv =
float  filter_param_b_uv =
First and second parameter to chroma resampler.


string  resample_filter =
Dithering type: "none", "ordered", "random", "error_diffusion"
