Description
A purely spatial dot crawl removal script for AviSynth+. Only the luma channel is processed, chroma is simply copied. DDCR stands for Didée's Dot Crawl Remover.
Modified from here.
Requirements
- [x86/x64] AviSynth+ v3.7.2 or greater
- Supported color formats: all 8-bit Y/YUV colorspaces
Required Plugins
Latest versions of the following filters are recommended unless stated otherwise.
Syntax and Parameters
- DDCR (clip input, int "mode", float_array "frfun7_params")
- clip c =
- Input clip; all 8 bit Y/YUV colorspaces are supported. Progressive input only.
- clip c =
- int mode = 1
- Processing mode:
- 1 : post IVTC
- 2 : post deinterlacing
- Filter should be used right after IVTC or deinterlacing.
- With truly interlaced content, QTGMC does a good job at removing most of the dot crawl, mode 2 helps remove the remaining dot crawl.
- Processing mode:
- int mode = 1
- float_array frfun7_params = [1.01, 8.0, 1, 0, 3]
- frfun7 parameters, they must be given in the correct order.
- lamda (float) : adjust the power of the local denoising.
- T (float) : limits the max luma denoising power for edges.
- P (int) : 0 is faster but lower quality, 1 is slower but better quality.
- TP1 (int) : threshold which affects P=1.
- R1 (int) : first past radius; valid values are 2 or 3.
- If only the first value is given, the rest will be set to their default, and so on. See frfun7 documentation for full details.
- frfun7 parameters, they must be given in the correct order.
- float_array frfun7_params = [1.01, 8.0, 1, 0, 3]
Examples
DDCR with default settings:
AviSource("Blah.avi") TFM(pp=0) TDecimate() DDCR(mode=1, frfun7_params=[1.01, 8.0, 1, 0, 3])
