A60224

[edit] Description

a60224 is an inverse Telecine filter.

This filter measures the amount of horizontal stripes for each frame and selects the output frame based on that value.

Since the selection results before and after are not considered, the same result can be obtained regardless of the order of output.

Since the motion is not calculated, it will be jerky if used outside the 3:2 pulldown location. In fast mode, the calculation is thinned to 1/4.

[edit] Requirements

• [x86]: AviSynth+ or AviSynth 2.5.8 or greater
• [x64]: AviSynth+
• Supported color formats: RGB24, RGB32, YUY2, YV12

[edit] Syntax and Parameters

a60224 (clip, bool "fast", float "blur_rate", int "x1", int "x2", int "y1", int "y2")

clip   =

Input clip.

bool  fast = false

If fast=true is specified, fast mode is enabled.

float  blur_rate = 0.0

blur_rate is a value that indicates how much afterimage a frame leaves in the next frame.

3DNR it's there for capturing in a light environment, but you may not need it. Greater than 0.03

I don't think that you will get good results even if you specify a threshold value. The default value is 0.

int  x1 = 0

int  x2 = 0

int  y1 = 0

int  y2 = 0

If you specify x1,x2,y1,y2, the calculation will be done in the range where the top, bottom, left and right are cropped.

[edit] Examples

a60224 with default values:

MPEG2Source("telecine source.d2v")
AssumeTFF()
DoubleWeave()
a60224(fast=false, blur_rate=0.0, x1=0, x2=0, y1=0, y2=0)

[edit] Changelog

2004/03/15
- Crop of calculation range was in byte unit, so fix it in pixel unit

2004/03/06
- For Avisynth 2.5
- Ignore color signals
- Arguments x1,x2,y1,y2

2003/11/16-2
- Executed emms after GetFrame
   It can be used after an MMX routine that does not do emms like DeDotA.

2003/11/16
- Floating point error was checked.

2003/11/11
- Added blur_rate option

2003/11/03
- Removed extra parts that were only for the author's environment
- Added fast mode

2003/10/28
- Fixed a bug that the second half does not move

2003/10/26
- Fixed a bug that returned a frame that does not exist

2003/10/13
