假如是雜訊
If you have a very old and noisy source, you may try to clean it with some denoise
filters. The SpatialSoften plugin work quite well. Try different filters and values.
Code:
LoadPlugin("MPEG2DEC.dll")
LoadPlugin("AVISynth_Spatial.dll")
Avisource("capcap.avi")
# Crop(4,0,632,464) 看你的情形自行調正或啟用-切割
SpatialSoftenMMX(2,4,6,false,false,4,4,6,8)
TemporalSmoother(3,3)
SpatialSoftenMMX(2,4,6,false,false,4,4,6,8)
# BicubicResize(480,480) 看你的情形自行調正或啟用-重新定大小
