I spent many ours trying to get good results of of old hockey record, but still without success. Maybe somebody will have time as to look at the sample and will help me to write good Avisynth script.
The source is VHS (interlaced mpeg2 PAL 720x576 25i)
The result I want is mp4 (x264 640x480 50p)
The problems are:
1. much noise and flicker i can't cope with
2. Some of the video are bright, some dark, I can't find out what brightness and contrast to use.
3 Red Russian jerseys looks almost totally desaturated, blue Finnish colors are rather bright.
4. Clip has a yellow tint I want to get rid of. Can be seen in the second part of the sample.
What I tried:
mpeg2source("Sample.d2v")
Yadif(1,1)
#colorYUV(autogain=true, autowhite=false) #don't like the result
#DeFlicker(scene=30) # doesn't work. Vdub analog doesn't help (some grey transitions and so on)
crop( 16, 6, -10, -12)
LanczosResize(640,480)
#HDRAGC(avg_lum=80, min_sat=1.0, max_sat=1.0, min_gain = 3.0, coef_gain = 4.0, shift_u=1) # don't know how to use this filter so didn't received anything good
Tweak(0,1,10,0.10,true,false) #Can't fint parameters, because video is different. First part of sample is bright, last is dark.
Sample: 52s (26Mb)
