What is the origin of this clip - Do you have the original camera source ?
-
try something like this:
AVISource("snippetOfDark.avi")
hdragc(coef_gain=10.0,max_sat=3.0,protect=2,shadow s=true,corrector=0.8,reducer=1.6)
ConvertToYV16(interlaced=true)
SpotLessUV()
ConverttoRGB32(matrix="rec709",interlaced=false)
LoadVirtualDubPlugin("C:\Program Files (x86)\Virtualdub\plugins32\ccd_sse2.vdf", "CCD", 1)
CCD(7,1)*** DIGITIZING VHS / ANALOG VIDEOS SINCE 2001**** GEAR: JVC HR-S7700MS, TOSHIBA V733EF AND MORE -
Attaching another virtualdub2 cut of the same material - not packed with h.264. Extension of original file is .MTS and virtualdub2 says it can't cut without processing. Including no audio.

thanks, looks promising. So hdragc can run on 32bit computers only? And I found script to use for SpotLessUV.avsi here, am i correct?: http://www.digitalfaq.com/forum/video-capture/11408-horizontal-chroma-noise.html And the last plugin is for removing noise? Can run it separately only. Still have a feeling all that was used by a creator (-s) of Auto Levels.

So yeah, I experimented in comparing your script and Auto Levels plugin. After all I found I can't configure Auto Levels plugin quickly and there would be much of time loss on trying this. Also I remember Auto Levels is not dynamic and hdragc is. So I think I'm about to fight dark with your script now, good sir, thank you. (Still not managing to start ccd_sse2.vdf in one session so gonna trust Neat Video instead).

Manual gain/gamma:
Code:LWlibavVideoSource("snippetOfDark.avi") Trim(6,0) ColorYUV(gain_y=400, off_y=-55).ColorYUV(gamma_y=200).ColorYUV(cont_u=500, cont_v=500)

The big blob of white in the background (projection screen?) is throwing off the calculations of any auto filters. Either adjust manually as was mentioned, or mask out the white while auto adjusting.

@jagabo: nice,good catch!

Good job, but since that is a fragment of long video, dynamic thing like hdragc is needed.

It will only work for that one shot;
Code:mask = Crop(0,0,-1120,-680).AddBorders(0,0,1120,680).mt_binarize(70).mt_expand().mt_expand().mt_expand().Blur(1.4) Overlay(last, ColorYUV(gain_y=-240, off_y=20, cont_u=-240, cont_v=-240), mask=mask)
