Hi,
I've been working on a DVD5 clip, actually a VHS > DVD clip for weeks now trying to get the brightness, hue, luminance, and contrast "correct". Problem is that I work on it on my PC monitor, burn a sample to DVD RW, play it on my standalone DVD player through the TV, and everything I do is subjective instead of objective.
I've used vdubmod, avisynth, vdub, tmpgenc xpress, tmpgenc plus, cce, and everything else I can find with nothing but hit or miss results. So far, all misses.
I've got copies of Doom9 Postprocessing video with Avisynth, and vdubmod, Capture Guide, and about 100 others.
Is there a concise cookbook type recipe article that will help me establish the color values?
Here is a copy of the most recent *.avs file; you can see from the commented out lines some of the things I've tried(don't include the filters used in TMPGEnc Xpress).
***BI001.avs***
# use avi with sound
AVISource("BI001_1.avi",true)
# use avi without sound
# AVISource("BI001_1_Movie.avi",false)
LanczosResize(720,480)
# ColorYUV(levels="PC->TV")
# ColorYUV(off_y=-30, gain_y=120)
# ConvertToYV12()
# Histogram()
# Set the gamma levels
# Levels(0, 1.313, 255, 0, 255)
# levels(16,1,235,0,255)
# Tweak the color, brightness, contrast
# Tweak(hue=20, sat=3, bright=90, cont=1.2, coring=false)
# remove the commercials
# Define "clip"
clip=AVISource("BI001_1.avi")
trim(clip, 50000, 58329)+trim(clip, 69472, 80000)
Anybody got any ideas how to cut to the chase?
Thanks in advance.
Cheers!
