Hello,
I am having some trouble with color matching the LD footage to the BluRay footage. In Part 1, two shots need to be inserted from LD to BluRay footage.
- The full shot of the wife yelling “No” twice (this shot is faded out on BluRay).
- The “IT” writing on bathroom wall shot with “To be continued” title card.
I used AviSynth and the script ColourLike to create two histograms:
- from the beginning of the wife yelling scene
- from the previous shot of the “IT” writing on the wall.
The first shot works quite well.
BluRay footage: http://www.thehutt.de/it/02_blu.png
LD footage (upscaled + added noise, no color correction): http://www.thehutt.de/it/02_ld_nocorr.png
LD footage (upscaled + added noise, color correction): http://www.thehutt.de/it/02_ld_corr.png
However, on the final “IT” writing, I have some trouble. The histogram I lifted from the previous “IT” writing (a couple of shots before) and it looked quite okay.

However, if I apply this histogram to the final shot missing on the LD), there are some unwanted artifacts. Also, as this shot ends in a fadeout, applying color correction here results in some really weird artifacts (especially where the black isn’t actually black).

Here is the AVS script I am using (for the final shot which has these problems):
Import(“d:\Anwendungen\Multimedia\AviSynth\plugins\QTGMC\QTGMC-3.32.avsi”)
AviSource(“d:\video\It\EndofPart1DV.avi”, fourCC=“CDVC”)
AssumeBFF()
ConvertToYV12(interlaced=true)
QTGMC( Preset=“Slower” )
Pulldown(0,3)
Trim(2237, 2484)
Crop(12, 0, -4, -0)
eedi3_rpow2(rfactor=2, cshift=“spline36resize”, fwidth=1440, fheight=1080, threads=1)
AddGrain(10)
AddBorders(240, 0, 240, 0, $000000)
ColourLike(“d:\video\It\IT_1a_hist_s.txt”, “d:\video\It\IT_1b_hist_s.txt”)
So my question is: is there a way to make ColourLike work even with the fadeout? Or are there any better alternatives?
