Which is better for calibrating the levels of a clip in Avisynth, the histogram or ColorYUV(analyze=true)?
Because even if I stretch the luma 245 with ColorYUV, the graph does not enter the brown portion.
I thought the brown parts of the histogram graph are from 0-15 and 236-255?
This is the Avisynth script I used for the attached pictures.
Code:
AviSource("1995.avi")
AssumeTFF()
Crop(8,0,-8,-8) # crop vhs noise and black borders
#ColorYUV(analyze=true)
#ColorYUV(off_y=-6, gain_y=16)
#ColorYUV(analyze=true)
ConvertToYV16(interlaced=true)
histogram(mode="levels")
