Color correction of VHS recordings
Calculated using Moth3r’s spreadsheet by recording a test card to a new blank VHS tape.
Panasonic DMR-EZ49V (PAL machine in NTSC mode):
ColorYUV(gain_y=11.11, off_y=3.34, gamma_y=-18.49, off_u=0.92, cont_u=27.20, off_v=0.83, cont_v=41.55)
JVC DR-MV5S (NTSC machine):
ColorYUV(gain_y=23.22, off_y=1.44, gamma_y=-14.03, off_u=2.21, cont_u=40.83, off_v=2.70, cont_v=22.24)
Remaining mean error <=3.
