Solar Curve

• VapourSynth implementation of solar curve in RGB24 & RGB48 colorspace, with idea from Easy Compare
• Filter function: y = 127.9999 * sin ( A * x ^ 3 + B * x ^ 2 + C * x - π / 2) + 127.5
• Function parameters from Easy Compare. See its plot on Google
• Takes YUV clip input and returns a YUV clip
• Don't use this filter too much if you are a sensible encoder. TRUST YOUR OWN EYES!!

Usage:

import solar
output = solar.solar(clip)    # conversion in RGB24

or

import solar
output = solar.solar48(clip)  # conversion in RGB48

Result: Before | After
