Cant get rid of rainbows from this source
Usually Bifrost() or LutDeRainbow() work wonders, but no matter how strong I make these 2 by altering the parameters, the rainbows just will not come out of or reduce any in this source. I have also tried both before and after TIVTC.
Here's an untouched video sample to look at. https://mega.co.nz/#!cl4wELTS!RM43m7...iCqmlqzIkkAxcQ Any suggestions on why I haven't been able to remove them? |

Since you have just rainbows and not much dot crawl, try the following:
Code:
fft3dfilter(sigma=10,plane=3,bt=5) Reason: Rainbow removal filters rely on rainbow patterns alternating every frame, but here they're stable. Maybe it was already put through a comb filter, but either the filter was broken or the input was really horrific, and instead of removing them entirely it could only stabilize the rainbows. At first I thought they used a filter like Dup() to propagate the rainbows, but the chroma noise changes every frame, even if the luma noise is identical. Strange. |
