Remove Rainbow DBZ

[Eevee]

Hi Greetings This is my Post SO be Kind
am just new in Avisynth Usage and Encoding
am trying to remove rainbow
http://forum.doom9.org/attachment.php?attachmentid=14469&stc=1&d=1416123866
I want like this
http://forum.doom9.org/attachment.php?attachmentid=14468&stc=1&d=1416123866
am using this script
converttoyv12()
Blur(1.0)
org = last
org_u = utoy(org)
org_v = vtoy(org)
msharpen(threshold = 10, mask=true)
reduceby2()
greyscale()
uv = blur(1.5).levels(0,2.0,255,0,255).blur(1.5)
filtered_u = org_u.blur(1.5).blur(1.5).blur(1.5).temporalsoften(2,255,0,3,2)
filtered_v = org_v.blur(1.5).blur(1.5).blur(1.5).temporalsoften(2,255,0,3,2)
u_final = MaskedMerge(org_u, filtered_u, uv)
v_final = MaskedMerge(org_v, filtered_v, uv)
ytouv(u_final, v_final, org)
lanczosresize(640,480)
tweak(sat=1.1, cont=1.2)
hqdn3d(3)


but did not work
Thanks in Advance

hi, bro, just read ur post via my latest univeral ("univeral" literally) translator, :D
and back on track
rainbow is a toxic bitch artifacts
dont put too much faith on some imaginary magic filter that gets rid of this crap perfectly

[feisty2]

downsizing chroma did great jobs (comparing to other derainbow methods) on very rainboweeey clips i remember

[feisty2]

a very weird idea just popped outta my head
maybe just discard the original chroma and reconstruct it completely?
first, separate luma out, clearly it's the one and only plane free from rainbow mess
then convert the rainboweeey source clip to rgb and use "colorlike" filter to get the overall color hints of every r, g, b channel
now, apply those hits on luma plane again by "colorlike" to reconstruct a new rainbow free rgb clip
then u can convert it to yv12 or just keep that way

ytouv(u_final, v_final, org)
I don't understand :confused: will be nice if you give me a example
:)

Can you share a part from source? Then people would help you for rainbow removing script.

I mean a part as a few second sample from the source that have problem, cut by dgindex or some other program that doesn't re-encode the video.

[lansing]

I honestly didn't see any rainbow in your picture, can you point out where it is?

[Overdrive80]

You should read rule 6) of forum.

See this thread http://forum.doom9.org/showthread.php?t=169758&page=2

In my view rather than eliminate rainbows which seeks to improve the contrast, that is, the black is really black (see hair of Gohan) and so on.

Eevee, test to start the following:
Levels (16,1,235,0,255, coring = false)

You can also play with the Tweak function, searches in Avisynth manual how to use these functions.
