Well my goal so far is to just rewrite it in C++ so we have source and x64.
I want to use StaxRip with it. But StaxRip is x64 now. Already started to do it. So far I can tell that there is an error in documentation. Version 1.8.7 has mode = 1 by default. As stated in docs for 1.8.6: starting from 1.8.5 version: - new mode (mode = 2), which is using float precision for some calculations (best quality, now mode = 2 as default) But in code it is 1: Code:
.text:10011944 mov eax, 1 |

Halo effect around objects on bright background
I recently discovered HDRagc and have been using it on various videos from 16mm film. It's been great, but today I encountered a clip that yields a light colored halo around dark objects positioned on a bright background as shown in the attachment.
I have HDRagc setup with: HDRAGC(coef_gain=5.0, max_gain=9.0, min_gain=1.0, coef_sat=1.0, max_sat=9.0, min_sat=0.0, corrector=0.8, black_clip=0.000, avg_window=15, protect=2, shift_u=0, shift_v=0, reducer=0.0,avg_lum=128) I typically use the corrector at 1.0. I set it to 0.8 to enhance the halo effect so it shows up more clearly in my attached picture. I have tried various settings to get rid of the halo. I set corrector above 1.0 which reduces halo but oversaturates the white background. Turning protect on and off had no effect. Any idea why the halo appears and what to do about it? Thanks, Steve |

Hdragc aura
Hey it is possible the aura is caused by 2 sharpening filters if you add a blur this could solve the problem have a try.
example # Lanczos4Resize(1280,720) # Lanczos4 (Sharp) # Blur(0.40) # asharp(1.25,6,-1,false) # |

Hello,
An update would be really great. Do you have a dominant redness problem on your videos ?

Mournir, much better, but looks a little bit cyan-ish to me, little bit too much red removed [but my eyes are lousy].
Anyway post you mod for OP.

I thought I'de try in GamMac, see what happens.
Code:
SHOW=False RedMul1=1.00 RedMul2=1.06 LockChan1=1 LockChan2=LockChan1 Scale1=2 Scale2=Scale1 O = Imagesource(".\Halo effect with HDRagc.JPG")#.Crop(3,5,-6,-7) M = Imagesource(".\2005271449230088.jpg")#.Crop(3,5,-6,-7) G1= O.Gammac(Th=1.0/256,LockChan=LockChan1,Scale=Scale1,dc=O.Blur(0.2),redmul=REDMUL1,show=SHOW) G2= O.Gammac(Th=1.0/256,LockChan=LockChan2,Scale=Scale2,dc=O.Blur(0.2),redmul=REDMUL2,show=SHOW) O = O.subtitle("Original") M = M.subtitle("Mournir") G1= G1.subtitle("Gammac_1") G2= G2.subtitle("Gammac_2") T=stackHorizontal(O,M) B=stackHorizontal(G1,G2) StackVertical(T,B) click to enlarge As still a bit cyan-ish, applied a red multiplier, not as bright as Mournir, but a bit more balanced prior to maybe tweak by hand. There seems to be some kind of halo or aura around the little girl (extending far from her - see it best in original pic). EDIT: You could eg add args omin=5 omax=250 to gammac args to leave some tweaking lee-way [default is 0, and 255] EDIT: Maybe back-off on the redmul a bit, maybe Gammac2 looks too red again.

Test version 5 also does not like HDRAGC, need to revert to test version 2.
//EDIT// The brand new 3.6.1 test version 6 handles HDRAGC with flying colors, and I also did not find any older CPP 2.5 plugins which would cause crashes. Last edited by manolito; 4th June 2020 at 20:17. |

I have Hdragc working with MP_pipeline it gives a very nice fps boost this is in mode2 i don't think there would be much if any improvement if it was running a pure Hdragc x64.
i am running x64 avisynth+ with megui x64 i too still get the halo problem i am not sure what the cause is it could be that luma is getting too much gain i wish there was a way to have a limiter built in for over 128 tv levels there is too much gain at the top but the enhanced shadows do look good i hope this fps boost will help others. |
