deinterlacing & hdragc issues
hi guys,
i'm having problems properly deinterlacing & using hdragc on a terrible source (movie: Vivah ...2006 release...dvd9 region free) i'm attaching my script below & also links for dvd9 sample & my test output. DVD9 sample: http://maxupload.com/0753B0AF test # 2 output: http://maxupload.com/853F7B86 script: SetMemoryMax(1024) DGDecode_mpeg2source(MOVIE,cpu=2,info=3) ord = last.getparity() ? 1 : 0 leakkernelbob(order=ord,threshold=5,map=false) RePal() Vinverse() ...other script here HDRAGC(min_sat=0.0,max_sat=2.0,coef_sat=1.15,min_gain=0.0,max_gain=1.0,coef_gain=.1) ...other script here related to HDRAGC crop( 2, 62, -6, -62) Lanczos4Resize(704,304) aux=DeGrainMedian(mode=0, limity=7, interlaced=true) VagueDenoiser(auxclip=aux,wiener=true) ...sharpening... ------------------ in the test output, you'll see green frames...then regular output...i'm scratching my head as to why. if i can get some suggestions, would really be helpful. - Farooq Last edited by EuropeanMan; 1st August 2007 at 18:26. |

Just serving with DGDecode and no other filters...I get no green frames. So start adding the filters one-by-one until the problem occurs. Then you will know which one is at fault. I can't help you with the blended fields because I hate that damn stuff and won't spend even a second bothering with it.

About deinterlacing, in the past I used SmartDeinterlacer filter, but the threshold needed to be only 7 and even then the picture had those typical small left-behinds on some places, especially darker ones, and also, the overall picture was not 'calm' - i.e. an always present 'background' clutter.
So at some point, I used the filter only for stills, and used the common deinterlacer, blending the two fields together. But sometimes, the 'interlacing' is restorable, the telecide filter. Alot series/movies can so be deinterlaced without any vertical resolution loss. But, I see alot material that seem to have occasional (ex 1 out of 5) intact frames (no artefacts), and where the telecide filter works for more, but still outputs so many interlaced ones that it is still far from an option to use it for video. Also, it occurs (but very very rare) that, playing with Smart Deinterlacer's Advanced Processing settings, restores the original frame everytime, sometimes even in combination with telecide. So I started to wonder: when frames regularly have no interlacing artefacts, would it be possible that some more complex field/frame manipulation (with Avisynth) can reconstruct all frames to original? And if that is the case, are there known manipulation sequences that are likely to reconstruct most material? Or are there so many possible messing up reasons and ways that it's mostly a waste of time or the amount manual work to try to find it out isn't worth it? |

Ok I think I have solved the deinterlacing issues now.
However, I am using a different HDRAGC command line now with different parameters that is refusing to work because: HDRAGC(B,avg_lum=1078,mode=2,passes=4,shift_u=-15, shift_v=6,protect=2,coef_gain=0.22,max_gain=4.0,corrector=0.8,reducer=1.1,avg_window=30,black_clip=0.3,min_sat=0.4, max_sat=16, coef_sat=1.0) passes, shift u & v, reducer are NOT recognised for whatever reason...it errors out in AVSp. Why? I have version 1.8.7...of agc! |
