Hi there.
I'm trying to give to my work the best possible quality. Therefore I started using Avisynth and although I'm a noob at it I can tell the difference right the way when it comes to picture quality.
I'm working on an anime that was captured from old VHS recordings, and I must say that its quality is horrible. On top of that, the episodes have been already enconded with Divx 5.11 at 900k. In other words, I'm trying to re-encode something that has been already encoded.
Well I have tried to apply avisynth a lot of times and I keep running into one big problem all the time...
This is the script I'm currently using to improve the picture quality:
LoadPlugin("VagueDenoiser.dll")
LoadPlugin("Convolution3DYV12.dll")
LoadPlugin("EDeen.dll")
AVISource ("Ep2.avi")
Crop(4,8,0,-4,true)
Lanczos4Resize(640,480)
VagueDenoiser (threshold=5.5,method=1,nsteps=6,chroma=true)
Convolution3d (preset="animeBQ")
edeen(4,4,6,1,1,true)
Although the picture quality looks really good, specially thanks to vaguedenoicer, I can't get the movie to run smothly once I have fast-encoded it. The frames look all really skippy or ghoshy. I have tried taking some filters off or reducing the strenght of vaguedenoiser, but the problem is still there. I even tried adding new plugings, such as temporaldenoicer or Cn2 but they were to no avail. And also, I tried encoding again after frameserving it, but it is still the same.
After trying re-encoding my episodes with Xvid all the time, I switched to VP6.2 and I got and even better picture quality and a smaller size with this new codec, and once again I tried frameserving the episode into avisynth, but guess what? I kept getting the same problem. But this time the picture quality was even better due to the included sharpening filter and denoising filter that VP6.2 has.
Running out of options I opted to take a look at avisynth itself and I did the following:
AVISource ("Episode.avi")
I just wrote that to check if avisynth was the problem and guess what? IT IS! Just by frameserving the episode with avisynth I was still getting the same frame skipping and goshing.
Does this means that there is a bug in the program? Or maybe there is some kind of compability problem? :scared:
These are the details of my work :D
Original picture: Divx 5.11 at 900k

Re-encoded picture: VP6.2 Sharpness +10, Noise reduction +6, One Pass - Best Quality, 900k, RGB brightness-Contrast-gamma virtual Dub external filter, and then frameserved with Avisynth VagueDenoiser-Convolution3DYV12-EDeen.

Of course as I said before, After using avisynth the motion of the anime gets seriously impared. HELP PLEASE! I don't want to stop using avisynth. Look at the wonders that it has done to my anime :)
