Let's play deblocking
Hi there. Here I bring you some footage that needs deblocking, and I would like you to give me a hand. Of course that I have searched for other deblocking posts in the forum. Specially this, from which I have tried some scripts, and have found some improvements. But still I think I could get better results.
Here is a video sample. It is an anime movie with low compression artifacts, which become very noticeable and unpleasant after sharpening. But for this very same reason I think it should be possible to remove them, at least a bit. It seems to be that most of the deblocking filters I could find are not effective against this problem. Therefore I appeal to your large knowledge and experience to see if there is a solution. Here are some functions I have tried up to now: Code:
#Source video size is 480x360 Spline64Resize(384,288) ASharp(0.0,10.0) Spline64Resize(960,720) ASharp(32.0,0.1,-0.9,true) PointResize(480,360) Code:
QTGMC(InputType=1, Preset="Medium", EzDenoise=1.5) gradfun3() Code:
DeHaloH() RemoveDirtMC_SE(gpu=false,twopass=false,clmode=0) funkydeblock(quant=10) mc_spudsmod(frames=3,starfield=true,chroma=true) dfttestMC() GradFun3() After deblocking, I usually add FFT3DFilter(Sharpen=1.0, sigma=5.0, interlaced=false) to make the drawing look better. I have also tried MSU Cartoon Restore filter, which appearently does what I am looking for, but actually makes the video look low-bitrated. And as I am trying to "restore" the source, I cannot accept that. Here I give you some snapshots of the raw video: And then it becomes like this after sharpening (+ other fixes): Thank you very much. UPDATE: I have found this to be extremely useful for what I am looking for: Code:
mc_spudsmod(frames=4, strength=2, starfield=true, anime=true, chroma=true, aggressive=false, gpu=true) Toon(strength=0.6) LSFMod(strength=50) AAA() FFT3DFilter(Sharpen=0.5, sigma=2.0, interlaced=false) Last edited by magiblot; 8th September 2016 at 01:21. |
