Looking over the blended Alisia Dragoon TAS again, I notice there are parts where the flicker appears as it does in game, but much of it where it does not. Between 7:50 and 8:20 of the encode, the flashing of the charged Thunder in the top left looks correct. Would there be any way to find out what is different to the rest of the video where there is more blurring there, and apply it correctly throughout the encode? I suspect getting the right timing would also fix the flickering on enemies that warp in, as well.
AVISource(...)
shifted = DuplicateFrame(0).Blend_67_33
Blend_67_33
Replace(100, 200, shifted)
# ...
function Blend_67_33(clip c) {
c
Layer(SelectEven, SelectOdd, level=round(1.0/3.0 * 257))
}There is one problem with TASBlend. It increases jerkiness.
original = AVIsource("test-blend.avi").pointresize(256,448).killaudio()
even = original.selecteven()
odd = original.selectodd()
maskclip1 = ImageReader("blackwhite-test.png",1,10000,30).pointresize(256,224)
maskclip = stackvertical(maskclip1, maskclip1)
temp1 = even.overlay(odd, mask=maskclip, opacity = 0.7)
temp2 = odd.overlay(even, mask=maskclip, opacity = 0.3)
return interleave(temp1.selecteven(), temp2.selectodd())
Someone on IRC had the following idea: take odd lines from frame 1, merge with even lines from frame 2 ---> frame 1 take even lines from frame 3, merge with odd lines from frame 4 ---> frame 2 ... and so on. I tested how it looks like, but it wasn't good. I did the following: take line 1 from frame 1, line 1 from frame 2, line 2 from frame 1, line 2 from frame 2, line 3 from frame 1, line 3 from frame 2, ... -> frame 1 take line 1 from frame 4, line 1 from frame 3, line 2 from frame 4, line 2 from frame 3, line 3 from frame 4, line 3 from frame 3, ... -> frame 2 (blackwhite-test.png is a 1x224 picture consisting of a white pixel followed by a black pixel followed by a white pixel followed by a black pixel ...) That's the AVIsynth code to do that (given the input video is 256x224)What do you think about the result for 70% / 30% or the result with 100% / 100% with deinterlacer ?original = AVIsource("test-blend.avi").pointresize(256,448).killaudio() even = original.selecteven() odd = original.selectodd() maskclip1 = ImageReader("blackwhite-test.png",1,10000,30).pointresize(256,224) maskclip = stackvertical(maskclip1, maskclip1) temp1 = even.overlay(odd, mask=maskclip, opacity = 0.7) temp2 = odd.overlay(even, mask=maskclip, opacity = 0.3) return interleave(temp1.selecteven(), temp2.selectodd())
EDIT:
Now blinking totally depends on what frame it starts at. It may appear almost invisible in some places of the movie and good in others.Edit: I think I understand now: It's my avatar, isn't it? It makes me look angry.
And here's a comparison of another problematic place.
Keep bottom looks the same at any ratio:
Keep top with 0.7:0.3 ratio:
And finally with 0.5:0.5 rastio:

return (c.Height==yRes) ? c : ((c.Height % 2) == 0) ? c.AddBorders(0, 0, 0, 1, $FFFFFF).Add_BlackWhiteLines(yRes)
\ : c.AddBorders(0, 0, 0, 1, $000000).Add_BlackWhiteLines(yRes)
}So this is the first time I see the blurrying caused by TASblend. I think my simple 25 FPS solution was better since it was almost unnoticeable.
I've defaulted to using TASBlend on all of my new encodes regardless to flicker.
