I tested this new filter on anime ntsc material (cowboy bebop) and the result is really good, thanks
I've had only some problems on scenes where the camera slides: in those scenes telecide works better when in the rest of the anime BlendBob gives a far better result. In those scenes the result gived by BlendBob is not fluent at all and the and adiacent frames have great difference in luma. Am I using the wrong settings? Is there a way to automatically select in which scenes avisynth has to use a filter instead of another one? The code: Code:
f1= kerneldeint(a1,order=0, sharp=true, threshold=10) e1=separatefields(a1).trim(1,0).weave().kerneldeint( order=1, sharp=true, threshold=10) g1=interleave(f1,e1).BlendBob(derainbow=1, rainbowThresh=25).decimate()

@ leak:
compleeeetely off topic, but how do you get the "now playing" thing on your sig going? (some pretty cool stuff too)

bit of praise :)
just a mildly useless post to tell you leak, that I fobbed the filter on one of my friends, who had a nightmare of a dvd(looked some dodgy vhs reencode) to encode, with shimmering, bobbing, rainbows and so on(on top of it, it's a hybrid)..........he was very impressed it did a great job (I saw a few samples). The only thing is that there were so many rainbows that the output looks sort of washed out now, but that's another issue anyway . So, one more converted to blendbob!

Choice of Bob
I'm curious if any of you have experimented with different Bobs when using BlendBob? I have to admit,when I first saw this thread - I skipped some essential reading and jumped to the end of the thread for the final script and was left scratching my head wondering which Bob to use.
During my experimenting however I discovered that DGBOB(1) works very well (analogue captures) indeed. In fact I prefer it to KernelBob <--tried various parameters/versions. Has anyone else done any other comparisons? I'm just curious why KernelBob was picked initially. |

DGBob produces too much shimmering on anime sources for my tastes, but of course YMMquiteV on different sources. Anyhow, I'm back to getting my optimized KernelDeint done and out the door and after that I'll change (or rather add to) BlendBob a function to use KernelDeint internally for comparison only and weave the closest fields instead of blending deinterlaced versions of them; in that case it won't make much of a difference which smart deinterlacer you use... np: Underworld - Cups (Beaucoup Fish) |

I'll wait for the new version before jumping on the bandwagon, but after reading this thread I still have a doubt. From what I can understand, this filter has to be followed by decimation in order to achieve complete IVTCing. Is that correct?

This means that in a properly telecined stream you'll get one of the shifted fields matched with it's predecessor (which will match it better, unless there's absolutely no motion going on), so you'll also get a duplicated frame every 5 frames in the output (just as with Telecide), which Decimate will happily eliminate. What you shouldn't get is residual combing (unless your bobber did it's work poorly), as a blend of 2 frames made by deinterlacing fields can't introduce extra combs. np: Burnt Friedman & Jaki Liebezeit - Obscured By 5 (Secret Rhythms) |

Anyway, how feasible would it be for you to incorporate a decimating function and make this a full IVTC/derainbowing package with each function accesible separately? I know I'd love to have to use YATTA only for VFR encodes and not pattern matching correction. |

If you feed it 60 fields per second material, like a sport broadcast or similar, you will get ghosting, as there really are no matching frames, but it'll choose one of the two possible anyway. And by the way: is there some reason you always ask about each and every thing when just doing a small test would yield the same answers, and quicker at that? Quote:

I've been toying with DGBob and KernelBob in combination with BlendBob for the past few days against pure interlaced sources (NTSC). I can't seem to get around one issue - motion always appears more fluid when using DGBob than with KernelBob. I'd rather have KernelBob be my default/preferred option - esp with Leak's recent MMX optimizations (THANKS btw).
Can anyone help improve this? This is my script as it appears now: # HUFFYUV YUY2 Source AVISource("d:\capture\capture.avi") # Crop when downsizing to 352x480 from 720x480 Crop(8,0,-8,0) # Bob #DGBob(1) KernelBob(order=1,threshold=8,sharp=false) ConvertToYV12() BlendBob() #Denoise - added at the end for speed reasons alone. CNR2() UnDot() RemoveDirt() LanczosResize(352,480) Blockbuster(method="noise",variance=0.3,seed=1) |

I couldn't wait until the new version is released, so I tried the current one on my Spawn DVD. This filter is awesome, unlike Decomb or SmartDecimate there is no remaining combing and there's also no "color ghosting" as there is when blurring the chroma channel after Decomb or SmartDecimate. There are some jagged edges here and there and some minor ghosting, but overall the result is much more pleasing through the eye (at least when stepping through it in VDubMod). Here are the settings I used:

completely ignorant question: What's the equivalent of the following scripts to blendbob?
-------------- Telecide(order=1,guide=1) Decimate(mode=3,threshold=3) ---------------- Telecide(order=1,guide=1) Decimate(mode=1,threshold=3) ----------------- FieldDeinterlace() |

Sorry if this is a stupid question, but I only just recently discovered this wonderful filter! I was just wondering if LeakKernelDeint is still the preferred bobber to use with this? I tested the kernel mode in TDeint with blendbob, and the result was a little more compressible than with LeakKernelDeint, though it was a lot slower. Visually, I couldn't really tell much difference between the 2. There are a couple other modes in TDeint that I couldn't really tell much difference between either.
Should I just stick with LeakKernelDeint for its nice speed, or does another method offer some advantages that I might not be seeing? Source is anime, by the way. |
