Bad Pan Scenes

[-IRnoob-]

Hi Guys. I was wondering if you guys could help me out on this problem of mine. I use Decomb521, and i try to use the following code on my back ups of an old anime. I'm tring to keep the FPS to 29.97.

Code

AssumeTFF()
FieldDeinterlace(Full=false,threshold=115,dthreshold=7,chroma=true,blend=true)

But on my panning scenes the video moving from left to right or right to left jerks. It moves good for a couple of frames, but then it jerks and reapeats again. I've tried using the Telecide way but that gives me worse results. Any suggestion would be really great.

Well, trying to keep it at 29.97 FPS is the problem - most old anime was animated for 24FPS and then telecined to get to 29.97FPS for NTSC, so every pan will be jerky unless you apply inverse telecine (which means Telecide followed by Decimate) on it. All Telecide does is remove the combs, but it'll keep the duplicated frames that look jerky in the end - and that's what the Decimate after Telecide throws out.

np: Meat Beat Manifesto - Spinning Round Dub (In Dub)

I'll try that after i come back from work, thanks Leak.:)

Alright, the Telecide and Decimate makes the problem go away now. But i get some jagged edges in some scenes.

try raising dthreshold and see if the dancing edges go away (agressive decomb settings tend to cause this artifact). do note that as you raise dthreshold you will let more potential combs slip by.

Well, you could give my BlendBob script (http://forum.doom9.org/showthread.php?threadid=79144) a try; it shouldn't produce jagged edges when used with KernelBob (unless the KernelBob threshold is set too high) and it's not just for De-Rainbowing

Use it like this:

...
KernelBob(1,8) # or (0,8) if your material is bottom-field-first
BlendBob()
Decimate(...)
...

Also, there shouldn't be any combs that slip through (with mouth flaps for examples) but blends instead, which IMHO are less disturbing.

np: Slicker - We All Had A Plan (We All Have A Plan)

Alright guys, thanks for the suggestions. I will give a stab at it and see if it gives me better results.

Wow, the results got way better now, no more jagged edges and the panning is fluid as water. Thanks a lot guys, you have helped me out a lot.:)
