avisynth settings for hellsing?

ok, ive tried various things to get rid of the little horizontal lines that im assuming are from interlacing in the hellsing footage that im attempting to use. im getting fed up with avisynth on this. since there are a couple hundred hellsing videos on the site, i thought it would be safe to assume that someone would know the settings i need to use to elimate those annoying lines without screwing up the framerate beyond recognition

Are you using AVISynth 2.0 (came with the old AMVapp) or 2.5?

If you're using 2.0, try this (it usually works for me):

Telecide()
Decimate(cycle=5)
AssumeFPS(24) # only if editing in Premiere

im in 2.5, and it requires a parameter for telecide- its sooo annoying, but the amv app version wouldnt work at all

Hellsing is a relatively recent show, so I don't know if it'd be telecined. You need to step through the video to see if it really is telecined before applying an inverse telecine function.

If it is telecined, then follow the Decomb 5 tutorial for instructions on how to determine the correct field order. Most DVDs are top field first (so you'd use Telecide(1)).

If you want to replicate the behavior of Decomb 4, use
Telecide(order=[determined order], back=2)

to always consider the previous frame. Beware: this can cause jerky motion.

If you were using amvapp 2.0 you could use checkfieldorder() but it's not out yet so you'll have to wait

If you are using decomb 5.10 and the field order is top field first then the IVTC portion should look something like this.

telecide(order=1,post=0)
decimate(5)

In the meantime:

Code: Select all

function checkfieldorder2(in)
{
	tff = AssumeTFF(in).SeparateFields()
	bff = AssumeBFF(in).SeparateFields()
	StackVertical(tff,bff)
	Subtitle("Use telecide(1) if motion is smooth", x=20, y=20)
	Subtitle("Use telecide(0) if motion is smooth", x=20, y=Height(tff) + 20)
}

a = AVISource("..")
checkfieldorder2(a)

I don't know if the amvapp script actually does some image analysis to recommend a field order, but this should work to get you started :)

corrans solution worked. thnx all! i was assuming interlaced because in certain parts, the dark areas (like alucards hair) break up into those annoying black lines- but that solved it. thnx again!

Trythil, my script is almost identical:

Code: Select all

function CheckFieldOrder(clip c) {
sourcevideo=c
TFF=sourcevideo.AssumeTFF().SeparateFields().subtitle("Top Field First, if motion is smooth use Telecide(order=1)")
BFF=sourcevideo.AssumeBFF().SeparateFields().subtitle("Bottom Field First, if motion is smooth use Telecide(order=0)")
StackVertical(TFF,BFF)
}

It's much much more reliable than an automatic method.
