This weekend i tried to back up a dvd using MencodeMe for the first time and the results weren`t that good. I think MencodeMe didn`t work for me yet or it`s just all my fault.

I followed the guides step by step and honestly i don`t know what else can i do. I even tried with and without avisynth. Is there really any chance of MencodeMe achieve the same quality as TMPGenc does? I can`t see how!

I even tried to increase the bitrate by lowering the duration of the file. Yes, my real file duration is 99 minutes and i put it around 83 minutes in order to reach a good 2500 kbps bitrate.
It didn`t move forward! My picture was still very blocky.

My source was a concert dvd i own: U2 - Rattle & Hum(198 - 29.97fps(100% interlaced)#has a few scratches but plays fine;

*used 1pass, never tried 2pass;

Please, someone help me?!

Hi:
First at all, good quality is obtained with mpeg2 2 pass.
Take following in account:
NTSC: If it's a hard telecined VOB, you must select framerate 23.976 and IVTC.
If it's interlaced, you must select deinterlace with the correct field order.
Interlacing encode not support yet.
NTSC: If it's soft Telecined you must select output 23.976.
PAL: You must select the correct frame rate (25) and set the deinterlace options with the correct field order is needed.

I`ve also used mpeg-2, 1-pass and the quality was even worse!
Have yet to try 2-pass!

How do i check if my source is a hard telecined vob?
Then how do i find the correct field order?

well, you mean that if i have a framerate of 29.97fps i must change it to 23.976 ?? But that won`t cause any stuttering? Jerky playback?


Thanx for the reply!

Most concert footage is pure interlaced video so you'll have two options: deinterlace and encode at 29.97fps or use MVConvert60ito24p and get a progressive 23.976fps output.

Here's the main function:

Code:
function mvconvert60ito24p(clip x, int "mode")
	{

	mode = default(mode,2)
	mbl=0.1
	
	ya=x.mvinterpolate(nb = 4,bl = 0.5-mbl, el = 0.5+mbl, wf = "hat")
	yb=x.duplicateframe(1).reverse().mvinterpolate(nb = 4,bl = 0.5-mbl, el = 0.5+mbl, wf = "hat").reverse()
	y=overlay(Ya,Yb,opacity=0.5)
	interleave(y,x)
	mode0=selectevery(5,2)
	mode1=overlay(selectevery(5,3),selectevery(5,2),opacity=0.5)
	mode2=overlay(overlay(selectevery(5,1),selectevery(5,3),opacity=0.5),selectevery(5,2),opacity=0.3)
	mode3=overlay(overlay(selectevery(5,0),selectevery(5,3),opacity=0.5),overlay(selectevery(5,1),selectevery(5,2),opacity=0.5),opacity=0.5)

	(mode==0) ? mode0 : (mode==1) ? mode1 : (mode==2) ? mode2 : mode3

	}
And here's KernelBob():

Code:
function kernelbob(clip a, int th)
{	ord = getparity(a) ? 1 : 0
	f=a.kerneldeint(order=ord, sharp=true, twoway=true, threshold=th) 
	e=a.separatefields.trim(1,0).weave.kerneldeint(order=1-ord, sharp=true, twoway=true, threshold=th)
	interleave(f,e).assumeframebased
}
Copy-paste both of them in Notepad for example and save to your plugins folder with the extension .avsi so you don't need to load them in your script whenever you need them.

You'll also need to download KernelDeint.

Usage is simple:

MPEG2Source("path\clip.d2v")
KernelBob(7)
MVConvert60ito24p()

This should give you a smooth progressive stream. You can of course do all the filtering after the functions.
