Encoding: Fieldblended PAR Source

incredible · #1 10-06-2005, 04:19 PM

EDIT: .... Splitted from another thread

DONT do force a simple deinterlacing on combed material if its shure that the source wasnt a "Video" but a "Movie" when it has been shot!

First try ...

dgdecode_mpeg2source("xxxxxxx.d2v")
Telecide(order=1,guide=2,post=0)

By this you first try to inverse a dynamical phaseshift. Dynamical Phaseshifts do also result in combs).
If just deinterlacing a phaseshifted material this could/will end up in blends!

If the above line still ends up in combs, then ..... Restore24() at doom9 forum (search) or finally if that also doesnt help ... encode it as interlaced!

The SexInTheCity Vol1. Episodes DVD was very easy to restore to 25fps progressive by using the simple line above.

Hi,

<OT>I'm trying to convert this movie since more than one year. It has been called a "beyond repair" PAL movie in a lot of forum (just look at "spirited away" PAL version), because of all this blurring and frame generation, resulting in non smoothing movement.
The frames sequences, from a simple dgbob, of a panning sequence gives you:

Code:

FRAMES nº 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69
CONTENT   A  A  B  B  C  C  D  D  E  E  FG G  H  H  hIj J jK K  Kl L  lM M  Mn N  No O  Op P  Pq Pq Q  qR
RESTORE   A     B     C     D     E     F  G  H     I   J    K     L     M     N     O     P        Q

So a simple R24 don't restore correctly the framses (it's a FILM -> NTSC "video" -> PAL very bad conversion).
From my actual experience, the best script seems to be

Code:

LeakKernelBob(order=1, sharp=false, twoway=false, threshold=4)
tdecimate(mode=2,rate=23.976)
Lanczos4Resize(688,448,31,30,660,516)

LRemoveDust_YV12(17, 3)

Addborders(8,16,8,16)

Resulting in almost smooth movement.
</OT>
I think it's a long topic, that can be split from the PARanoia topic !

You should ask about this issue on doom9 forum, as scharfis_brain and MoMonster do have the biggest skills on this.

How do you obtain this info :

Code:

FRAMES nº 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69
CONTENT   A  A  B  B  C  C  D  D  E  E  FG G  H  H  hIj J jK K  Kl L  lM M  Mn N  No O  Op P  Pq Pq Q  qR
RESTORE   A     B     C     D     E     F  G  H     I   J    K     L     M     N     O     P        Q

?

scharfis_brain is the one that said it was beyond repair...

using a 'simple' script (with dgbob), and looking for a moving scene. Wit hvirtualdub, you quickly see what fileds are each one (in my previuos post, frame shoud be field, as it's the result of dgbob).

If you wan't, I can post pictures of 47, 48, 49 and 50 fields

Not necessary, I thought you had a programm that does that

But you can post them for people information if you wish.

Hi,

It's not easy to do this kind of program, otherwise, it would have been easy to convert back this 'shit' to 23,976 fps
