PAL Source

[mtamimi]

I have this PAL DVD which I got from AMAZON. it seems as if every fram is interlaced....

I tried
LoadPlugin("C:\Program Files\dgmpgdec148\dgdecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\TomsMoComp.dll")
mpeg2source("main movie.d2v")
tomsmocomp(-1,5,1)
Crop(10,2,-12,-18)
Lanczos4Resize(688,512)

The picture looks clean....I need your advice about the numbers I passed to the tomsmocomp function....can I always use them? How can I know if these are the best values?

thnx,

Well, what is the actual content of the disc? Or it's name, for that matter?

Things like sports or some TV shows are interlaced, even in PAL land; while movies usually are not.

Your video could be phase-shifted PAL, though - that's when the odd and even field of a frame are stored in adjacent frames; looks perfectly fine on TV, but like interlacing on a PC.

SeparateFields().Trim(1,0).Weave()
(Disclaimer: off the top of my head, so it might be wrong)

should fix it, or a simple

TFM()

if you have TIVTC installed.

np: Donnacha Costello - Opal Sessions Unreleased (Colorseries)

Thnx for the quick reply....
SeparateFields().Trim(1,0).Weave()
did not solve the problem...
tomsmocomp(-1,5,1)
did the trick....what does this mean regarding your guess that it could be phase-shifted PAL....the DVD is old

Format: PAL
Region: Region 2 ( DVD formats.)
DVD Release Date: 2001

Do a separatefields() or bob() and check in Virtualdub whether two consecutive frames are then (nearly) alike or are they all different. Easiest to see in a scene with a fair amount of motion in it. If the fields are all different, this is pure interlaced video in question. Just "PAL" or "Region 2" does not tell this.

thnx

I did use bob() and observed the movement of one of the actors ...every frame is different than the other...?

so it is real interlacing. you got 50 fps.
this means super fluid movements.

if you deinterlace to 25fps, you'll introduce motion stutter.

As always, a good way would be to cut out a small sample (select range in DGIndex -> "save & demux video") and upload it to a filehoster. Looking at the actual content is the easiest way to judge it.

Since it's PAL content that shows combing, it could be true interlaced (unlikely for a *movie*, but possible), or it could be some fieldblended normconversion stuff (very likely, alas.)
If it's really a normconversion, there are better ways of handling than "normal" deinterlacing. (Well, except for the FUBAR conversions that are out there, too.)

edit: beaten once more ... if you're confident it's true video, okay then.

dgmpgdec indicates that it is originally 25 fps...what did i do wrong?

[scharfis_brain]

what did i do wrong?

You didn't sent a sample for us to analyse :p

[Blue_MiSfit]

Nothing. It is 25fps, but if it's really interlaced, it contains 50 fields per second.

No worries :) Let's see that sample!
