NTSC DVD TO PAL DVD
 
Hi,
I got a ntsc dvd,progressive,hollywood movie, that I want to convert
to pal dvd.

When I preview in DGIndex,with Forced FILM off,the information says :
-Frame rate: 29.97
-Video Type: NTSC
-Frame Type: Progressive
-Frame struct: Frame

With Forced FILM on the frame rate changes to 23.976.

So the question is,what settting should I use,Forced FILM on or off?

There is no interlaced parts at all in this movie.

Thanks

Real progressive 29.970 materials are pure theory except perhaps if this is a computer generated movie, 100% digitally mastered. But even this, I have doubts there are some on the market.

Your movie is pulled-down, as usual. So use Force film.

Okay thanks.
So then my script will be something like this:
Quote:


LoadPlugin("C:\Programfiles\MovieStacker\Filters\D GDecode.dll")
LoadPlugin("C:\Programfiles\MovieStacker\Filters\R emoveGrain.dll")
LoadPlugin("C:\Programfiles\MovieStacker\Filters\V SFilter.dll")
Mpeg2Source("D:\DVD\VIDEO_TS\ntscdvd.d2v")
LanczosResize(704,336,2,50,716,380)
RemoveGrain(Mode=2)
AddBorders(8,120,8,120)
VobSub("D:\DVD\VIDEO_TS\ntscdvd.idx")
AssumeFPS(25.000, true)
Two more questions,I guess the subtitles will be displayed correct
even if we change from 29.97-23.976 to 25?
Or is the timecode for 29.97 and have to be manually changed?
And finally the audio will be 29.97 to 25 conversion ?

As far as I understand the pulldown issue,its a 23.976 stream that
is flagged/forced to playback at 29.97 framerate.(if thats correct
im on the right track I guess 8O )

I suggest the usage of some postprocessing in mpeg2source (add "cpu=4" as parameter).

Good question. I think that with "assumefps" there is no problem. But... that is a good question.

Yes it is, but... read below

You are right.
And that is why you should give DGPulldown a try : encode with no wonder about the fps (so you will produce something in 23.976 but with PAL resolution) and DGPulldown will flag it to be read at 25 fps !

I never tried but that is the goal of the tool. And it seems to work.

No problem with the subtitles; no problem with the audio :!:

Which program do you use for authoring? You really should use non-permanent subs as that's what DVD is for. DVD2SVCD might be helpful in this case as it should handle subs as well with NTSC->PAL conversions.

Pulldown from 23.976fps to 25fps produces a slight jitter which I found annoying (probably because I knew it was there :wink: )

The audio conversion is 23.976fps->25fps instead of 29.97->25.

Ill give DGPulldown a try,it seems to be a good solution.

btw,I encoded a short clip with AssumeFPS(25.000,true),
and as far as I can see the subtitles displays correct.

@Boulder,lately ive used DVDAuthorGUI for authoring,yep mostly
I use non permanent subs,wich DVDAuthorGUI supports fine.
The Script here was more or less for testing purposes.(or KVCD),as
im new to the NTSC to PAL stuff.


Ok Ill use 23.976fps->25fps when doing audio.
