NTSC DVD(720x480) to PAL DVD (720x576) resize or borders?

[pankov]

I'm trying to convert a few NTSC .vobs to PAL. I know I'll have some frame rate problems but if suppose I find a solution to this what should I do with the aspect ratio?
The NTSC trailers are both in 4:3 and 16:9 anamorphic. To convert them to PAL should I only add black bars to fill the whole 576 height or should I use resize to 720x576?
Can someone give me a good explaination and if possible a avisynth script?

You MUST use resize from 720x480 to 720x576.
You must re-fps from 23.976 fps (NTSC movie) to 25 fps (PAL) too.

Movie get about cca 5% quicker (sorry), but this needed for playing in PAL systems.

I created a FILM2PAL conversion function a while ago. you can find it in an attachment called bob.zip in this thread (http://forum.doom9.org/showthread.php?s=&threadid=31924)
sample usage:Import(bob.avs) #I assume the most common filters to be present in GKnot lib
#You still might have to remove a few of the first lines
#if you don't have all filters installed.
#Greedy and decomb are required however.
video=mpeg2source(dvd.d2v) #Setmemory line is only useful if you have
BicubicResize(720,576,0,0.5)#a relly new version of AVIsynth.
FILM2PAL(video,0) #Speeds up the video to PAL speed
#remember to adjust audio manually.

I've downloaded the bob.zip and used tried to use it but I got an error complaing about the parameters of GreedyBob function
!?!?
I looked at your script and found that in NTSC2PAL there is only one param in the call of GreedyBob. I have no idea but the default value doesn't work
!?!?
I tried it three different version of avisynth (2.05, 2.04 and 1.06) but the same error
:(
Can someone explain me how the default values for params work?

I fixed the script and used it. I wasn't satisfied with the results
:(
I got a good video - no speed problems (no jumps or so) but the image quality wasn't as good as I expected. I suppose the resize function made it this way. I tried VirtualDub's bicubic resize and gave better results. Can reproduce these results in avisynth scripts?

Another question:
Which programme and settings should I use to reencode the avisynth stream to MPEG-2 so I can import it in DVDMaestro?
I have TMPGEnc but don't know what settings should I use
Can someone help me? Has any one done this before?

I'm sorry about the mistake with only one parameter to the GreedyBob call. Somewhere the deafult function stopped working as intended, probably on the change from 1.05 to 1.06, because I know it worked a while ago. I thought I had changed all calls, but as I don't use these functions very often, I must have missed this occasion. I mostly do DivX and then framerateconversions are not necessary. I'll post a bug-report on the sourceforge project page. (http://sourceforge.net/projects/avisynth2)

@dividee

Thank you for the explanation (https://sourceforge.net/tracker/?func=detail&atid=482673&aid=600071&group_id=57023).

@everybody else

arguments are only optional if they are surrounded by quotes. A greedybob function should look like this:function GreedyBob(clip clip, int "topfirst")
{
loadplugin(greedyhma.dll)
t=default(topfirst,1)
a=clip.greedyHMA(t,0,0,0,0,0,0,0)
b=clip.greedyHMA(1-t,0,0,0,0,0,0,0)
c=interleave(a,b)
return c
}
and it could be called in any of the three fashions:video=AVIsource(foo.avi)
Greedybob(video)
Greedybob(video,0)
Greedybob(video,topfirst=0)

@hakko
Thanks for clearing this up.
I have a question about the NTSC2PAL convertion
I used your function but in still pictures with horizontal lines in the picture (like the Dolby Digital Logo in trailers (dd-egypt.vob) it kind of moves up and down.
:(
I tried using only BicubicResize and found that it's not what's causing the problem.
I suppose the problem comes from GreedyBob or Weave but I'm not sure what I can do to fix it

Please, someone, help me!
