NTSC to PAL - Keep 5.1 audio ?

[asd343]

Hi

Is there any way at all, to convert a single .vob movie file from NTSC to PAL, and still keep the 6 channel (surround) sound?

What about using DVD2SVCD (in DVD output mode)?

You should be able to save and speedup the 6 channels in wav format using besweet and then re-encode using a decent AC3 encoder like softencode.

If you mean keep the original track without re-encoding, I imagine you can pad the video stream rather than take the traditional speed up route, not sure what the best way to do this is though (maybe avisynth forum is a good place to find out).

If you don't want do reencode the audio, just use this script for converting your Video:

loadplugin("decomb5.dll")
xxxsource("NTSC-video.xxx")
telecide(post=0,order=1).decimate(cycle=5) #remove this line, if movie is already progressive

changefps(50)
separatefields.selectevery(4,0,3)
lanczosresize(720,288).weave

the downside of this method will be, that
- you have to encode interlaced, which needs more bitrate.
- there will be two slight stutters per second (not noticeable to a normal TV-consumer)

Are these stutters the same as you get when playing back NTSC on a PAL TV (through a standalone)? If so, then I'd say it's very noticeable (just look at a panning scene).

No, these Stutters are the same you have while watching US-TV-Shows in PAL-Land.
Scharfis Script does the same Videoconverters do - a interlaced Norm-Conversion.

@Kika: don't confuse convertfps with changefps
my script just repeats twice a second one field!
you may compare it with telecined FILM on NTSC

This conversion can be compeletely undone with
telecide(post=false).decimate(25)

even with convertfps my script will look much smoother than a NTSC->PAL conversion, because there is no Telecine between 24fps and 25fps.

@The belgian: I think those stutters are only noticable if you're really searching for them.

NTSC60 @ PAL50 output of DVD-SAP's is crap.

@scharfis_brain

Oops, you'r right. I mixed up two different Convertion-Methodes.

[The Belgain]

Ok, thanks for the clearup. I am doing NTSC --> PAL conversions to avoid the horrible stuttering from my DVD player converting to PAL50.

I'll give this one a go.
