Audio out of sync

[michcio]

Hello!

It was a really long time ago I authored a DVD and I felt like trying it out again.
I'm using GfD and therefore I need to encode .avi to .m2v and get an .ac3 audio from the same avi.

The problem is that when I make my dvd-project with the m2v and .ac3 file they get out of sync.

My avi is in NTSC format and I am converting it to PAL but this shouldn't make any difference if I remember correct? (i.e. NTSC->PAL conversion will still work with same audio?)

Here's my avisynth code while encoding to .m2v:

AVISource("myMovie.avi")
Spline36Resize(720,576)
AssumeFPS("pal_film",true)

and I use HCEnc for the m2v encoding and ffmpeg to get out my .ac3 (bitrate: 192 sampling rate: 48000)

am I missing something here or what's the explanation of this out of sync problem?

Regards
michcio

No, it wont work with same audio. You must adjust/stretch it.

But I wouldn't convert it to PAL. Most european tvs and dvd players supports NTSC just fine.


edit: Or the assumefps with true should speed up the audio with 4%....if you are using the avs script in ffmpeg then.

Ah ok. Well the thing is that I want to create a project with several AVIs some are in PAL and some in NTSC so I have to either convert PAL->NTSC or NTSC->PAL.

How can I correct strech an audio from NTSC->PAL or PAL->NTSC?


EDIT: I don't think I can open up avs script in ffmpeg :/

I'm sorry that you are so poor and destitute that the idea of just putting PAL on one DVD and NTSC on another DVD is going to kill you financially. Yes, converting between PAL and NTSC makes SO much more sense than spending 25 cents on another DVD - not.

Here's one guide:

You can search for NTSC <-> PAL conversions in our Guides section. There are many others as well.

Any decent build of ffmpeg for Windows supports Avisynth scripts fine,

please stop posting false information.
