A Few Quick Problems for you to solve

[humet]

Hi,

I've been converting NTSC AVIs to PAL DVDs and have been bumping into these problems:

1) BeSweet keeps changing the length of my Audio files when I try to do a WAV > AC3 encode even though I am not changing the frame rate and it has no errors in the log file.

2) I use AC3Machine to do the WAV > AC3 and I get the audio and video the same, I finally encode to the VOBs the audio is in sync at the start but not at the end.

3) What is the best way to convert from NTSC AVI to PAL DVD as the method i am doing isn't really working well and i always have problems with sync issues. The method I am using now is this -

a) Extract WAV with "AVI2WAV"
b) Load WAV into BeSweet and change Framerate while converting into an AC3 file
c) Create an AVS file with this script:

avisource("anavifile.avi")
bicubicresize(720,576)
AssumeFPS(25)
ConvertToYuY2

d) Use CCE Guesser to find correct Average bitrate to use in CCE.
e) Encode to MPEG2 File
f) Use either Maestro or Adobe Encore DVD to compile the DVD

But normally when using this method I get lots of out of sync DVDs.

Thanks for any help.

Please do not assume I am using copyrighted material as another one of my threads got closed down because of that misunderstanding.

1. Post your logfile, and how do you know the length has changed?

2. No idea.

3. Answer: there isn't a good way. Why isn't there a good way? Because there isn't a legal demand for doing this, despite what you say not that many people are doing NTSC avi > pal DVD for legitimate reasons.

Suggestions:

I'd guess your sync problems have to do with your avisynth script. That assumefps(25) is probably what's giving you sync issues. I'm sorry but I can't imagine a legitimate reason for converting NTSC avi to PAL dvd.

Your post also mentioned not changing the framerate for audio at first and then later you said you were. Are you using FRC or not? Once again a logfile would be helpful.

Don't use avi2wav, demux with VdubMod.

This is just a straight WAV > AC3 with no Framerate change just for testing reasons, and the lengths still change at the end. I know that because I load both the files into WMP and look at the lengths.

Reason for needing to do this is because I got a few clips from a website for a college assignment, and I need to put them into my DVD (I'm doing an interactive DVD on Extreme Sports).

Is BeSweet any good for changing the Framerate as after changing the framerates I always thought the video was the correct length and the audio was faulty, could it be the other way around?

Cheers,
