audio out of sync for 23.976fps dvd's

[addictarmy]

Trying to rip some anime (evangelion) and I am having an issue with the audio. At the beginning it seems ok but by the end of the video (an hour or so) the audio is out of sync by a couple of seconds.

This doesn't happen on all the discs either.

Vol 1 which has a frame rate of 29.97 came out great, but Vol 2 which has a frame rate of 23.976 ended up witt the audio out of sync.

Anyone if I have to do anything special using Gordian Knot (or any of the tools it uses) to get the audio to sync up for a frame rate of 23.976?

Since the frame rates are different I'm assuming that is what the culprit is. All the other DVD's I've ripped have always been 29.97 and ended up ok.

Thanks.

Welcome to the forums, addictarmy.

As this appears to be a Gordian Knot related issue, and not specifically related to audio encoding, I'll move it to the Gordian Knot forum now, hopefully someone there can give you some help. However, it will help us to help you if you post your GKnot logfile, there is not much analysis that can be done from your current report.

Additionally, I'd recommend you take a look at this tutorial (http://www.doom9.org/ivtc-tut.htm) to help you get a better understanding of these framerate issues and how video is stored on DVDs. Hope this helps,

[addictarmy]

Thanks,

Read the tutorial and tried again and still have the same error.
I believe I followed the guides properly.

Also by following these instructions:
http://www.doom9.org/index.html?/gknot-main.htm
"Frame Rate = 23.976 fps: This is the result of activating Forced FILM for an NTSC movie. If the Video Type is FILM or FILM at a percentage higher or equal to 95% you're all set. If the percentage is lower or the type is NTSC then you have to set Field Operation to None and perform IVTC (that process will be explained later on)."

I had a Frame Rate = 23.976 and a NTSC of 75% so I set field operation to none, and when I choosed save and encode from GKnot I checked Inverse Telecining.

Here's the log file:
