Highlander Rip

[yoshi98bc]

No matter what I do I can't get the video to synch with the audio. What are some causes for this and what can I do to try and fix them?

[TheWEF]

mp3? bitrate? ..? - c'mon!

[yoshi98bc]

Sorry, was in a rush. I am encoding it with Ac3. Just can't get the video to line up with the audio.

[TheWEF]

ok, you get one last chance, i will not ask again.
describe the whole procedure you went through and the programs you used: ripping, demuxing, frameserving,encoding,interleaving,...
IN DETAIL!
if you don't give enough information there is nothing i can say about your problem. it could be anything...

I have encoded about 40 movies using the guide for divx 4 for gordian knot. I ripped the dvd with smartripper version 2.40, then made my dvd2avi file with gordian knot. I selected forced film and set demux all tracks as it says in the guide. However, I noticed that this was an NTSC file above 95% percent so I tried not enabling forced film, set the frame rate to 23.976 in the gordian knot interface in the lower left corner, and selected under field operations when encoding it to the telecine setting. No matter which way I tried, with forced film or telecine, the audio was off in both tries. I was muxing the ac3 audio also. What else can I tell you. I haven't had a problem before so I don't know the more experienced techniques. Tell me what else I need to tell you and how to provide it and I will do just that. Thanks

[TheWEF]

how about the other 40 divx4-movies you encoded? they have ac3-sound as well and play fine? or do you normally transcode to mp3?

in what way is the audio not in synch? always the same delay or progressive,...?

did you try to mux audio manually with nandub? did you try different interleaving values?

anything you changed in your system? installed some sw?

Another thought. If this particular "Highlander" was not the film, but was "made for TV," then you should leave it at 29.97 and not attempt to convert it to 23.976, as it was recorded in video, not film. Video-camera recorded sources should not be inverse Telecined, since they are not Telecined. Just an additional thought, since this might be causing your sync error.

@jggimi i think that you are right


When dvd2avi say only ntsc at xx% the movie shouldn't be telecined
in this case i recommend to aply a nandub filter : Deinterlace -Area Based v1.2 by Gunnar Thalin

Could be this or not :rolleyes:

I would Rip the VOBs agian and go into settings in smartripper and select key-check Every Cell Id. This has wrked for me with Warner Brother films. Maybe you have the same problem. Not sure if this will help but it's worth a try.

Of the other ovies that I have encoded, about 10 are in dolby digital, the rest in mp3.

The audio comes before the actions in the movie. It appears to be consistent throughout.

I tired to mux the audio manually with nandub. Same problem.

Didn't install any new software and the system is the same.

When you say change the interleaving values. When I muxed manually I was changing it to 96ms. What else should I try? Would this make a difference?

I appreciate the help. First problem in about 40 tries are pretty good stats. I guess it's time to learn the more advanced stuff. Thanks again.

it should be possible to adjust this manually when muxing with nandub.
play with the "delay" value in interleaving and give it a few tries.

e.g. if the audio is about half a second early try delay 500ms.

Hi,

When muxing audio in Nandub manually, it seems that a delay (calls it "pre-loading" of 500ms is the default.

However, I have had trouble with audio sync problems with this.

My solution: set "pre-loading of audio" to 0, and enter the value given when demuxed in dvd2avi in the "audio delay" box. (You can get same value from Gknot if you load the audio file into the audio encoding tab).

This solved any sync problems I have had.

[TheWEF]

ok, it's not called delay, it's called audio skew correction.
dragoman, this has nothing to do with preload, that's just the buffer.

[dragoman]

Ooops! My mistake....

[yoshi98bc]

Thank you very much for all your help. I ste the delay to 1000ms in nandub and it looks pretty synced to me. Thank's for your pateince WEF.

Any ideas why this might have happened? Just curious.
