Audio fps, how to know?

[NormaJ]

Is there a way to know, from an elementary audio stream, wich FPS it is?
TIA

Well you could try gspot or avicodec might work. Or possibly virtualdub. Worth a try. Are you working with ac3 or mp2 files?

Does audio even HAVE FPS, since audio doesn't have any F to start with?

48Khz sample rate for DV, DVD, etc.

[Baldrick]

no, no frames per second...

[NormaJ]

OK, no frames per second, but must be some difference between an audio that is into an avi 23.976 and an audio that's into an avi 25.000. If not, there would not be synch issues. When you convert a video to 25 fps, you must also convert the audio that comes with it.
So how is this item called for audio, if not fps? And how to know what kind of audio you are handling, related to this?
Sorry that I can not explain better.
Thanks.

The difference is length, but unless you kow the running time of the video, you won't know if your audio is going to sync. Audio does not have a format like NTSC or PAL, it simply has a running time.

[NormaJ]

Thanks.
So, it's all about how fast the audio is running, or, the same thing, how long it lasts.
Right?

[guns1inger]

What are you trying to do that is prompting these questions ?

[NormaJ]

Hum. I've got the English DVD version of The Ryan's daughter, and I wanted to add a Spanish audio that I got from a VHS rip. The original material is 23.976, and the Spanish mp3 audio doesn't match at all, it's an horrible mess, though it lasts the same as movie does.

[guns1inger]

I am assuming English as a language, not English as in PAL Region 2.

Is the VHS version NTSC as well ?

The difference between PAL and NTSC is approx. 4%. That is, the PAL version would have a running time approx 4% shorter (or faster, if you prefer) to the NTSC version.

[NormaJ]

Yes, the PAL region 2 will be released next month. And about the old VHS tape, I'm assuming it's PAL, because I live in a PAL country. That's why I was asking for a tool that could tell me this for sure. It would be a huge work to rip the video from the VHS just to see what fps it is.
Well, I have tried both, checking the pulldown box in Tmpgenc, and changing framerate to NTSC film video, still Spanish audio doesn't match.
Right now I'm processing again with Tmpgenc, just the way the guide of DGPulldown indicates, then will run this app and see what happens.
Anyways, I'm starting to think that it's going to be a hard job. I guess both DVD and VHS releases are just different. Messing up with my m2v and my Spanish mp3 into Media Player Classic, I've realized that the time of the Intermission is quite different (about 9.5 sec. longer for the audio), should both be PAL or not.
Best regards.

I wouldn't screw around with the video side of it, just try to match the audio. If you have sections that are different, such as the intermission, then you will have to edit the audio file to match. If you have the original case for the VHS, it will probably tell you the format. I know most VHS tapes released here clearly say PAL somewhere on the case.
