Précision de la timeline - Premiere Elements 11

Bonjour.

J'essaie de synchroniser 2 pistes audio afin de caler le son (pris d'un enregistreur audio 48khz) et l'image (pris d'un APN à 30Fps).

En zoomant au max et en me fiant aux formes d'ondes j'arrive à caler tant bien que mal les différentes pistes mais je n'arrive pas à synchroniser complètement les 2 pistes son - Il reste un écart audible, et en déplaçant une piste par rapport à l'autre, je me rends compte que la précision est médiocre : les blocs se déplacent à l'image près (1/30 de frame), ce qui n'est pas assez précis pour du son.

Y-a-il un moyen de déplacer les blocs audio de façon "libre" et donc plus précise (sans se caler automatiquement à la timeline des images), comme le ferait n'importe quel logiciel de montage audio ?

Merci.

I apologize for not being able to respond in your language. 

The syncing of audio tracks in Premiere Elements can be difficult.

There is an alternative method using a (free) program called Audacity.  A couple years ago a person name Chris Hull made a YouTube tutorial on how to do it.  It is in English but I think you can see how the method works just by watching.

Good luck with your project!

Thank you very much, Bill, for answering - I know a bit Audacity, use it sometimes but never tried for a video project.

I'll watch your linked video as soon as possible.

Even if it's uneasy to have full precision in syncing audio and videos, I can watch mine and hear sound coming from the mouth of the characters with a decent precision - if I don't mix both audio sources, that's ok...

What that video.  As I recall, he gets two tracks in perfect sync.  Premiere Elements, by itself, can only move the audio track a full frame at a time.  I've never used it, but in Premiere Pro, there is a precision audio sync tool.

I've just watch the youtube tip : this is exactly what I need (I didn't think of making sync operation outside Premiere)

That's ok for a simple video, with few editings, but for a huge project it would become a nightmare...

I think that if I have to make more complex video with precise audio realignment, i'll use Kdenlive under Linux os.
