Foreword by Rounik Sethi: Logic is a fantastic tool to use when scoring sound to video. However, there are some well-discussed limitations, and in the Logic-world that inevitably means are some less well-known workarounds too. One such limitation occurs when importing the "sync" audio from a video into Logic's Arrange area: Adjusting the start point of the video and then selecting a "bar 1" sync point that exceeds 8 bars into the video will always create the issue that Logic will limit the amount of "negative audio" to 8 bars and audio sync will be lost. Of course there have been some workarounds for this Logic quirk many of which have been explored in detail over the years. Steve H explores this very topic in his popular Logic 203: Logic's Music for Picture Toolbox tutorial. In this tutorial, Steve H joins us below to advise on the most efficient work flows that will always keep your audio and video in sync...

01 - Résoudre le négatif 8 Limitation bar

Une solution, que je montre dans mon Musique Logic pour tutoriel Toolbox Image , est de déplacer le point d'ancrage à l'extrémité de la région (ou du moins avec de 8 bars de la barre de point de synchronisation 1).

Je suggère de faire cette opération dans l'Éditeur des échantillons, car avant de vous déplacer le point d'ancrage, vous devez d'abord sélectionner la commande Éditeur d'échantillon, le «Lock Disposer position lors du déplacement de l'ancre"

Dans l'Éditeur d'Échantillons, sélectionnez:

02 - Le workflow

  1. Import audio
  2. Unlock the video's audio's SMPTE position
  3. Open the video's audio region in the Sample Editor
  4. Then choose "Lock Arrange Position When Moving Anchor". You can do this with a Key Command or by Control Clicking on the anchor's lane!
  5. Zoom out in the Sample Editor and slide the anchor point the the end of the region (or, at the very least, past the intended start point... I chose the end of the region because then I'll know that I can place bar 1 anywhere but it really just needs to be within 8 bars of the new bar one sync point!)
  6. Go back to the arrange and re-lock the audio region's SMPTE position.

Or, dans paramètre de synchronisation du projet, vous pouvez placer une barre d'une PARTOUT et votre synchronisation audio sera de retour dans la négative, sans perdre la synchronisation!

Toutes ces opérations peuvent être accomplies avec des raccourcis clavier, sauf le déplacement du point d'ancrage. Malheureusement, vous ne pouvez pas accomplir cette fonction dans le chutier audio où l'ensemble de la région de manière compacte affichée, car le darn "Verrouiller Disposer position" commande n'existe que dans l'Éditeur d'échantillon!

Choisissez Fichier

Toutefois, en zoomant dans l'éditeur de l'échantillon avant que vous faites glisser le point d'ancrage, vous pouvez toujours accomplir cette tâche afin assez court.

03 - Principales Wish List de commandement

Pour rendre cela plus efficaces, je voudrais voir l'équipe Logique de créer quelques commandes nouvelle clé:

  • Lock Arrange Position When Moving Anchor (in the Audio Bin and Arrange)
  • Move Region Anchor Point to Region End (...everywhere!)
  • Move Region Anchor Point to Playhead

... Ou tout simplement avez la possibilité d'avoir le point d'ancrage correspondent à la barre de 1 / SMPTE de position lors de la configuration de votre point de synchronisation automatique barre de 1 pour réaliser les étapes 1-6 en haut!

J'espère que cela aide! Voilà le genre de choses qui sont tellement plus facile de montrer dans les vidéos!

    Great Tip!!! However - I'm having a problem. I'm creating a master project from which I'll create my individual cue projects. What I want to do is import my audio from my movie and move the anchor to the end of that region in my master so I only have to do it once. My reasoning is, I can Save As to a subsequent cue and then change my start point. The problem I'm having is, when I move the anchor too far, maybe 8 minutes into a 15 minute short, the audio stops playing back. When I back it up, it works again. And recommendations to solve this? Thanks. But aside from this bug, it's a great time saving tip.

    I don't know why you're running into that issue. Why work with such a big chunk of video? If you've got vis code you can cut the video into scenes using your locators and your "Export Audio to Movie" command to create smaller... usable chunks.
