Comment accélérer la cadence de vos films en utilisant la fonctionnalité Modification de vitesse avec @guillaume.leoni.
Vous voulez augmenter l’intensité dramatique de vos vidéos en jouant avec la vitesse ? Guillaume (alias @guillaume.leoni), créateur de contenu Instagram, vous montre comment tirer le meilleur parti de la fonctionnalité Modification de vitesse dans Adobe Premiere Pro.
Ouvrez Premiere Pro et importez votre métrage. Faites-le glisser sur le panneau Montage. Parcourez votre métrage et utilisez l’outil Cutter pour le couper au niveau de la section qui vous intéresse. Positionnez ensuite la tête de lecture à la fin de votre séquence et appuyez sur la touche O pour définir votre point de sortie.
Conseil : bien que vous puissiez facilement changer la vitesse à l’aide de l’outil Vitesse, Guillaume recommande d’utiliser la fonctionnalité Modification de vitesse pour obtenir un meilleur résultat.
2 Réglage de la vitesse du métrage
Cliquez sur votre métrage dans le panneau Montage
, cliquez avec le bouton droit et choisissez Afficher les images clés des éléments > Modification de vitesse > Vitesse. Accédez ensuite au panneau Options d’effet et, sous Modification de vitesse, appuyez sur l’icône de chronomètre à côté de Vitesse. Déplacez la tête de lecture le long de votre métrage jusqu’au point à partir duquel vous voulez régler la vitesse et appuyez sur l’icône d’ajout/suppression d’image clé. Un marqueur gris apparaît. Faites-le glisser jusqu’au point où vous voulez que se termine la transition de la vitesse. Vous remarquerez qu’il y a à présent deux pointeurs. Vous pouvez continuer à les déplacer pour les positionner correctement dans le temps.
Revenez dans le panneau Montage et faites glisser votre calque vidéo vers le haut, ce qui facilitera le réglage de la ligne d’effets de décélération. Survolez cette ligne et faites-la glisser vers le haut pour accélérer la lecture à partir de l’instant choisi.
3 Lissage
Jouez avec les réglages jusqu’à obtenir les changements de vitesse désirés. Le but est de créer une accélération graduelle. Ajustez la ligne/courbe à votre convenance. Dès que vous êtes satisfait, effectuez le rendu de votre film en choisissant Séquence > Rendu de l’entrée à la sortie et visionnez le résultat.
