Bonjour à tous,
Je suis sur Vegas Pro 365, je souhaite importer une animation créé dans After Effect avec la couche alpha afin d'avoir la transparence. Pour le moment je crée une suite d'image PNG dans AE puis j'importe un media "images fixes" en créant une séquence. Ma question, est'il possible de créer un unique fichier vidéo dans AE puis de l'importer dans Vegas Pro pour avoir la transparence?
Merci pour vos éclairages.

s it possible to create a single video file in AE and then import it into Vegas Pro to have transparency?
My experience over the years with Vegas Pro is to be able to use a video event with an alpha channel that includes 0% opacity, that video event needs to be in the .avi format and uncompressed (usually meaning a huge size). If rendering in Vegas Pro to achieve this, the render settings would be:
Not having used AE, I do not know if this can or can't be done in AE
Merci pour votre réponse, je n'arrive pas à avoir la couche alpha quand j'importe une animation, même en modifiant les propriétés de la séquence.
I can't get the alpha channel when I import an animation, even changing the properties of the sequence.
When adding an alpha video event to the timeline in Vegas Pro, the Properties/Media tab needs an alpha channel format set (Straight or one of the Premultiplied option), as per:
I'm not sure if that is what you were referring to in mentioning properties.
A .png image sequence should work but each .png image would need to have its properties set (if they are not already set by default), though that can be done in one hit if you have Vegasaur.
If it is an .avi video that you are using and changing the alpha setting in Properties/Media, then it may be that the .avi is not uncompressed and/or with its alpha channel activated when it was rendered.
Looking at Adobe's help website and AE's user manual, it does seem that AE can export .avi (Video for Windows). But unfortunately there was no detail about format settings including whether or not uncompressed and alpha enabled settings were available,
