Convertir vidéo 25 fps en 50 fps

Bonjour à tous,

 

Je travaille actuellement (pour un projet perso) sur une vidéo au format 25 fps et j'aimerais savoir quel est le meilleur moyen via Premier Pro de la transformer en une vidéo de 50 fps.

 

Le fichier d'origine est un 1080i 25 im/s avec trames entrelacées. (ligne du haut d'abord, balayage MBAFF)

 

Dois-je effectuer la transformation via Media Encoder ou est-ce plus simple sur Premier Pro directement ?

 

Dans l'idéal j'aimerais un fichier final de 1080p50 et désentrelacé car il s'agit d'une vidéo avec des images rapides et beaucoup de mouvement, donc j'ai besoin d'un rendu le plus fluide possible tout en conservant bien sûr le maximum de la qualité d'origine du fichier.

 

Existe-t-il différentes façon de procéder ?

 

Merci d'avance de vos précieux conseils.

 

Bonne journée à tous.

 

Andy

    Place the 1080i footage on a 1080p50 timeline and export it as 1080p50. That´s all you have to do.

     

    You can also edit the 1080i footage in a 1080p50 timeline without exporting the footage to a new file and then use that file in the project. That can be good to know.

     

    If you do that you will retain the fluid motion from the 1080i file. If you deinterlace it you will get bad quality with choppy motion. Deinterlacing is and has never been a way to make footage motion fluid and smooth.

    Bonjour Averdahl,

     

    Merci pour le conseil. Je vais essayer ça. 

    Ok, bon à savoir (pour le désentrelacement).

     

    Pour le projet, comment dois-je procéder pour le paramétrer en 1080p50 dès le départ ?

     

    Puis-je le faire au moment de lancer un nouveau projet ?

     

    Merci encore.

     

    Andy

    When you create a new Sequence via File > New > Sequence you can go to the Settings tab and change the Timebase from xx to 50,00 frames/second. Click OK when done.

     

    If you want to change an existing Sequence, select the sequence and go to Sequence > Sequence Settings and change the Timebase from xx to 50,00 frames/second.

     

    You cannot set the project itself to a specific framrate, it´s always the Sequences that you set to a specific framerate.

    For the project, how do I set it to 1080p50 from the start?

     

    Can I do this when starting a new project?
