Video prévisualisation fige et audio continue

[AntoineVERNIER]

Je rencontre régulièrement des "freezes" de la vidéo de prévisualisation de mon projet Première Pro

Je travaille sur des vidéos venant de la GoPro Hero 11 en 2.7k (2704x150) à 50fps

Je suis sur Première Pro 2023 (23.2.0) avec les pilotes graphiques à jour (Nvidia Studio 531.41) pour la NVIDIA GeForce RTX3060 et l'Intel Iris Xe

J'ai passé Creative cloud cleaner avant de mettre Premiere Pro et Media Encoder 2023

Au niveau de mon projet : 

• j'ai bien mis le système de rendu sur "Accélération GPU Mercury Playback Engine (CUDA)"
• j'utilie les proxy généré par ma GoPro
• j'ai activé la purge automatique du cache antérieur à 30 jours
• j'ai 29 Go de mémoire pour Première Pro (reste 3 Go pour les autres applications)
• j'ai mis la prévisualisation sur 1/2 voir 1/4, voir 1/8
• les fichiers sont sur SSD Micron 2450 NVMe de 1 To
• j'ai un espace de travail définis et le changement d'espace de travail ne change rien

Comme ça "freeze" la vidéo et le curseur dans la timeline, ...  je suis obligé d'arrêter Première Pro et de le relancer et parfois plusieurs fois sur 20 minutes

Est-ce qu'il y a une solution ?

Bonjour AntoineVERNIER,

Sorry to hear about your problems. Do you have dual monitors? If a single monitor, are you using a custom workspace? What happens with a single monitor and a preset workspace? Anything better?

Thanks,
Kevin

Hello Kevin,

Thank you for the feedback, it's true that I didn't specify, I work in dual screen, since I'm on an MSI laptop with a direct HDMI screen.

I slightly customized the workspace by removing tabs and have everything on the screen in HDMI (Premiere Pro).

I would have to test with a screen, that of the laptop

THANKS,

Anthony

I just tested:
- the screen of my laptop only (unplugged the HDMI screen), the freeze is still present
- the screen in HDMI by deactivating the screen of the laptop, the freeze is always present

If you create intraframe proxies in Premiere, either Cineform or ProRes, do they work better?

I'm wondering if the H.264 long-GOP format is perhaps the issue.

[AntoineVERNIER]

I have not tested by generating proxies by Premiere Pro
Here is the detail of my sequences:

• Type: MPEG Sequence
• Video codec type: HEVC 4:2:0

Liner media

• Type: MPEG Sequence
• Video codec type: MP4/MOV H.264 4:2:0

[R Neil Haugen]

Are the proxies you're working with also H.264?

Neil

[AntoineVERNIER]

Yes

Liner media

• Type: MPEG Sequence
• Video codec type: MP4/MOV H.264 4:2:0

[R Neil Haugen]

That's why I suggested trying to make a few proxies in Pr of Cineform or ProRes proxy formats they have available. See if the playback is smoother. As then, it would be the issue you're having is H.264 decoding.

Hi,
Sorry for my late return, I wanted to finish my current edits before testing with proxies generated by Adobe.

So, I redid a 2 hour video session and I generated proxies in QuickTime CineForm Media Resolution and I just had the problem again: no more preview during playback, no more nothing: force to close

I have another video session that I did before with proxies generated in ProRes Medium Resolution, to see if I have the problem
