Probleme avec la prévisualisation et l'exportation

[defaultfi59f5dicpfh]

Bonjour, j''ai un problème sur after effect, quand j'utilise l'effet "spectre audio" la prévisualisation et très longue et l''exportation presque 1h!
J'ai bien mis l'exportation en h264, mis le max de RAM disponible ( 13 ) Et je pense avoir un bon pc ( 3060 et ryzen 5 5600x ). Merci de votre aide

Nothing wrong. It's just how AE works. You may want to read the online help and reasearch the millions of "How do I optimize performance" threads here and elsewhere on a) how some things in AE work and b) how to potentially optimize and circumvent some of those bottlenecks. Again, rendering times of one hour e.g. for a 4 minute clip can be perfectly normal depending on what effects and features are being used. Audio Spectrum is not an accelewrated effect, anyway. After all, that would still be only a few seconds of actual processing per frame.
