Creating a Multicam is taking forever

[phillip5C71]

Since upgrading to Mac OS Sequoia and Premier Pro 2025 it is taking an unusually long time to "Process Audio" when I make a multicam sequence. Before I was able to create multicam's in a matter of minutes and now it's taking hours. I'm using the same audio and video files as I always have, and I'm working on the same Mac Studio Ultra. There must be some setting or something that has changed. Any ideas??

Can you share a bit more about your files and how you’re syncing them? The details will help us figure out what might be causing the delay.

• File Details: How long are the files, and how many audio channels do they have?
• Audio Details: What’s the audio codec and sample rate?

Also, are you syncing using audio track channels or timecode? If it’s audio track channels, are you working with a specific channel or using a mixdown of all channels?

I had the same problem (with the multi-cam playback monitor view only - single cam playback window was fine without the following adjustments), until I turned my color grading layer off. I also reduced the sequence playback settings. This eliminated my issue. The color grading adjustment layer seemed to contribute significantly to the issue. I simply turn the multi-cam view off when and work with a single view in the playback monitor when working with the color grading adjustment layer on. Hope this helps someone out there!
