I have a client that shoots mixed frame rates with their cameras. (Weddings) They want a final deliverable in 24fps (or 23.97 whatever the lowest common denominator camera is). These are big exports. Some 30 minutes long in 4K.
I am continually running into an issue where my export will stutter, freeze, desync, etc. Whatever it is renders the product undeliverable. After laboring for hours and pulling my hair out, I had a workaround that appeared to finally be working, although extremely tedious. I got through a couple of sub-20 minute exports with my workaround that were clean with a repeated process. Thought awesome, we're in the clear, but now on this most recent export the workaround failed and the same issue has arisen.
These videos are long, and even with checking playback in double-time, between the timeline rendering, exporting, and double checking, I am losing my sanity and don't know what to do anymore as the clock is burning away. The primary editor for this client has been editing these videos for several years now, so I know it is an issue on my end.
My workaround has been:
Close Project
Delete Media Cache
Create New Project
Create New Sequence in 29.97 (This is the sequence setting of the primary editor)
Copy Edits from old project into new project + Sequence
Render In to Out
Software Encode Export H.264 at 24 (or 23.97fps)
Before establishing the workaround:
I upgraded to the most current version of Premiere which definitely helped smooth out a lot, but it didn't entirely fix it.
Attempted doing a Pro Res "Master" file but that didn't change anything.
The footage being used are from multiple types of Sony Cameras (A7IV, Fx30, etc.) but the issue has been present on a Nikon camera mixed in as well.
Specs:
Macbook Pro M1 16GB of Ram -
OS: Sonoma 14.1.2
Working Storage: Sandisk Extreme Pro SSD
Ram and GPU usage have maintained headroom during exports
I've rendered 60fps down to 24 before for my own 7ish minute cinematic videos, but I've never had this issue before.
This is my first time in literally 4 years of editing as part of my income and I've never encountered an issue like this. PLEASE HELP!

I edit hundreds of hours of footage with archival material at all kinds of frame rates, and I don’t run into this issue, so I don't think mixed frame rates alone are the root cause.
Your machine technically meets Adobe's recommended requirements, but a MacBook Pro with 16 GB of RAM is definitely at the low end for 4K workflows, especially with long timelines and mixed media.
I would suggest working in smaller sequences and using Clip > Render and Replace before your final export to convert the footage on the timeline to match the sequence settings. It can help reduce strain during export and improve stability.

I only just started having these same exact issues after the update from a few days ago.
Insanely frustrating to have to export via each layer just to finish these projects.

Just curious, as Paul provided good comments ... if the client wants to end up with 24-ish FPS, why is the main editor working at 29.97?
