Issue with Playback Performance in Premiere Pro Version 24 and Later
Since version 24, there is a significant playback performance issue when the timeline scroll setting in Preferences - Playback is set to “Smooth Scroll.” This issue did not occur in version 23, but it seems to have resurfaced.
Steps to Reproduce: The more clips you place on the timeline, the slower the playback becomes. Once the number of clips exceeds a certain threshold, the playback button becomes unresponsive, and you may need to terminate the Premiere process to close the application.
This issue does not occur when the timeline scroll setting is set to “Page Scroll.”
Additional Note: After upgrading to version 24.5, I encountered another issue where Premiere files created in version 23 could not be opened after downgrading back to version 23. Therefore, I am reluctantly using version 24.5.
