Premiere Pro Beta – Extreme Lag After Every Cut?

Hey everyone,

I’m currently using Premiere Pro Beta 25.2.0 and running into a super frustrating issue: Whenever I work with a large timeline ("RAW"timline – I drop all the footage from the day in and start cutting with Q and W), Premiere lags for 1–5 seconds after every cut. (I use proxys, playback resolution 1/4)

Switching to the regular Premiere version completely fixes the issue. In the Progress Dashboard, it always says "Auto Color complete", and I suspect that’s the culprit. Since my timeline starts out over 2 hours long, Auto Color is applied to everything—even though I eventually cut it down to just 1 minute.

I had the exact same issue before when using "Enhance Speech".

Does anyone know how to disable Auto Color? Or any workarounds to make things run smoother?

Appreciate any help! 🙏
