I recently got back into editing on Premiere Pro for YouTube videos. I have done 5 videos over the span of two weeks and editing was a breeze, until my most recent project. I recorded days prior and just imported everything today. When doing my typical edits my systems lags horrendously and there is no playback fluidity. Previsouly I was editing 1440p footage at Full playback quality with no chops while making live edits. It was great. I have tried almost EVERYTHING to fix it. Playback resolution, Proxies, clearing cache, etc. Stuff I didn't even have to mess with before. I am having the same experience with previous projects as well... I do not know what changed. It makes 1-2 hours of editing take almsot double the time. I have to render when I make even the slightest of changes. Any advice, I am frankly discouraged and frustrated spending the better half of 6 hours trying to troubleshoot and no luck. Hardware specs below. Also attaching the unedited files I am trying to edit for my gaming channel. Not sure if this matters but the game is M for mature for any sensitive audiences.
RAM 32GB 3200Mhz
2TB & 500GB SSDs (2TB is for Adobe Application and 500GB is for Cache Files)
System is cooled sufficiently on a customer water loop.
