Premiere Pro 25.4.1: Heavily Pixelated Footage (Moiré Effect) on Timeline - Desktop Specs Provided

Hello everyone,

I've just started using Premiere Pro 25.4.1 and am encountering a rather perplexing issue. After importing several HD video clips, when I drag them onto the timeline, the footage appears heavily pixelated, almost like a moiré effect. The source footage is HD (1920x1080) at 30 frames per second, and my project sequence settings match this exactly.

Here are my desktop specifications:

• Operating System: Windows 11
• Processor: Intel Core i9-14900 @ 2 GHz
• RAM: 64 GB
• Graphics Card: 128 MB (dedicated)
• Storage: 954 GB (available)

Given the generous amount of RAM and the high-end processor, I'm quite baffled by this visual degradation.

Has anyone else experienced a similar problem with footage appearing pixelated on the timeline, particularly resembling a moiré effect? What could possibly be the cause, or are there any settings I should be looking at within Premiere Pro or my system that might alleviate this?

Any insights or suggestions would be greatly appreciated.

Many thanks
