Dude, you need a pretty decent computer to edit GoPro stuff. Like, at least 8 gigs of RAM is a good starting point, and a relatively new CPU. If you're messing around with 360 video, you'll need a much more beastly machine. It's all about that processing power.

The system requirements for GoPro editing software vary depending on the specific software used. However, we can generalize based on the most popular choices, like GoPro Quik and GoPro Fusion Studio. Generally, you'll need a reasonably modern computer to smoothly edit GoPro footage. For example, for optimal performance, Quik suggests a 64-bit operating system (Windows 10 or macOS 10.13 or later), a minimum of 4GB RAM (though 8GB is recommended), and a reasonably modern processor (Intel Core i5 or AMD equivalent). Hard drive space needs depend heavily on footage length and resolution, but you should have at least several gigabytes free. It is also helpful to have a dedicated graphics card (GPU), although not always strictly required for basic editing. GoPro Fusion Studio, used for editing 360° footage from the Fusion camera, tends to have much higher system requirements due to the processing-intensive nature of 360° video. You'll generally want a much more powerful computer with significantly more RAM (16GB or more is recommended) and a more powerful processor and GPU. This is because stitching 360° footage requires considerably more computing power.

For simple editing of short clips with lower resolution, older hardware might suffice; but for smoother editing of high-resolution footage, extended clips, and complex edits, a higher-end system is strongly suggested. Always check the specific system requirements on the GoPro website or software installer before downloading and installing any GoPro editing software for the most up-to-date and accurate requirements.
