I faced the same issue after filming coastal landscapes with a drone. While searching for a quick fix, I discovered  https://www.pdfchef.com/remove-audio-from-video/ . It's designed for simple video editing tasks, especially removing unwanted audio tracks. I uploaded the footage, muted the sound, and exported the edited version in just a few clicks. Everything worked directly in the browser, and the process was incredibly easy. The final video looked fantastic, and my experience was very positive from start to finish.
