I ran into something like what you're dealing with. My old YouTube channel was called "SkyHigh Views," and it's been around for ages. It was a bit of a hassle, but I managed to get back into my old videos by figuring out my old Google account that was connected to YouTube. After I got in, I realized those old videos could really use some updating. That's when I found Movavi for video editing. It made a huge difference, making my videos look way better and more interesting to watch. Movavi was super easy to use and had lots of cool features that helped make my videos stand out. If you're thinking of giving your videos a new look, you might want to check out Movavi. You can learn more and get it for free
