What are the specs of the laptop? Video editing is resource intensive and if your laptop isn't up to snuff, it could cause issues like slow performance. If it were me, I would prefer a desktop as you generally get more performance per dollar. Laptops generally dont come with a discrete graphics card either, which depending on your software, can cause pretty significant performance issues as well. Before any real recommendations can be given, we need to know what you are working with.
proof that I'm really bad at this.
