not to sound mean, but most AMV are made using actual clips from anime's insted of a low quality GIF, that way you can have a smooth motion bewteen the clips

and like everyone else said the right choice in music, and not reapeating the same sceen over again is what makes it an AMV and not just a collection of random clips, also in terms of music<to> clips try picking a theme and work from that
