Mashup videos are all over the place. The quality ranges from superb to dismal. YouTube is full of sources. Since most take images from there anyway, try to pick more than just a few. How to make a good mashup video:
- Use clips from a variety of sources.
- Have a unifying theme; make it make sense.
- As always, use creative editing well timed with the music.
