Art Beat is giving away a free clip every day.
Visit the link and register to get your clips because you never have enough cloud/wave/nature/etc clips. The quality is incredible and with some color correction, you can give these clips a totally different style. Best of all: they are all free!
Actually, just browsing the library is a nice source of inspiration (just wasted 12 minutes doing so)! I love the church series for example.
