Currently, I use my MacBook if I build a quick video was filmed, with a webcam.
The MacBook, it is simple, the webcam is in. The computer is also equipped with video editing software called iMovie base.

If I video material, if I’m on the street, I have my Casio Exilim Zoom EX-Z850. I love this camera – Specifications: 8.1 megapixels, 3x optical zoom, 8 x digital zoom, and really small, but with a display of 2.5 inches. In short, it can pack a lot into a small package.
Besides the camera, I suggest you have a tripod. Just a little to the table is good – you can usually take for $ 20 or less.
And take a little more memory cards. Here are videos and photos with the camera. I suggest you cards with 2 GB of memory. They fit so or video footage of an hour and lots of photos.
You can also use a camcorder to create videos. If you use this method, you must have a FireWire cable, you can connect the camcorder to your computer.
In which direction you go, you can delight of videos online.
If you have no camera, but to a shopping-comparison to the best deals.
