You can use any video camera to record your videos, including those on that page. The problem you run into is having enough light. If you don't have enough light, the video will either be too dark, too grainy, or both. The next problem is the audio. Most cameras have a mic input, but the mixer has a line output, so you will have to use an attenuator, which is the way I do it, or you will have to use a separate audio recorder to record your mix, then sync the audio to the video. Out of those two, the audio will be a lot more important than the video. People will watch a bad video, but if the audio is bad, they won't listen.
