Don't be discouraged, you can use a digital camera which, in most cases, can record good quality videos. Or use your smartphone. In many occasions a tripod can be useful and pay attention to the light: especially if you are shooting indoors, make sure there is sufficient light, reordered videos always seem darker than we see them with the naked eye. Sound: you need an external microphone (e.g., A "lavalier"), because the quality of the sound picked up by the cameras is strongly affected by background noise.

Regarding the so-called "video editing" you need a good software; there are several free, e.g., Windows Live Movie Maker or iMovie for Mac. Professional software such as Final Cut Pro or Premiere from Adobe are subject to charges. Audio must be added to the video, otherwise the video won't be understood. A good idea is to show your video to people of different ages to hear their impressions and make some corrections.
