Canon's Optura 10 camcorder adheres to an international MiniDV standard. Using MiniDV cassettes, audio and video are recorded digitally. The MiniDV format delivers more than 500 lines of horizontal resolution. In terms of picture quality, this is about 25% better than the best analog formats. It features a DV terminal, also known as a FireWire terminal, which conforms to the IEEE 1394 standard. Using this terminal, you can transfer digital video and audio to and from a computer equipped with a DV terminal, another DV camcorder, or a DV VCR. The digital data transfer occurs without any degradation to the image or audio. This means you can edit movies on your computer and maintain the same high level of picture and audio quality when you transfer the edited movie back to DV tape using the DV terminal. And with supplied Canon DV Messenger software, the camcorder can be used for Internet Video Chat with family and friends across the country or around the world!
