30 mins-2 hrs - Camcorders record their signal at about 400 lines of resolution, slightly less than Mini DV, but substantially higher than 8mm or regular VHS formats. Most often, HI-8 camcorders record sound in hi-fi stereo. Slight quality loss is suffered when copying or editing from HI-8, but a better than average image is maintained. Tapes from HI-8 camcorders generally must be played using the camera as the source, which means the user often must connect cables to their television or VCR. HI-8 tapes can be bought in 30, 60, and 120-minute lengths.

45-90 mins - A format that is far superior to HI-8 or 8MM. Sony was the first to introduce this format and has done a great job. It is backward compatible, meaning that the new Digital8 camcorders and VCR's will also play your 8MM and HI-8 tapes. You do not have to buy special tapes to record in Digital8. A regular 8MM or HI-8 tape will record up to 60 minutes of digital video and audio. Because of the design, using regular tapes is not a problem, but it uses twice as much tape. A 2 hour HI-8 or 8MM tape will record 60 minutes when done in the Digital mode and records up to 500 lines of resolution.

30-80 mins - The smallest of the video formats. They take and maintain crystal clear images because of the nature of a digital format. Editing enthusiasts benefit from Mini DV as well, since copying between two units is done with no quality loss. That means edited or copied video looks and sounds every bit as good as the original footage. Mini DV tapes are available in 30, 60,63 and 80 minute lengths. Digital camcorders have the highest resolution of all the camcorders, starting at 500 lines.
