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.
