Hi-Fi Audio
Hi-Fi audio is recorded along with video on the video track of a VHS tape. In pre-recorded tapes, the sound will be recorded in two places: once on the linear audio track, and once as Hi-Fi audio on the video track. Hi-Fi audio quality is far superior. You need a VCR with Hi-Fi capability (such as your 8mm/VHS Dual-Deck VCR) to play and record this Hi- Fi audio; a VCR without Hi-Fi will play the linear audio track only. Your Dual-Deck VCR’s Audio Insert feature records Hi-Fi audio from a source other than your 8mm tape. Because Hi-Fi is recorded on the video track, you can only record Hi-Fi audio while you are recording the original video (see the Adding New Audio section of this Guide).
Control Track
The control track of a VHS tape contains a series of markers which the VCR uses to keep the tape playing smoothly, similar to the sprocket holes along the edge of movie film. These markers are also what the VCR uses to keep track of the hours, minutes, seconds, video frames, and VISS index marks that you see in the Tape Counter. There are 30 frames per second of videotape.
8mm Format
8mm videotape has one track. The video, audio, and control information is recorded in this one track. There are two possible recording speeds, SP (an E6/P6-60 tape will record for one hour), and LP (an E6/P6-60 tape will record for two hours). Because your 8mm/VHS Dual-Deck VCR Model GV8020 does not have record capability in the 8mm deck, the record speed will have been established when the tape was recorded, with your camcorder, for example.
Quasi Hi-8 Playback
Your GV-8050 has the ability to play back tapes recorded on
ahigh-band Hi-8 camcorder with standard (regular 8mm videotape) resolution.
