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
a high-band Hi-8 camcorder with standard (regular 8mm
videotape) resolution.
