Overview:
To counter the introduction of the Super-VHS format, Sony introduced Video Hi8 (short for high-band Video 8.) Like SVHS, Hi8 used improved recorder electronics and media-formulation to increase picture detail.

Quality:
In both systems, a higher-grade videotape and recording-heads allowed the placement of the luminance-carrier at a higher frequency, thereby increasing luminance bandwidth.

Both Hi8 and SVHS were officially rated at a luminance resolution of 420 horizontal TV/lines (566x480 in today's digital terms), a vast improvement from their respective base-formats of 240 lines and roughly equal to laserdisc quality.

The final upgrade to the Video8 format came in 1998, when Sony introduced XR capability (extended resolution).

Capacity:
The standard tape length is 90 minutes or 3 hours on long play.
