- Here are the specifications on image elements of VHS, S-VHS, 8mm, and Hi8mm
- formats...
-
- VHS S-VHS 8mm Hi8mm
- ------ ------ ------ ------
- CHROMINANCE 629kHz 629kHz 743kHz 743kHz
- LUMINANCE 1.0MHz 1.6MHz 1.2MHz 2.0MHz
-
- As you can see Hi8mm has more signal frequency deviation than 8mm. In theory
- more signal frequency deviation means a better image.
