Just thought I`d throw in my 2 cents worth for the guy and others that get
confused when hearing about TV resolution!
The Vertical resolution of a broadcast NTSC signal is limited too about 330
lines of vertical resolution. The NTSC signal contains 525 horizontal scan
lines but these are different than the vertical lines that are used to rate
different video products. Vertical resolution is the number of VERTICAL lines
that a TV, VCR, CAMERA can display/record before they begin to blur together.
A plain TV and VHS sets can only show about 240 lines of vert res. One of
the 'Monitor' type of TV sets (ones that claim 330 to 560 or more) or the
only ones where you actually see the full quality of broadcast (330 lines)!
Beta VCR's have a slightly better resolution (about 250) than VHS.
Then theres ED BETA (ED for Extended Definition) and S-VHS (Super VHS) that
can record over 400 lines of ver. res. Of course your source has to provide
that many lines. So then you'll only get 330 lines if your broadcast signal
is ideal. Now there are S-VHS camcorders (maybe ED Beta camcorders too?) that
will allow you to record better than broadcast! Another catch is you need a
Monitor set that will take the seperated chroma and luma signals so you'll see
all those lines! (Luckily the Commodore monitors have those seperated inputs!)
While I'm here…the 8mm video format is capable of 330 lines BUT they haven't
found a way to cost effectively manufacture a tape that will do the job so they
are limited to about 240-260 ver. lines. Oh, theres a new video format coming
this fall, it will be 8mm Hi-Band! Supposedly over 400 lines too!
Then sooner or later there will be HDTV (High Definintion TV!) (600-1200 lines!)
I have no idea what the resolution is on the 1080,1084,2002 monitors but the
resolution of the video signal must be at least 330 lines in order to get the
broadcast quality needed for Desktop Video! So remember, if you use a plain
Beta, or VHS ,or 8mm you'll lose a lot in quality but its more than adequate
for home use.
By the way…a VHS with HQ (High Quality circuits) does NOT add any apparent
