Frage von Hubert:
Hello,
I feel that such an idea by the head, but now I'm searching since days in the internet, and apparently nobody has done, or at least not reported.
I own an older semi-professional S-VHS camcorder, an Explorer Philips VKR-9500 (baugleich. JVC GF-S 1000).
the device actually makes pretty good shots, and I have neither the money nor desire any major camcorder to see what small digital part to replace. I like the big vollformatkamera on the shoulder.
in the last time I play but I always thought öfer with the broadcast-in quallität recorded. SVHS is now in fact with its 400 linienparen absolutely not bad (according to the manufacturer creates the SVHS)
But any fundamental so it must have the professionals even obsolete U-MATIC SP system with the theory, its 300 lines makes even less than s-vhs prefer.
SVHS as vhs 2 weaken. the first is undoubtedly the farbunterträger, with the reduced bandwidth is directly recorded.
what the reason is that the chrominance a much lower resolution than the brightness signal.
Here is our eye, as it were betrayed.
because I did not before the entire vhs system to re-develop it, you can sadly nothing changed.
But what you have to hire what can change is the second weakness of the VHS / SVHS systems.
the weakness which I read is the high density in the band.
vhs and the course synonymous with the S-VHS system, the tracks on the band directly side by side without any gaps (so-called "grass")
This is a talk about between the tracks. Now the FM modulated luminance signal can be happy not to disturb, but it very well like I said chrominance not fm modulated, but with reduced bandwidth directly recorded.
so-called cross-color effects are the visible result of this crosstalk.
with each copy of these effects reinforce each course, and obviously the color synonymous.
for some devices, it is synonymous to a bleed of color.
a little maybe you could do would be the band to increase speed. so would the tracks on the band no longer directly adjacent to and something they would "race" to win.
least disruption caused by the talk about the tracks, should thus be eliminated.
Although this was the chrominance still not a better resolution.
Nevertheless one would enable the recording quallität significantly increased.
the further processing is running in digital s.PC me anyway, so it is hard to generation losses by repeated copying.
and actually is my quallität materials synonymous absolutely not bad, but even better would be nice :-)
you can see that very clearly when I directly with the computer of the camera recordings, ie without a band on record. the quallität imen is good. absolutely compatible TV.
with the station between the svhs.band ists still good, but the difference can be seen in direct comparison very much.
But since I usually take it on, I come to the recording on a tape is not around.
how is this - what do you think of this idea of the speed band of the s-vhs to increase drive.
times assumed you doubled the speed tape, it could be on a cassette 240er still 120 minutes of video recording. ne is the camera for more than enough
The only question is how one starts, it should theoretically be assigned to the control of the motors capstans modify, and where appropriate, a einbaun switch between standard and double speed.
has anyone of you ever done something?

Antwort von Andreas_Kiel:
Moin,
if succeeded, it would then not synonymous, the head drum rotate faster? I'm trying to me with the belt speed to present times: with a constant drum speed would be only the oblique angle of the flat track record, the single track would be longer, but at the
distance of the tracks would be no change, right?
The strap material should be significantly more synonymous endure.
But more interesting approach ... my old S-VHS recordings are still relatively good. Perhaps the soldering iron a gifted virtuoso times implement and report ...

yes, unfortunately, are the most video systems for the consumer market without rasen on. except video8/hi8 at least in standard play (SP) is characterized video8 actually with a small lawn between the tracks on.
Unfortunately I have no goldesel, otherwise I would be pretty NEN Betacam SP cancorder growth.
I certainly synonymous going to do next week if I win the lotto (vorausgesezt I vegesse not to play)
ok ... fun aside.
as I said I like my camcorder. the objective is anything s.schlecht, and the size and the enormous weight, I feel rather than a positive disadvantage.
and when I think about how many d-mark I was on the camcorder to the table scrolls have, I still dizzy.
improve the signal to noise ratio, a color by the veringerung enlarge the distance between the tracks is exactly what I want. that's the only thing you increase the speed to reach DEWR band "could"
I can pretty well synonymous with the soldering iron umgehn, and to some degree synonymous schlatungen read. whether I achieved this conversion alone would? no idea, but I know some hobby electronics should have the right.
I am only interested in whether somebody already has tried and with what results.

for some devices, it is synonymous to a bleed of color. The Color of Aubluten is VHS systems perfectly normal ...
"However, such low frequencies tend to crosstalk, which is why in very densely packed formats such as VHS default noise reduction is integrated, which should minimize the color. This leads to several generations of a" bleeding "of colors." Source:
Antwort von Jens W.:
Hello,
This topic is older, but I'm in the search for information about the Explorer VKR-9500 and rise to the following sentence gestolpert:
"you remember that very clearly when I directly with the computer of the camera recordings, ie without a band on record. imen the quallität is good. perfectly compatible TV."
I'm interested in how it works, without the tape directly on the calculator incorporated. If the signal s.AV-out from the chip?
Schon mal Danke even if it arrives ...

Somehow I have a weak memory from my picture technician training s.der SRT, the man told us, Beta is just a format without a lawn that would be synonymous and the importance of the Japanese term, it sounds like the beta. (Since I am but just in Directing in DU sit, I approached s.meine documents.) But, of course, Beta SP is beyond doubt.
