Kona 3 needs a Waveform Vectorscrop…please help…

[Bob Zelin]

The least expensive solution is to simply buy the Panasonic BT-LH1700W or the larger Panasonic BT-LH2600W LCD monitors, that have a built in waveform monitor function, that appears in a “quarter screen” overlay on the LCD picture monitor. The quality is not great, but it does work, and is very functional for many people. It will display for SD and HD. This is the least expensive solution.

A better stand alone solution is the Leader LV7700, which is an autosensing SD / HD waveform monitor/vectorscope that uses a VGA monitor to display it’s image. It’s about $7000, and is teriffic, and is the cheapest stand alone HD scope on the market.

If you just need SD (no HD), the cheapest solution is the Videotek VTM-150, which also uses
a VGA montior to display it’s signal. About $4000.

Solutions from Tektronix, and Magni are much more expensive. The new Harris/Videotek line is VERY expensive -HD monitoring starts at over $12,000.

The cheapest Astro systems scope is $9000, and is a piece of crap. And the Hamlet HD scopes are a joke, even though they are only $6000. The resolution is terrible, and their staff seems to have no idea of how to use their own products.

So, what can you get for $2000, that can display an HD signal – NOTHING !!!!!! (see – a product idea for someone out there !).

You will find that when people say “hey, I heard about this product, I heard about that product” – that they are all EXPENSIVE.

As Bob notes, a good cheap HD Scope starts at $12,000. I priced them last year and they haven’t dropped much. There is one from England that starts around $6,000 but it does not have a very good display and is very hard to read.

Bob’s suggestion of the Panasonic display is not a bad idea.

As an alternative I purchased Final Touch HD which is a color corrector and has completely accurate scopes along with a beautiful broadcast safe filter. $5,000 got me accurate scopes and a color corrector.

The CompuVideo scope is a PIECE OF CRAP, it is worse than the Hamlet HD scope that I badmouthed in my post on this subject. CompuVideo is a guy from Brooklyn that used to fix VTR’s in NY. He found some Asian company that makes cheap Oscilloscopes, and modifies them so they can act as a waveform monitor. As the years went on, he kept making new input boards (probably sourcing them) to convert SDI and HD-SDI to composite to display the signal on the Oscilloscope. If any of you have ever had any electronics courses, you may have seen what an oscilloscope looks like – with lots of knobs for vertical amplitide, horizontal timebase, trigger controls, etc. ALL OF THESE USELESS AND CONFUSING controls are on all the CompuVideo products – because they are OSCILLOSCOPES – not dedicated waveform monitor/vectorscopes.

If I had a gun held to my head, and I had to choose between the Astro Systems, Hamlet and CompuVideo, (all terrible products), I would choose the Astro Systems or Hamlet in a HEARTBEAT before the CompuVideo scope for professional video applications.

Again, professional scopes come from Leader, Tektronix, Videotek, (and built into the Panasonic LCD BT-LH series), and functional but not great scopes come from Hamlet and Astro Systems, but the CompuVideo product is an oscilloscope, not a waveform monitor – no matter what their product info says. You can get any Tektronix oscilloscope to show a waveform display – put an AJA HD-SDI to composite converter in front of it, and it will show an HD waveform signal.

As I am sure Mr. Deadhead knows, the Greatful Dead were very adamant about using the finest equipment. They were the first to use Meyer Sound for sound reinforcement, and of course, Alembic guitars – nothing but the best for them. As should be for Mr. Deadhead – nothing but excellent equipment in your career.

You’re such a geek. (That’s a major compliment…read on) I spent years reading your forthright posts on the AVID-L, all very entertaining reads. Glad you lurk here at the COW ’cause I look you up once in a while to see what’s on your mind. Your input to this thread is proof that you are a valuable asset to this place.

So why don’t you dig up a digital photo of yourself and send it to Ron and Kathlyn and make yourself a host of one of your favorite forums.

If I ever read of someone needing an HD scope, I’ll send them this thread link, for sure.

I know Ron and Kathlyn, and they are not fools – they would NEVER want someone as volatile as me as a “host” on a forum that generates income for them. I am every manufacturer’s worst nightmare.

Aloha Bob,
I know Ron and Kathlyn, and they are not fools – they would NEVER want someone as volatile as me as a “host” on a forum that generates income for them.

But your replies make great reading, both for information and commentary, at least when they’re not directed at me:)!

And the Grateful Dead were great tech heads. My ex-wife was a sound engineer with a big concert company and I got to hang out in the Grateful Dead sound booth at one concert where their engineer showed me how they used FFT’s to do noise cancellation at each venue by setting up a network of microphones. They had all the setups on a computer. The FFT computer was classified at the time (around 1990) and they couldn’t take it to foreign countries as it was used by the Navy for noise cancellation in submarines or some such thing.

Aloha,

Ken
