New multi-monitors from Leader Instruments

New multi-monitors from Leader Instruments

Let me preface this post by saying that I'm a huge fan of Leader's products. The LV 5750 has been an indispensable tool on many of my engineering gigs and I'm really excited about the next evolution in the product line, the LV 5330 and LV 5380. While I think both these new scopes are very good, for me the price is finally right at around 6000 for the 5330. The 5380 which is a bit bigger and has a few more bells and whistles retails at around 10,000. I have a 5330 on order and should be getting it in the next few weeks. Once I have it, I'm going to do a post on how to correctly read waveforms and vectorscopes and how to identify skin tones on them. There are a few pages out there on this but nothing too meaty:

Helpful but not terribly in depth.

back to the scopes..

When I first saw these new highly portable Multi SDI Monitors at HD Expo here in NY, they seemed a bit like Astro clones but after delving in a bit I found that wasn't the case at all. On the outside, they look similar to the Astro - very sleek and light with well placed controls. The major difference being the Astro is an excellent monitor with SOME engineering features whereas the Leader is an engineering tool that also is an excellent monitor.  With the launch of these new products, it seems Leader is intentionally trying to get their gear out of engineering bays and monitor tents and on top of people's cameras. The 5750 was a pretty good start but at 5.5 lbs, it was a bit too beefy for on-board use.

A very cool new software has been developed by Leader called CineLite / CineZone and it comes bundled with the 5330 and is optionally available for the 5380. "CineLite" basically converts signal luminance to assigned f-stop values so if you like thinking about your images in terms of stops, this is a very helpful tool. Or if you're working with a DP who prefers communicating in stops, again this is a great feature. "CineZone" is very similar to the "Predator Vision" False Color viewing mode on the RED camera. Warm colors represent values approaching over exposure with white representing signal clip. On the other side, cool colors represent values approaching underexposure with black representing clip . Green is right in the middle representing zone 5, 18% reflectance gray. It's similar but a little more intuitive than Predator Vision which is a little confusing with how it uses varying shades of gray to represent middle of the range values.

This is kind of a crappy representation of it. When I get my scope, I'll post some better images.

a little sidenote: If you don't have this, it's a very handy thing to have. It approximately equates RED False Color to IRE values. I don't think it's completely accurate but it's still pretty helpful even if only to remind you where the gray values reside on the scale.

Here's a nice PDF of it for printing >>>

The LV 5330 and 5380 while sharing many of the same feature set are quite a bit different - the emphasis being on the portability of the 2.9 lbs 5330 vs. the versatility of the 5380. At 4.5 lbs, the 5380 isn't much smaller than the 5750 but in terms of what it can do, it's a pretty big advancement. The 5380 looks and feels more like a conventional LCD monitor to me than the 5330 with its relatively small 6.5" screen surrounded by engineering controls. The big 8.4" LCD on the 5380 can be laid out in any number of ways, displaying 1,2, 3, or 4 scopes/meters at a time. Despite it's larger physical size, it's actually the exact same screen in terms of resolution as the the 5330, a XGA TFT LCD 1024x768. Compared to the 800x480 resolution of a Marshall or Panasonic 7", there's a noticeably sharper and richer picture display. Both models also display highly accurate waveform (parade, Y Cb Cr, RGB, and pseudo composite), vectorscope (75% and 100% saturation), 8 channels of audio levels, 5 bar display for color gamut, and can screen capture to a USB drive. In addition they can both select and display a single line from the video signal and have comprehensive error detection, event logs, and data dumps. As I've emphasized before, scopes don't lie and there is no aspect of the video signal that can hide from these mofo's.

The key differences between the products are that the 5380 can be outfitted with a dual link HD-SDI board whereas the 5330 cannot. The 5380 can also display two SDI signals simultaneously. The 5330 comes with CineLite/CineZone installed whereas the 5380 strangely does not. Still scratching my head on that one... Also the picture display controls on the 5330 are somewhat limited with only the brightness, contrast, and saturation adjustable. There isn't even a "blue only" feature which I find really disappointing. I asked the guys at Leader about that and they said that the display doesn't need to be adjusted or calibrated because it displays the precise SDI signal. Well if that's the case, then why does the 5380 have total control over the display? Color Temperature, Brightness, Contrast, Gain, Bias, Selective Color Channels, etc... Obviously displays need to be tweaked all the time to account for varying degrees of ambient light. Color is equally critical and it would be nice if there was a way to quickly make sure they're accurate, ala' BLUE ONLY.

LEGACY BAGGAGE

LEGACY BAGGAGE

I've been researching this notion of Legacy Baggage and how it often unfortunately impairs the development of new technologies. 2 aspects of video production in particular are victims of this, namely - 2/3" sensors and 29.97/23.98 time code.

The size, 2/3", standard for broadcast camera sensors, lenses, etc. comes from the fact that prior to CCD technology, video cameras used a CRT pick up tube much like the one in your television. This pick up tube was 2/3" in diameter so the video lenses of the day were designed to work with this standard size. Due to the efforts of Sony, Ikegami, and others, eventually pick up tubes were phased out in favor of new CCD sensors. Given this opportunity to introduce a new broadcast video standard, the size of these new chips could have been anything but due to the existing equipment legacy, 2/3" was chosen so that all those thousands of video lenses out there could continue to work. It's the exact same situation with time code. Time code was originally a solid 30 fps. With the advent of color television back in the 1950's, the frame rate was slowed by 0.01% to become 29.97 which could accommodate analog color sync. Years later when 24 fps video production became a reality, the frame rate of 23.98 was introduced so that the new technology could fit into existing workflows. Now here we are again in the process of adopting a new 100% digital TV standard, where there are no analog related sync issues. HDTV broadcasts could quite easily utilize a solid frame rate and we would be done with 59.94/29.97/23.98 forever but instead, it was deemed easier and safer to make the new accommodate the old. Legacy Baggage.

Within reason, newer companies like RED and Vision Research have minimal existing equipment legacies to deal with so are therefore free to design with much less limitation. Take this new RED Digital Stills in Motion Camera idea. Unlike Canon, RED doesn't already have a pro video product line that would be rendered instantly obsolete with the introduction of this one product. (They do however have a certain 4k digital cinema camera that could be jeopardized, that is if they don't continue to support and develop it in its own right.) 

No legacy baggage = technological innovation

These are just some quick thoughts. It plays in with my earlier post on stills/video convergence. Just wondering where all this technology is leading us.. I'd love to hear what other people have to say about it.

Camera Alignment Workshop

Camera Alignment Workshop

I just attended a HD camera alignment workshop at Local 600 here in NY. Leader USA, the company that makes the scopes, was there demonstrating the correct way to camera match with their products. It's surprisingly simple if you know what you're doing and because there isn't a detailed paper anywhere online about how to actually do it, I'm preparing one for this blog. In the meantime, take a look at this - http://www.gonos.com/index_files/Page320.htm - it's very basic but it outlines the general procedure. It was provided to us by George Gonos from Leader Instruments.
