Zacuto Gratical X overview

  • 1Description

The Zacuto Gratical X Micro OLED EVF is positioned as an entry-level version of the feature rich Zacuto Gratical HD. However, the Gratical X is far more than just a capability-limited entry-level EVF. The true advantage of the Gratical X lies in the many ways you can customize it, creating an EVF with only the features you want for a customized EVF that exactly suits your needs. However, you can also choose to upgrade it to the full version of the Gratical HD at your own pace as your needs require. In its base configuration, the Gratical X provides you a compact EVF that features a micro OLED panel about the size of your thumbnail with 5.5 million dots of resolution that produces an image with true blacks and a 10,000:1 contrast ratio. Both the HDMI and SDI inputs are enabled, supporting RGB signals at 24-bits for vivid color rendition, and featuring color bars, blue only setting for calibration, and display adjustments. Optional upgrades allow you to activate the loop-through outputs, LUT support, waveform and vectorscope displays, as well as focus and exposure tools such as peaking and false color. The EVF powers from a single LP-E6-type battery, and an 1800mAH battery provides approximately four hours of constant run time.

General Features

The 1280 x 1024 resolution of the OLED allows it to display a 1280 x 720 image and various diagnostic displays without needing to overlay the signals over the image. You can adjust the position of your image and displays to what suits you best, or you can also choose to overlay the diagnostic signals on the image.
With optional upgrades you can create and store LUTS within the EVF and apply individual LUTS to either or both the EVF display and the downstream video.
With optional upgrades the OLED display and outputs are independent of each other, which means you can display the video signal with one LUT on the EVF and send the video signal with a different LUT to an external monitor. Likewise, you can display the various test signals and diagnostic signals either on both the EVF on a downstream monitor or either one or the other.
Weather resistant covers prevent moisture or debris from getting in open ports.
Optional upgrades allow you to display audio meters in the EVF.
Optional upgrades allow you to display LUTs, test patterns, scope displays, and other display functions can be displayed in the EVF or simultaneously on the downstream video. You can select to have the EVF and the downstream video display different LUTs and/or display functions as well.

Optional Test Patterns & Diagnostic Signal Upgrades

  • The waveform provides an objective evaluation of your video signal. It displays the brightness of your image on an IRE scale, allowing you to see if your image will clip and where your black levels are.
  • The Vectorscope displays the signal on a graph so you can check the phase of your colors. The Vectorscope function also verifies and checks the overall tint and hue of an image.
  • The Historgram view allows you to see where your pixels are distributed in the spectrum of black to white, providing a quick way to see where your exposure values fall. You can choose to display the Histogram as either RGB or Luma.
False Color
The False Color feature provides under/over luminance warning by presenting the image as a series of color values representing exposure.
Peaking highlights the sharpest (most in focus) areas of the image with a color outline.
Provides a crawling black and white pattern overlaying areas that exceed the brightness levels you select.
Frame Store
You can store frames within the EVF to recall them at a later time. You can also adjust the transparency of the frame store and superimpose it on the current view when you need to align shots.
Test Pattern Generation
The EVF can generate color bars and a Macbeth color chart

    Zacuto Gratical X reviews

    Gratical X Micro OLED EVF is rated 4.3 out of 5 by 4.
    Rated 4 out of 5 by from Excellent hardware. Unquestionably, this is excellent hardware. It looks good, delivers a great picture and wow is it nice to have a 'real' eyepiece monitor on my C100. Overall, I am happy I bought it as it does allow me to really nail focus. The additional point of contact with the eyepiece against face also creates steadier images. That said - like everything else Zacuto - it is very expensive, dare I say, wildly overpriced. I understands quantity of scale, etc. but other companies are delivering things near in quality at a much lower price point. With this 'X', you need to pay for any additional features you want. The classic bundle covers a few things (scopes, white peaking - which adds a slight white edge to things to help with focusing, looks a lot like sharpening an image) - but if you want Zebras and red peaking for focus, etc. -- It's gonna cost you. A lot. wow. My biggest complaint and concern with the Gratical viewfinders is that via HDMI, it is NOT currently possible to see a record light or TC in the monitor - whether you're willing to pay for it or not. THIS IS HUGE! Without that info, it is impossible to know that you're actually recording, unless you look to another monitor or tally light. I KNOW there is a way to get this info from an HDMI signal - as Atomos has done it with their devices (at least with data sent through HDMI by Canon cameras). Hopefully, the good folks at Zacuto will get this figured out really, really, really soon. It severely limits the comfort/trust factor when shooting. Other than that - good stuff.

    Rated 5 out of 5 by from Expensive but Essential.. I have been looking at this product on the internet for the past year and really wondered if the image quality was really worth the asking price. Like most expensive high end products, benefits in performance/quality don't always justify the price tag they command-yes, they do have performance benefits but only incremental. Not so with the Gratical..It was like having my cataract removed-really. I use a Sony FS5 and so I bought only the scopes and the pixel magnifier. I use the zebras from the FS5 and they work great. Let me mention that I could not get my hands on one prior to the purchase, to see for myself what I was buying..but took the risk anyway.. I hope this helps.. Ajit

    Rated 4 out of 5 by from Absolutely essential A good EVF is absolutely essential for judging contrast and exposure. I've used my Gratical on several cameras and it's an absolute must have for me. My favorite features are the non colored edge peaking, scopes and LUTs. Of course its a drag to have to pay for these separately but you can wait till Zacuto has a 30% off sale and you only need to buy the features that your camera doesn't already output. The only issue with these is that they will eventually develop screen burn from whatever overlays your camera outputs. It's a drag but I still love these EVF's.

    Rated 4 out of 5 by from Image is so clear you don't need redline peaking for focusin I got this as an upgrade to my Zacuto EVF. The OLED screen is amazingly sharp! So much so that you don't need any focus assist like redline peaking. Love that it has input/output options. Certainly helps me to keep it future proof. The only downside is that the screen isn't as large as I'd like particularly compared to the big, beautiful picture the EVF had. I did purchase the redline peaking for extra confidence in grabbing focus but I did like how that feature worked in the EVF better. Overall, it delivers on all the promises.
