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.
- 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.
