Zacuto’s new Gratical HD packs a lot of computing power for an electronic viewfinder, with a powerful dual-core FPGA processor allowing for added functions (such as focus assist) and customisation.
It also has a 4:3 1280×1024 Micro-OLED display with an extended contrast range. When the top part is used as a 16:9 1280×720 HD display, there is plenty of room for waveform, histogram, vectorscope and other data. Zacuto had experimented with a full 1080p OLED, but it didn’t make a visible difference at that scale and would have been much more expensive.
It has HDMI 2.0 (for 4K) and HD-SDI in/out, and can cross-convert HDMI to HD-SDI. It can also import, export and create look up tables, and users can have separate LUTs in use for both the viewfinder and the HD-SDI output to another monitor or video village (which can also view different scopes to the EVF). The LUTs can be saved as presets and exported to software like Resolve.
It is self-powered (battery), has an Arri rosette on the side for easy mounting, and users will be able to buy custom camera cables, allowing it to show the same on-screen data as the camera’s own display.
