BoxIO Lite SDI

Advanced Color Management

BoxIO Lite SDI is an advanced color management device designed for both color critical post production environments and demanding on set color management applications.

BoxIO Lite SDI supports both 3D and 1D LUTs for unparalleled image control. BoxIO Lite SDI can be used for calibration, on set grading, and other LUT based operations.

On Set Grading

BoxIO supports real-time LUT updates over IP allowing for direct integration with popular on set color management tools like Pomfort's Livegrade Pro, QTAKE’s Grade module, Filmlight's Prelight, and Assimilate Live Assist and Live Looks.


Camera Metadata

Livegrade Pro 4.1 has the ability to read camera metadata from SDI signals connected to BoxIO. Compatible with ARRI, Panasonic, and Sony cameras.

HDR Workflows

BoxIO is uniquely well-suited for HDR workflows thanks to 4 key features that are not typically found in combination on other devices:

33x33x33 3D LUT support

Twice the data points of devices with 26^3 3D LUTs and over 7 times the data points of devices with just 17^3 3D LUTs

4096 entry point 1D LUTs both before and after the 3D LUT

Many LUT devices offer no 1D LUT support or only support 1D LUTs or 3D LUTs, but not a combination of the two. The few devices that do offer 1D LUT support typically only offer 1024 entry point 1D LUTs in a single position, either before or after the 3D LUT.

Tetrahedral LUT interpolation

Trilinear LUT interpolation, found on many LUT devices, can be particularly problematic in HDR workflows. Tetrahedral LUT interpolation can provide significantly improved accuracy and visual performance.

Full 12bit 444 signal support

Many LUT boxes limit support to 10bit signals, but some HDR specifications are specifically optimized for 12bit signal paths.

Frame Capture

BoxIO supports frame capture over IP allowing select applications including FSI’s IP Remote Utility and Pomfort’s Livegrade to grab reference still frames from incoming video signals.

Frame Callback

Frames captured in BoxIO’s own .RAW format from the IP Remote Utility can be displayed using Frame Callback. This feature has many potential uses including review of reference stills in on set environments, display of complex test patterns, and preview of new looks on previously captured content. Frames can be loaded quickly from a connected computer or directly from 16 available memory slots on BoxIO for even faster frame recall.

Pomfort’s Livegrade Pro and Livegrade Studio also support Frame Callback functionality without the need to first capture in BoxIO’s RAW format. You can simply display a shot’s graded still image (or thumbnail frame from a recorded movie) on any connected BoxIO device. By toggling the frame callback on/off, you can conveniently compare a look from your shot library with the current live signal. This way, you transform BoxIO into an SDI output device for reference still frames with just a few clicks.

IP Remote Utility

The IP Remote Utility provides useful toggles and controls for management of your BoxIO and can be used in conjunction with other applications from FSI’s software partners.

Quickly change mode and channel settings, load LUTs to BoxIO, toggle LUTs on and off instantly, update, manage BoxIO IP and WiFi settings, and capture frames at full resolution that can be saved instantly as a .JPG or .BMP


Waveform and Vectorscope transmitted directly from your BoxIO to your computer with no additional equipment needed. Simply connect your BoxIO and computer to the same network and use the IP Remote Utility. ScopeStream is also directly integrated in Pomfort’s Livegrade Pro allowing you to view BoxIO generated Waveform and VectorScope without having to leave the application.


BoxIO Lite SDI comes equipped with 1 x 3Gbps SDI input, 1 x clean SDI loop through, and 2 processed SDI outputs.

Clean loop through SDI output mean BoxIO Lite SDI isn't limited to being an "end of chain" device.

All inputs and outputs offer full 12bit signal support.

Communicate with external devices over LAN, and WiFi.

BoxIO Lite SDI features a 4pin mini-xlr connector supporting 12V to 18V power and draws less than 10W of power.

Single-Channel Mode

BoxIO Lite SDI can operate in a single-channel mode. This allows a LUT to be applied on both processed SDI outputs so that your signal can be distributed to multiple locations from a single BoxIO. In single-channel mode BoxIO supports 33x33x33 size 3D LUTs.

Dual-Channel Mode

Two LUT Boxes In One.
BoxIO Lite SDI can apply two separate LUTs to a signal at the same time essentially operating as two LUT boxes in a single device. In dual-channel mode each channel supports 17x17x17 size 3D LUTs.


Store up to 16 33x33x33 size 3D LUTs and easily toggle between them.


Store up to 32 individual 17x17x17 size 3D LUTs (16 per channel) and easily toggle between them.

Advanced LUT Processing

BoxIO processes 3D LUTs using tetrahedral LUT interpolation allowing for a much higher degree of precision with better visual performance than less advanced trilinear LUT interpolation.

An effective way to understand the performance benefits of tetrahedral LUT interpolation is to compare the necessary average 3D LUT size for equivalent performance using each interpolation method.

Average 3D LUT Performance Equivalency Between Interpolation Methods
Interpolation Method Tetrahedral Trilinear
3D LUT Size 17x17x17 22x22x22 would be required
33x33x33 43x43x43 would be required

Have a display that doesn't offer built-in 3D LUT based calibration? BoxIO interfaces directly with the industry's leading calibration software solutions for simple and accurate 3D LUT based display alignment.

Specially priced versions of Calman and ColourSpace for FSI are available. BoxIO will also work with fully licensed versions of Calman Studio and ColourSpace CMS.

Test Patch Generation

BoxIO is equipped with an integrated test pattern generator allowing for manual test patch generation from the BoxIO Utility or automated test pattern generation from calibration software like ColourSpace or Calman. Perform 3D LUT based calibration quickly and easily with BoxIO, a probe, and ColourSpace or Calman.

Direct Upload

Upload LUTs generated from ColourSpace CMS and Calman software directly to BoxIO without exiting or running additional programs.

Compact And Silent

BoxIO’s fan-less all aluminum design is durable, quiet, and built for 24/7 operation.

Up to 4 BoxIO units can be mounted in a single RU with available rack mount.
