AJA FS-HDR Real Time HDR/WCG Conversion with the Colorfront Engine™ Video Processing

The AJA FS-HDR is a universal converter and frame synchronizer purpose-built for High Dynamic Range and Wide Color Gamut work, delivering real time, low latency processing for broadcast, OTT, production, post, and live event environments. Developed in partnership with Colorfront, it applies the Colorfront Engine's proprietary video processing algorithms to preserve color fidelity across 4K/UltraHD and 2K/HD workflows.

Single Channel Mode provides up, down, and cross-conversion to 4K/UltraHD, while Four Channel Mode runs four independent 2K/HD HDR/WCG channels in a 1RU frame. Conversions span HDR to HDR, HDR to SDR, and SDR to HDR in BT.709 and BT.2020, with camera formats including Sony S-Log3, ARRI Log C, Panasonic V-Log, RED Log3G10, and Canon Log 2 and 3 brought into the HDR space alongside BBC HLG, NBCU, user, and dynamic 3D LUTs.

• Scaling Supported in 2K/HD/SD formats Zoom in and out Reposition Region of Interest (ROI)
• Up-Conversion Hardware 10-bit Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image with black side bars Zoom Letterbox: results in image zoomed to fill fullscreen Zoom Wide: results in a combination of zoom and horizontal stretch to fill a 16:9 screen; this setting will introduce a small aspect ratio change
• Down-Conversion Hardware 10-bit Anamorphic: fullscreen Letterbox: image is reduced with black top and bottom added to image area with the aspect ratio preserved Crop: image is cropped to fit video output format
• Aspect Ratio Conversion for SD to SD Letterbox: Transforms SD anamorphic material to a letterboxed image H Crop: Produces a horizontally stretched effect on the image; transforms anamorphic SD to full frame SD Pillarbox: Produces an image in the center of the screen with black borders on the left and right sides and an anamorphized image in the center V Crop: Transforms SD letterbox material to an anamorphic image
