The 4-Channel 2K/HD/SD or 1-Channel 4K/UltraHD Frame Synchronizer from AJA offers incredible versatility and connectivity in a sleek 1RU frame for 4K/UltraHD and 2K/HD/SD conversion needs. Offering a wide range of connection options for both video and audio, this frame synchronizer can do the work of four separate devices in 2K/HD/SD or combine all processors and channels together for maximum flexibility for 4K/UltraHD productivity.

In single channel mode, the synchronizer will upscale your HD or SD materials to 4K/UltraHD and back, with a huge array of audio channels over Fiber, 12G or 3G-SDI, AES, and MADI for an incredible 272 x 208 matrix of audio possibilities. Enhanced Single Channel mode allows simultaneous output at 4K/UHD and downscaled 2K/HD/SD.

In four channel mode, it provides multi-channel conversion with up to 4-channels of simultaneous processing for 2K/HD and SD signals. The processing allows vide frame delay, ROI (Region of Interest) scaling, color correction, proc amp controls, motion adaptive de-interlacing, and much more.

The Rentex AJA FS4 with 12G-SDI includes the HDBNC-2TX-12G and HDBNC-2RX-12G Coax BNC modules, pre-installed for working with single-cable 12G-SDI signal flows as well as HDMI 2.0b, Quad-cable 3G-SDI 4K, and all other modes.

Format Conversion

Convert any supported input format to any supported output format, within the same frame rate family. These three families are:
- 59.94, 29.97, 23.98
- 50, 25
- 60, 30, 24

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
