AJA FS4 Frame Sync and Up, Down, Cross-Converter

FS4 is a 4-channel 2K/HD/SD or 1-channel 4K/UltraHD frame synchronizer and up, down, cross-converter, and so much more. This combination frame synchronizer and converter offers incredible versatility and connectivity in a sleek 1RU frame for all your 4K/UltraHD and 2K/HD/SD conversion needs. FS4 offers a wide range of connectivity for both video and audio, including optional SFPs for single link 12G-SDI connectivity.  For HDR workflows, the FS4 supports automatic or configurable HDR metadata generation for the SDI output VPID and HDMI output HDR Infoframe.

In Four Channel Mode, FS4 can do the work of four separate devices in 2K/HD/SD or combine all processors and channels for maximum flexibility for 4K/UltraHD productivity in Single Channel Mode.

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
