The NovaStar HDR Master 4K video processor converts between SDR and HDR10/HLG formats and provides 4K video input, scaling and output. It is intended for signal-conversion workflows where sources and downstream display equipment require different dynamic-range formats.

SDR and HDR conversion workflow
Select SDR, HDR10 or HLG output to match the receiving equipment. The processor provides output color-space, sampling-rate and bit-depth adjustment, plus input black-level, output contrast-gain and low-grayscale-gain controls. Final display results depend on the source, settings and downstream HDR capability.
SuperView III provides content-adaptive scaling. Image mosaic, cropping, layer masks and flipping support the required screen composition.
Cards, optical outputs and graphics
The two output cards carry the same synchronized picture, not two independent programs. Import background and logo files through a USB drive. The stated graphic width and height limits are separate dimensions; check the accepted file format and size in the manual.

HDR Master 4K FAQ
Can HDR Master 4K convert SDR content to HDR?
Yes. It supports conversion from SDR to HDR10 or HLG. Configure the output for compatible downstream equipment.
Can it also convert HDR to SDR?
Yes. HDR10 and HLG content can be converted to SDR output.
Can the two output cards show different programs?
The listed output-card arrangement sends the same content synchronously from both cards.
What video input connections are provided?
The pluggable input card has one DP 1.2, one HDMI 2.0 and four 12G-SDI connectors, with up to six simultaneous 4K × 2K at 60 Hz inputs.
Can I import a background or logo?
Yes, via USB. The listed limits are ten backgrounds and ten logos, with maximum width or height of 8192 pixels for a background and 512 pixels for a logo.
