The only AV1 frontend with HDR-VDP-2, VDP-3 and ICtCp perceptual metrics. Pure C, single EXE. Designed for Topaz Video AI workflows.
VMAF, SSIM, PSNR for standard analysis. HDR-VDP-2 and VDP-3 for human visual system modeling. ICtCp delta-E for HDR color fidelity. All frame-accurate, GPU-accelerated via CUDA cuFFT.
Auto-align to 8px multiples for SVT-AV1. Each algorithm scored on 7 criteria across 3 contexts. Compare BEFORE/AFTER at up to 32x zoom.
Logarithmic HDR waveform from 0.1 to 10,000 nits with MaxCLL/MaxFALL references and P10-P90 luminance spread. CIE 1931 chromaticity with BT.709/BT.2020 gamut triangles. Four mitigation modes.
Real-time CCD topology for AMD Ryzen. Per-core MHz and temperature with heat-gradient visualization. AMD Ryzen Master SDK and HWiNFO64 shared memory. Assign Chromaster to a dedicated core while workers encode on the rest.
Select your display, content type, and quality tier. Chromaster auto-configures CRF, preset, psychovisual enhancement, variance boost, quantisation matrix, and more.
Mantiuk et al. perceptual difference predictor in pure C. Multi-scale Cortex decomposition, CSF per band, photoreceptor model. Dynamic CUDA/cuFFT.
BT.2100 PQ to LMS to ICtCp perceptual space. Per-pixel distance with LUT-accelerated EOTF/OETF and bilinear 4:2:0 chroma upsampling.
Direct3D 11 GPU compositing. Direct2D + DirectWrite vector UI. CPU framebuffer BGRA8 for waveforms and CIE rasterization. Zero GDI+.
Topaz Video AI chain preserved as MKV tags. Chromaster encode parameters as structured JSON. Full command and QA log in container.
Frame difference analysis with configurable threshold. Magnetic cursor snaps to scene boundaries. HDR-aware scene navigation.
Command injection mitigation. Centralized metacharacter filtering. Input sanitization, index clamping, fread validation, UTF-8 safe.
