Added HDR Upconverter AI - FabCloud version that requires no device performance specifications.
Top-Tier SDR to HDR Conversion: From Rec.709 SDR to True HDR10 & Dolby Vision
Move beyond basic upscaling and washed-out filters. As the industry's first mature AI SDR to HDR converter, UniFab uses Deep Neural Networks and AI Inverse Tone Mapping (ITM) to up-map standard Rec.709 SDR footage into true 10-bit HDR — intelligently reconstructing the luminance data that SDR loses. The result: authentic SDR to HDR conversion that delivers flawless Rec.2020 color fidelity, real HDR10 brightness, and automated Dolby Vision with scene-by-scene dynamic metadata — all at industry-leading speeds on local GPU or FabCloud.
Convert SDR to HDR in the Cloud — No GPU Required
No high-performance GPU? No problem. UniFab is the only AI SDR to HDR converter that lets you choose between local processing and cloud processing via FabCloud. Just upload your SDR video and FabCloud handles the heavy AI Inverse Tone Mapping — converting SDR to HDR in the cloud, with no hardware upgrades, no driver issues and no device limits. Works on any laptop, even older Macs and low-end Windows PCs.

Convert SDR to HDR with AI-Driven Inverse Tone Mapping
Standard SDR video is locked at 8-bit color, ~100 nits peak brightness and a narrow Rec.709 gamut — that's why SDR looks flat and washed out.
UniFab's AI SDR to HDR converter goes far beyond basic enhancement: trained on massive SDR-to-HDR paired datasets, our Deep Neural Networks perform Inverse Tone Mapping (ITM) on every frame, reconstructing the luminance data SDR throws away and re-mapping pixels into 10-bit HDR with up to 1,000-nit highlights and a wide Rec.2020 / DCI-P3 color volume. The result is genuine, artifact-free HDR — not a fake "boost contrast" filter.

HDR10 & Dolby Vision: Cinema-Grade SDR to HDR Output
Our SDR to HDR Converter outputs both cinema-grade HDR standards — HDR10 and Dolby Vision — for streaming, gaming and 4K Blu-ray workflows.
✨ HDR10: 10-bit color depth, up to 1,000 nits peak brightness — the most universally compatible HDR format across TVs, monitors and consoles.
🎬 Dolby Vision: Up to 12-bit color depth and 4,000 nits with scene-by-scene dynamic metadata — the premium HDR standard used by Netflix, Disney+ and Apple TV+.
System Note: An HDR-compatible display is required to fully experience HDR-enhanced content.

Two Color Spaces for SDR to HDR Conversion
UniFab's SDR to HDR conversion engine outputs into both wide-gamut color spaces — DCI-P3 and BT.2020 / Rec.2020 — for accurate HDR color on every display.
🎨 DCI-P3: The cinema standard. DCI-P3 covers ~45% wider colors than Rec.709 SDR, perfect for HDR monitors, gaming consoles (PS5, Xbox Series X) and creators editing for streaming platforms.
📺 Rec.2020: The UHD broadcast standard. Rec.2020 (also called BT.2020) covers ~75.8% of the visible color spectrum — almost double the coverage of Rec.709 SDR — making it ideal for SDR to HDR film mastering, 4K Blu-ray production and high-end home theaters.
Note: Advanced devices and processing power are required to fully utilize Rec.2020.

Unlike fake-HDR filters that just push contrast and saturation, UniFab is a real AI SDR to HDR converter. It uses AI Inverse Tone Mapping (ITM) to analyze each frame, reconstruct missing luminance, expand the dynamic range from ~100 nits SDR to up to 4,000 nits HDR, and re-encode the result as true 10-bit / 12-bit HDR (HDR10 or Dolby Vision).
