Introduction
Void Video is a professional real-time video processor designed for home theater and projector setups. It captures live video from Blackmagic DeckLink cards, processes it through a GPU-accelerated rendering pipeline powered by libplacebo and Vulkan, and outputs the result to a connected display.
The application runs on Linux and is controlled via an on-screen menu (keyboard or remote) or a web-based remote control accessible from any device on the network.
Key Features
- Upscaling and downscaling with research-grade resampling filters (EWA Lanczos, Catmull-Rom, Hermite, and many more), plus configurable frame mixing for temporal smoothing
- HDR tone mapping from PQ/HLG to SDR or remapped HDR, with scene-adaptive metering, histogram analysis, and custom tone curves
- Color management including output gamut selection (BT.709, BT.2020, Display P3), transfer function control, and perceptual gamut mapping
- Geometric warping for projector alignment -- keystone, barrel/pincushion, trapezoid, corner pin, and edge adjustments
- Cinema zoom with constant-image-height helpers, non-linear stretch, and automatic black bar detection
- Display management with automatic refresh rate switching and display mode whitelisting
- Real-time performance at up to 4K120 with deferred GPU decoding and lock-free frame queuing
