R3 2023

v1.7.8727.15888 — released 2023-11-23.

R3 2023 introduced the IBK 3D Keyer and a substantial overhaul of HSV Keyer (spill suppression, garbage matte, alpha gain), plus hardware-accelerated H.264 decoding via NVDEC and four new HSL blend modes. Rendering moved to separate threads for inputs, scenes, and targets.

Highlights:

• New IBK 3D Keyer — image-based keyer using a clean-plate reference.
• HSV Keyer overhaul — limit-to-key-color spill suppression, layer-based garbage matte (replacing the static-image one), spill luminance recovery, spill balance, function-key output-mode selection.
• Four new blend modes: Hue, Saturation, Color, Luminance.
• Hardware-accelerated H.264 decoding via NVDEC for media files.
• QuickTime Animation files with alpha-channel support.
• Web-page rendering with WebGL via Chromium.
• Separate rendering threads for inputs, scenes, and targets.

Operators

• New IBK 3D Keyer — clean-plate reference keyer.
• HSV Keyer — adjust chroma key in shadows and highlights for better edge results.
• HSV Keyer — new Limit to Key Color spill-suppression algorithm.
• HSV Keyer — spill luminance recovery and spill balance (RGB) controls.
• HSV Keyer — layer-based garbage matte (replaces the previous static-image-only model).
• HSV Keyer — Reset Alpha Gain and Alpha Ped commands.
• HSV Keyer / HSV Range Keyer / IBK 3D Keyer — function-key selection of keyer output modes.
• HSV Range Keyer — enable / disable garbage-matte support; simplified compute model for saturation and luminance.
• New blend modes: Hue, Saturation, Color, Luminance.

Inputs

• Hardware-accelerated H.264 decoding via NVDEC reduces CPU load on media files.
• QuickTime Animation files with alpha-channel support.
• Web-page input — rendering with WebGL via Chromium.

UI / Desktop

• Convert a scene layer to a precomp scene with operators preserved.
• Show input of selected scene layer via keyboard shortcut.
• Display input name as a tooltip when hovering a scene layer.
• Rename all layers using a particular input to that input's name.
• Reallocate missing media when file locations change.
• Confirmation dialog after loading a new media file.
• Warning displayed when opening a project with missing media.
• Delete added to right-click context menus, with confirmation prompts on inputs, operators, targets, and connectors.
• Auto-switch to the Inputs tab after media import.
• Tooltip icons on scene preview and layer icons.
• "Collapse all" for inputs and scenes.

Performance and monitoring

• Separate rendering threads for inputs, scenes, and targets.
• Extended Monitoring plugin gained an RTMP-target summary on the Prometheus endpoint.
• New metrics: composer_last_frame_processing_usage, composer_average_processing_time_10k_frames, composer_average_processing_usage_10k_frames.
• Server-Label tagging support for log entries.
• Runtime statistics for compute time over 10 000 frames.
• Updated performance-logging syntax with the new metrics.

Other

• Operators can access different scene layers within the same scene.
• Runtime version automatically saves settings on application exit.
• Version bumped from 1.6.x to 1.7.x.
