v1.5.0
89c5cff

KnoxStudio now runs on GPUI + gpui-kit instead of egui/eframe. The NLE, capture, export, and AI domain stay the same; the window runtime is a retained-mode Mac app.

Runtime

  • GPUI with gpui-kit: GPU-composited window, native TitleBar, resizable splits, overlays, and semantic light/dark theme
  • Native macOS application menu (KnoxStudio / File / Edit / View / Playback / Window / Help) with system Undo, Redo, Cut, Copy, Paste
  • Finder, Dock, and open file events through GPUI on_open_urls — no vendored winit patch
  • Session split into independent entities: Document, Workspace, canvas, timeline, Inspector, Agent, Screenplay
  • Playback clock advances the playhead without rebuilding Inspector, Agent, or chrome every display refresh; canvas and timeline request their own animation frames
  • Custom GPU Elements for the preview canvas and the timeline (hit-testing, paint, thumbs, waveforms)
  • Screenplay editor on the kit rope Editor: Tree-sitter highlighting, line numbers, soft wrap, find/replace, outline, and git
  • Agent composer is a real textarea with @ mentions, decorations, and streaming markdown — not a per-frame egui text edit
  • In-app FPS HUD (gpui-fps) from GPUI frame timings: FPS, frame time, P95, drop rate, CPU / GPU / memory
  • Dedicated tokio runtime so AI, export, and IO never block the UI thread
  • Bundle FFmpeg/FFprobe 9.0.1

What this unlocks

  • Native Mac chrome: traffic lights, menus, and OS edit actions instead of a painted-in title bar
  • Smoother preview while playing: only the surfaces that show time (canvas, timeline, meters) tick
  • A Zed-class text substrate (rope + Tree-sitter + LSP types) for screenplays and a future coding agent
  • Observable session state (entities + subscriptions) as working memory for agents and checkpoints
  • Drop the eframe/winit activation workaround that existed only to keep bundled-app file-open correct

Still the same product

Capture, timeline editing, Inspector, Voice Director, generation, export, OAuth, and autosave are the 1.4.x feature set on the new runtime. Domain Criterion benches (project_benchmarks) are unchanged; they measure project JSON and timeline ops, not GPU frames.
