v1.5.9

UI

Added

• Inline data: images in Markdown and HTML
• System Reduce Motion on macOS, Windows, and Linux (Accessibility → Display), so caret blink, streaming dots, and kit animations honor the OS setting
• Chart hover that fades out after the pointer leaves a data point
• Scroll bounce, streaming-text fade, and touch text-selection handles from the UI kit

Changed

• Improved real-time voice interaction
• Dialogs shrink to stay inside small windows instead of running off the edges
• FPS HUD uses the display refresh rate as its frame budget (a 120 Hz ProMotion screen is graded at 8.3 ms, not 16.7 ms)
• A hidden FPS HUD stops tracing frames; the HUD's own redraws are left out of the readings
• macOS Reduce Motion is read from the system API instead of a defaults subprocess
• Startup model catalogs: the chat, video and audio catalogs, plus the voices list, now load in parallel instead of one after another. That was about 20 seconds of sequential network waits. They also share one HTTP client, so connections are reused.
• Agent chat list: the list of visible messages is now computed once per render. Before, it was recomputed for every row, which slowed long conversations.
• Hardware encoding took the same time as before and about 20–30% less CPU.

Fixed

• Recording camera

v1.5.8

Timeline

Added

• Drag a clip above, between, or below tracks to create a new lane
• Insertion bar that shows where the new track will land
• Auto-scroll while dragging near the top or bottom of the track list
• Drag track headers to reorder
• Resize track height from the header edge
• Overwrite edit mode
• Option-drag to copy a clip onto another lane or a new track
• Magnetic tool to close gaps after a move
• Option-drop to replace a clip with incoming media
• Shift-lock a drag to time only or track only
• Shortcuts to add, delete, and move tracks

Changed

• Dropping or placing media on occupied time creates a new track instead of stacking
• Empty tracks are removed after you move their last clip away
• New video overlays sit above; new audio sits below
• Detach Audio fully splits picture and sound so they edit independently
• Snap is now edge snapping; magnetic gap-close is its own tool

Media Library

Added

• Permanent Delete (⌘⇧⌫) with a confirmation that lists names; not undoable. Backspace still moves to Trash
• Restore File on git-dirty screenplay files, with a prompt
• Open in Terminal (⌥⌘T)
• Live validation under the rename row for empty names, collisions, and stray whitespace
• Trailing / on a new name creates a folder; foo/bar.md creates missing parents
• Sort directories first, files first, or mixed; names use natural order (file2 before file10)
• Hide gitignored files; optional git status letters (M / A / D / U / !) and bold folders
• Auto-reveal the active editor file
• Horizontal scroll for long names (clip remains the fallback)
• Disable Drag and Drop in the tree without losing drag onto the canvas

Changed

• New File / New Folder start empty; empty Enter cancels
• Paste onto a name collision opens rename with copy selected
• Undo of New File / Duplicate / Paste moves the new path to Trash so Redo can restore it
• Multi-select move, trash, and paste undo as one step
• Trash lists the files and warns if one is open in the editor
• Cut rows stay dimmed until paste or Escape
• ⌘Enter / double-click opens permanently; click / Space still previews

Fixed

• Inline rename accepts typed letters; F2 selects the stem, not the extension
• Escape cancels rename and returns focus to the tree
• First click of a newly selected row no longer starts rename; slow-click still does
• Click empty space in the file tree to deselect rows

Performance

• Source Control and Media Library switch immediately; git status, history, and file-tree git paint run in the background with a loading state instead of freezing clicks
• The Media Library only reads expanded folders, so large image/ / video/ libraries no longer stall expand, search, or panel toggles
• Preference writes (layout, expand, inspector) coalesce on a background thread so sidebar clicks do not wait on prefs.json

v1.5.7

Added

• Voice Isolator
• Voice Changer
• Forced Alignment
• Sound Effects

Changed

• Clips on a track can now be targeted the same way from typed prompts, @ mentions, and realtime voice — by name, filename, or short id, not only UUID.

Fixed

• Export state
• Backspace in the agent chat field was aborting on macOS’s IME path

v1.5.6

Added Knox Audio Endpoints

• Music
• TTS
• STT

Fixed

• Agent audio-card Play seeks the clip on the timeline and uses KnoxStudio playback (same as video cards), instead of opening the MP3 in the system player
• Asking the Manager to add captions/subtitles or transcribe an existing video now goes to the Editor STT path (caption_clip) instead of generate_video

Changed

• Caption cues use larger bold type on a compact bottom-center pill (shrink-wrapped to the words) instead of a full-width bar with small text

v1.5.5

• Screen capture improvements
• Video player optimizations

v1.5.4

• Git Improvements
• File Tree Improvements

v1.5.3

Added

• Elapsed-duration kit component: hours, minutes, and seconds broken out of a Duration, with an optional tenths-of-a-second precision mode for live timers, localized unit labels, and an optional clock icon. Generation cards and the Director pipeline now use it instead of their own 1:02 / 12.3s strings
• Generation cards persist and display their permanent output path; the card’s copy dump and the Markdown/plain-text conversation export include elapsed and path
• Show in Finder on a generation card whose file is no longer at the saved location, plus a "Missing" card state with the last saved path
• Generation-history lookup by prompt and source_path on stored assets, so a restored card can find the real file or the retained source

Changed

• Production KnoxStudio API origin is now https://api.knoxstudio.ai (was api.knox.chat) across Manager, Editor, Image, Vision, Video, and Voice models, OAuth authorize / token / userinfo / mint / revoke, the LLM client, the realtime WebSocket origin, and continuity vision. Existing configs with a stale api.knox.chat endpoint are rewritten on load
• AI Agent Configuration opens on the Defaults tab, which is now the first sidebar item
• Canvas quick view follows the active dark/light UI theme instead of always painting a cinema-black backdrop and plate
• Media Library file tree no longer draws a folder icon per row — only file-type glyphs remain
• Removed the vendored egui/ tree

Fixed

• Opening a past thread no longer restores video cards as live Pending jobs; restored cards are settled against generation history
• History restore keeps the real generation time — from history timestamps or the stored file’s mtime — and the stored file location, instead of resetting the card to 0.0 s and losing where the output went
• Generation cards now persist as soon as a job completes or fails, so restoring history shows the finished state rather than a frozen in-flight timer

v1.5.2

GPUI now matches the remaining egui editor, inspector, agent, and screenplay surfaces that were still thinner after the 1.5.0 runtime switch.

Cmd/Shift clip selection no longer depends on finding a sliver of empty track: a modifier-click hits the clip body even when trim handles eat the whole block.

Timeline

• Cmd-click toggles and Shift-click range-selects clips and gaps without hunting for a tiny hand-cursor gap; trim handles yield to selection while a modifier is held
• Scrollbar thumbs are draggable; clicking the track jumps scroll
• Gap menu: named marker header, Red / Green / Blue / Yellow / Orange, and Delete Marker “name”
• Auto Caption is disabled while a caption job is already running
• Clip hover tooltip shows Start / Duration / End (MM:SS.ms), follows the pointer, and hides during trim or slip
• Closed-hand cursor while dragging a clip or keyframe; full-height in/out lines; header/content divider; volume and pan presets disable when already at that value
• Nested-edit window title is KnoxStudio — Parent › NestedName

Canvas

• Rotated titles, shapes, and callouts paint and hit-test around the box center
• Wrapped type matches egui: align, letter-spacing, plate, shadow, outline, typewriter reveal, highlight
• Stroke trim and arrow caps on draw-on lines; numbered-step badge sits in a filled plate
• Inline text editor uses the annotation font, size, color, and plate padding, and grows while typing
• Out-of-bounds flash is a yellow frame, not a red wash

Inspector

• Color-fill clips: picker, hex, Black / White, hint
• Audio overlaps: add / remove, duration, role, mix preview, ducking amount / attack / release
• Audio tab mute plus analyzing / unavailable waveform copy
• Reset Anchor; drag the three curve handles; effect stack drag-reorder with insert gap and ghost

Recording

• Empty-canvas and transport Record run the same preflight as egui: initializing, FFmpeg missing, and screen-capture-off opens Recording prefs instead of failing silently

Agent

• Director and Storyboard stay in the chat scroller so the thread stays visible
• Estimate card lists per-shot rows; sequence shot hover is a rich popover
• Follow-up chips only on the last completed turn
• @-mention popup sits above the composer
• Agent config opens on Manager (or the last tab)
• Voice set_ui accepts the egui aliases (true / false, en-us / zh-cn / 中文, properties / chat / none / off, razor / slip keys)
• [ / ] verbosity only while the debug console is open
• Variations grid shows a first-frame thumb for video records

Screenplay

• Outline is a scene breakdown: block previews, character-tinted dialogue, find hits
• Git diff: split / unified toggle, gutters, hunk headers
• Editor context menu: Cut / Copy / Paste / Select All and Send selection to Agent
• Minimap blocks sized by content and colored by scene status

App

• One graceful-shutdown path on Quit, window close, unsaved Discard / Save → Quit, and update-install: cancel export, stop voice / AI, finalize recording, persist layout, checkpoint media DB, clean export temps
• Session error log with copy, clear, Open Panic Log, and Open Crash Reports
• Debug console lists crash reports (copy / delete / clear), a memory / health / crash stats strip, and a launch toast for unviewed crashes
• Preferences: custom 1–120 FPS next to presets
• Shortcuts overlay: Hide, Hide Others, FPS monitor, screenplay Find / Close tab / minimap / line numbers

Voice Director chrome now tells user speech from agent speech by colour and motion, instead of painting both as the same red bars. An open-but-silent session no longer redraws the whole window at display rate.

v1.5.1

Fix the GPUI preview path that could grow resident memory into tens of gigabytes until macOS paused or killed the app.

GPUI uploads every distinct RenderImage into the Metal sprite atlas and never frees the tile unless drop_image is called. Playback, live camera, quick look, and storyboard were minting a new image every frame and dropping only the CPU buffer, so Apple Silicon unified memory kept every old frame resident (~0.5 GB/s at 1080p60, ~2 GB/s at 4K).

Recording on the GPUI runtime now matches the egui behavior: Stop returns immediately instead of freezing the window, Recording and Devices settings stick, and system audio captures real sound instead of digital silence.

Memory

• Preview, camera PiP, quick-look video, storyboard playback, and Devices camera now retire the previous atlas tile when a new frame arrives
• CPU composites, rotated clips, and blur-region mosaics reuse one tile while the playhead and pixels are unchanged, instead of uploading a new image on every paint
• Timeline GPU thumbs and stills are LRU-capped; clearing those caches actually releases Metal tiles
• Memory-pressure handlers now evict preview and timeline GPU images, not only CPU thumbnail / waveform caches

Timeline editing

• Delete and Backspace both remove the current selection (clips, gaps, or keyframes); Shift+Backspace ripples the selection and Cmd+Backspace ripples the in/out range, matching the existing Shift+Delete / Cmd+Delete bindings
• Clicking a clip or gap on the timeline now steals keyboard focus, so Backspace / Delete reach clip and gap editing instead of a text field that happened to hold focus
• The timeline keeps a Workspace Playback Timeline key context, so NLE shortcuts keep firing after a clip or gap click
• Delete, ripple-delete, and ripple-delete-in/out are ignored while an annotation text label is being edited, so Backspace edits text instead of deleting the clip

Runtime

• Export progress no longer calls notify from inside render, which was spinning a full-app redraw for the entire export
• Waiting for a first decoded frame times out after five seconds, so a stalled or missing decoder cannot pin the animation loop at display rate

Recording

Stop recording no longer freezes the window. Native ScreenCaptureKit / AVFoundation teardown and ffprobe probes run on a worker; the record button becomes a disabled spinner until the take is imported, so repeated clicks cannot start a second take on top of one that is still finalizing.

• Recording and Devices preferences now stick: AppSession.capture is the single source of truth, so the 250ms poll no longer overwrites Recording-tab toggles with the manager's stale copy
• System audio is independent of screen capture, so an audio-only take is valid and is imported instead of being silently deleted
• ScreenCaptureKit no longer excludes KnoxStudio's own output, which was recording digital silence when previewing timeline media or capturing a walkthrough of the app
• A silent system-audio capture is reported in the UI instead of adding a dead track that looks like a success
• Native start no longer reports success when the ScreenCaptureKit semaphore times out
• Camera permission no longer deadlocks the main thread waiting on the system prompt
• Quitting mid-take finalizes the recording so the .mov is playable
• Import uses durations and resolution already probed on the finalize worker, so ffprobe never runs on the UI thread

v1.5.0

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.
