# TalkEdit — UI Polish Plan

## 1. Tooltips: show what it does + keyboard shortcut

Every toolbar button and action button should have a `title` that explains the action and shows the keyboard shortcut if one exists.

### Toolbar buttons (App.tsx)

Current: `title={label}` → shows just the name.
New format: `title="Cut the selected or marked range  [Ctrl+X]"`

| Button | Current tooltip | New tooltip |
|--------|----------------|-------------|
| Cut | "Cut" | "Cut selected word range or mark in/out area  [Ctrl+X]" |
| Mute | "Mute" | "Mute selected word range or mark in/out area  [Ctrl+M]" |
| Gain Zone | "Gain Zone" | "Add gain zone from selection or mark in/out  [Ctrl+G]" |
| Speed Zone | "Speed Zone" | "Add speed zone from selection or mark in/out  [Ctrl+Shift+S]" |
| Zones | "Zones" | "Open zone editor panel  [Ctrl+Shift+Z]" |
| Pause Trim | "Pause Trim" | "Detect and remove silent pauses  [Ctrl+T]" |
| Markers | "Markers" | "Add and manage timeline markers  [Ctrl+Shift+M]" |
| Music | "Music" | "Add background music track  [Ctrl+Shift+B]" |
| Append | "Append" | "Append additional video clips  [Ctrl+Shift+A]" |
| Reprocess | "Reprocess transcript with selected model" | "Re-transcribe entire video with selected model |
| AI | "AI" | "AI filler detection and clip suggestions  [Ctrl+I]" |
| Export | "Export" | "Export video with current edits  [Ctrl+E]" |
| Settings | "Settings" | "Configure AI providers, shortcuts, models  [Ctrl+,]" |

### File menu dropdown items

| Item | Current | New |
|------|---------|-----|
| New Project | none | "Start a new empty project" |
| Open File | none | "Open a video or audio file for transcription" |
| Load Project | none | "Open a saved .aive project file" |
| Save | none | "Save current project  [Ctrl+S]" |
| Save As | none | "Save a copy of the current project" |

### Waveform timeline controls

| Element | New tooltip |
|---------|-------------|
| Show adjusted timeline checkbox | "Compress cut regions to see the output timeline without gaps" |
| Cut zones toggle | "Show/hide cut ranges on the timeline" |
| Mute zones toggle | "Show/hide mute ranges on the timeline" |
| Gain zones toggle | "Show/hide gain ranges on the timeline" |
| Speed zones toggle | "Show/hide speed ranges on the timeline" |
| Zoom instruction text | "Scroll to pan · Ctrl+Scroll to zoom  [Ctrl+= to reset zoom]" |
| Thumbnail toggle | "Show waveform thumbnail previews from the video" |

### Transcript selection toolbar

| Button | New tooltip |
|--------|-------------|
| Cut | "Remove this word range from the output" |
| Mute | "Silence audio for this word range" |
| Gain | "Adjust volume for this word range — positive boosts, negative reduces" |
| Speed | "Change playback speed for this word range — lower is slower, higher is faster" |
| Re-transcribe | "Re-run Whisper transcription on just this segment to improve accuracy" |

### AIPanel buttons

| Button | New tooltip |
|--------|-------------|
| Detect Filler Words | "Scan the entire transcript for filler words (um, uh, like, you know…) and mark for removal" |
| Apply All | "Create cut ranges for all detected filler words at once" |
| Dismiss | "Clear detected filler word results without applying" |
| Find Best Clips | "Analyze transcript to find the most engaging 20-60 second segments for social media" |
| Preview clip | "Seek to this clip's position and play a preview" |
| Export clip | "Export just this segment as a standalone video file" |

### ExportDialog controls

Every control needs a tooltip — this is the most complex panel with zero tooltips.

| Control | Tooltip |
|---------|---------|
| Fast export card | "Stream copy — no re-encoding, fast but no effects or cuts applied" |
| Re-encode card | "Full re-encode — applies cuts, gain, speed, zoom, captions, and effects" |
| Resolution select | "Output video resolution — higher = larger file" |
| Format select | "Output container format — MP4 is most compatible" |
| Enable zoom checkbox | "Crop and reposition the video frame — useful for removing black bars or reframing" |
| Zoom slider | "Magnification level — 1.0x is original, higher values zoom in" |
| Pan X slider | "Horizontal position of the crop window — negative moves left, positive moves right" |
| Pan Y slider | "Vertical position of the crop window — negative moves up, positive moves down" |
| Background removal checkbox | "Remove or replace the background behind the speaker" |
| Background blur slider | "Amount of Gaussian blur applied to the background" |
| Loudness normalization checkbox | "Normalize audio to a consistent loudness target — recommended for YouTube" |
| LUFS target select | "Loudness target: YouTube (-14), Spotify (-16), Broadcast (-23)" |
| Audio enhancement checkbox | "Apply noise reduction and speech enhancement (DeepFilterNet)" |
| Captions select | "Burn captions into video, export as separate file (SRT/VTT), or none" |
| Export Transcript section | "Export just the transcript text or subtitles without the video" |

### SettingsPanel controls

| Control | Tooltip |
|---------|---------|
| Zone preview padding | "Extra context time shown before and after each zone when previewing" |
| Confidence threshold | "Words below this confidence get an orange underline — lower = show fewer warnings" |
| AI provider selector | "Choose which AI backend powers filler detection, chapters, and suggestions" |
| Ollama base URL | "URL of your Ollama instance — default is localhost:11434" |
| Ollama model | "Model name to use for AI features — requires Ollama running with this model pulled" |
| OpenAI API key | "Your OpenAI API key — stored encrypted on your machine" |
| Claude API key | "Your Anthropic Claude API key — stored encrypted on your machine" |
| Keyboard shortcut inputs | "Click then press the key combination you want to assign" |

### Zone detail tooltips

| Element | Tooltip |
|---------|---------|
| Zone preview button | "Preview this zone with {N}s of context before and after" |
| Gain dB input | "Volume adjustment in decibels — +6 dB doubles volume, -6 dB halves it" |

## 2. Help menu / feature documentation

### 2.1 Help button in toolbar

Add a `?` help button to the right side of the toolbar (next to Settings):

```
[? Help]
```

Clicking it opens a **Help panel** (not a dialog — uses the existing sidebar panel system, or slides in as an overlay).

### 2.2 Help panel sections

#### Getting Started (for first-time users)

```
Welcome to TalkEdit

1. Open a video file → click "Open Video File" or press Ctrl+O
2. Wait for transcription — Whisper processes your audio and creates a word-level transcript
3. Edit by selecting words → choose Cut, Mute, Gain, or Speed from the toolbar
4. Use AI tools → detect filler words, find clips, auto-chapter
5. Export → apply all edits and save your final video

Pro tip: press ? anytime to see all keyboard shortcuts
```

#### Feature reference

**Transcription**
- Select a Whisper model from the toolbar dropdown (larger = more accurate but slower)
- Click a word to select it, Shift+click to extend the selection
- Ctrl+click any word to seek the video to that timestamp
- Double-click any word to edit its text
- Right-click or use the selection toolbar to apply Cut/Mute/Gain/Speed
- Select a word range and click Re-transcribe to improve accuracy on that segment

**Zones (Cut / Mute / Gain / Speed)**
- Zones are time-range edits applied during export
- Create zones by: selecting words in the transcript, using mark-in/mark-out on the timeline, or dragging on the waveform while in zone mode
- Cut = removes the segment from output entirely
- Mute = silences audio but keeps the video
- Gain = adjust volume (positive = louder, negative = quieter)
- Speed = change playback speed
- All zones can be resized and moved on the waveform timeline
- View and manage all zones in the Zone Editor panel

**Waveform Timeline**
- The waveform shows your audio with all zone overlays
- Click to seek, drag to scrub
- Enter Cut/Mute/Gain/Speed mode from the toolbar, then drag on the waveform to create a zone
- Click an existing zone to select it — drag edges to resize, drag body to move
- Press Delete or Backspace to remove the selected zone
- Ctrl+Scroll to zoom in/out, Scroll to pan horizontally
- Toggle individual zone types on/off with the colored buttons
- "Show adjusted timeline" compresses cut regions to preview the output

**AI Features**
- Filler word detection: finds "um", "uh", "like", "you know" and similar words. Add custom fillers in the AI panel. Apply All to create cut ranges for all detected fillers at once.
- Clip suggestions: analyzes your transcript to find the best 20-60 second segments for TikTok, YouTube Shorts, or Instagram Reels.
- AI features work locally with the bundled Qwen3 model (no internet needed) or via Ollama/OpenAI/Claude — configure in Settings.

**Markers**
- Markers are named timestamps pinned to the waveform
- Add markers at the current playhead position with a label and color
- Markers auto-sort as chapters — copy as YouTube timestamps format
- Useful for chapter breaks, key moments, or section headings

**Music & Append**
- Background Music: add a music track with auto-ducking (music lowers when someone speaks)
- Append Clips: load additional video files to concatenate during export
- Both are applied during re-encode export only

**Export**
- Fast mode (stream copy): no quality loss, but doesn't apply cuts, effects, or music — only works if you haven't made any edits
- Re-encode mode: applies all edits, cuts, effects, captions, and music
- Captions: burn directly into video or export as separate SRT/VTT file
- Loudness normalization: match YouTube (-14 LUFS), Spotify (-16), or Broadcast (-23) standards
- Audio enhancement: noise reduction and speech clarity via DeepFilterNet
- Video zoom: crop and reposition the frame (useful for removing letterboxing or reframing)

**Keyboard Shortcuts**
[Full table of all shortcuts — same as the ? cheatsheet but always visible in this section]

**Settings**
- AI Providers: configure Ollama (local), OpenAI (cloud), or Claude (cloud). The bundled Qwen3 model works with zero setup.
- Model Management: view and delete downloaded Whisper and LLM models to free disk space
- Keyboard Shortcuts: remap any shortcut — click a binding then press your desired combination
- Confidence threshold: adjust the low-confidence word highlighting sensitivity
- Zone preview padding: how much context to show before/after zones during preview

### 2.3 First-run onboarding

When a user opens the app for the first time (no license activated, no project loaded):

Show a **welcome overlay** with:
1. "Welcome to TalkEdit" heading
2. Brief description: "The offline video editor for long-form content"
3. Three quick-start steps with icons:
   - Open a video → starts transcription
   - Edit by deleting words → cuts out the matching video
   - Export your final cut
4. "Got it" button that dismisses permanently (store in localStorage)
5. A "Show this again" checkbox in the Help panel

## 3. Keyboard shortcut cheatsheet improvements

Current: `?` key appends a `<div>` to `document.body` with a table of shortcuts.

### Fixes:
- [ ] Render the cheatsheet as a React portal (inside a modal overlay) instead of manual DOM
- [ ] Add a close button (×) in the top-right corner
- [ ] Group shortcuts by category with visual headers (Transport, Editing, File, View)
- [ ] Show the current active preset name at the top
- [ ] Add the `?` tooltip "Show/hide keyboard shortcuts" to itself
- [ ] Show the cheatsheet from the Help panel too (not just `?` key)

### Categories and grouping:

| Transport | Edit | File | View |
|-----------|------|------|------|
| Space — Play/Pause | Delete — Cut selection | Ctrl+S — Save | ? — Toggle cheatsheet |
| ← → — Skip 5s | I — Mark in | Ctrl+O — Open | Ctrl+F — Find |
| J — Slow down | O — Mark out | Ctrl+E — Export | |
| K — Pause | Ctrl+Z — Undo | | |
| L — Speed up | Ctrl+Shift+Z — Redo | | |

## 4. Missing states (empty/loading/error)

### Empty states

| Component | Current | Fix |
|-----------|---------|-----|
| MarkersPanel | Shows nothing when no markers | Add: "No markers yet. Press M or click Add Marker to create one." |
| AIPanel (clips) | Shows nothing before first detection | Add: "Click 'Find Best Clips' to discover the most shareable moments in your video." |
| AppendClipPanel | "No additional clips loaded" | Keep but add hint: "Add video files to concatenate during export." |
| WaveformTimeline (zones) | Canvas is empty | No change needed — zones are overlays, not content |

### Error states

| Component | Current | Fix |
|-----------|---------|-----|
| AIPanel | Errors logged to console only | Show error message in the panel with a retry button |
| ExportDialog | Shows export error in a red box | Keep, but add a "Copy error" button |
| VideoPlayer | No error for broken video | Add an error state with "Could not load video" + re-select button |
| WaveformTimeline | Shows error text in a `<pre>` tag | Keep, but add a "Retry" button |
| Silence detection | Errors use `alert()` | Show error inline in the panel |

### Loading states

| Component | Current | Fix |
|-----------|---------|-----|
| WaveformTimeline | Blank canvas while audio loads | Add a centered "Loading waveform…" spinner |
| Export | Percentage text only | Add a determinate progress bar |
| Transcription | Spinning waveform bars + text | Add a determinate progress bar for model download phase |
| AI features | Spinner + "Processing…" | Add descriptive step text ("Analyzing transcript…") |

## 5. Consistency fixes

### 5.1 Fix mute zone color in ZoneEditor
`ZoneEditor.tsx` uses `border-orange-500/40` for mute zones — should be `border-blue-500/40` to match the waveform timeline's blue mute color.

### 5.2 Unify disabled opacity
- All disabled buttons: `opacity-40` (currently some use 50%)

### 5.3 Unify border radius
- All toolbar buttons: `rounded-md` (keep)
- All sidebar panel inputs: `rounded-lg` (keep)
- All zone/detection list items: `rounded-lg` (currently `rounded`)

### 5.4 Remove orphaned VolumePanel
`VolumePanel.tsx` is not imported anywhere. Either wire it into the sidebar or remove it.
