# TalkEdit — Feature Roadmap

Features are grouped by priority. Check off items as they are implemented.

## 🔴 Highest Impact Next — Conversion and retention

- [x] [#015] **Word text correction** — double-click any word to edit its text in-place. Preserves timing and confidence. Pure frontend state change. (2026-05-04)

- [x] [#013] **Re-transcribe selection** — select any word range in the transcript and click "Re-transcribe" to re-run Whisper on just that segment. Backend extracts audio via FFmpeg, transcribes with offset-adjusted timestamps. (2026-05-04)

- [x] [#012] **Low-confidence word highlighting** — words with `confidence < 0.6` (configurable in Settings) get an orange dotted underline. Hover shows exact confidence %. (2026-05-04)

- [x] [#018] **Audio normalization / loudness targeting** — Integrated checkbox in Export panel with LUFS target selector (-14 YouTube, -16 Spotify, -23 Broadcast). Applied during export via FFmpeg `loudnorm` in the audio filter chain. No intermediate files. (2026-05-04)

- [x] [#024] **Export to transcript text / SRT only** — "Export Transcript Only" section in Export panel with format selector (plain text or SRT). Uses `POST /export/transcript` backend endpoint. Respects word cuts. (2026-05-04)

- [x] [#023] **Batch silence removal** — full-file scan + remove all pauses above threshold in one click. Implemented by `SilenceTrimmerPanel` + `POST /audio/detect-silence` (FFmpeg silencedetect).

## 🟡 Medium Impact — Workflow completeness

- [ ] [#016] **Named timeline markers** — drop named marker pins on the waveform (like Resolve markers). Store as `{ id, time, label, color }` in the project. Rendered as colored triangles on the timeline canvas.

- [ ] [#017] **Chapters** — group markers into named chapter ranges. Useful for podcasts and lectures. Exportable as YouTube chapter timestamps in the description.

- [ ] [#041] **Customizable hotkeys / keymap editor (left-hand focused)** — allow users to view, remap, and reset keyboard shortcuts (transport, edit, save/export, zone tools), with a default preset optimized for left-hand reach (Q/W/E/R/A/S/D/F/Z/X/C/V + modifiers). Include conflict detection, an alternate standard preset, and one-click "restore defaults".

- [ ] [#022] **Clip thumbnail strip** — video frame thumbnails along the timeline so users can navigate visually, not only by waveform. Backend: `ffmpeg` thumbnail extraction at regular intervals.

---

## 🟢 Lower Impact — Expansion and advanced scope

- [ ] [#020] **Video zoom / punch-in** — scale and position the video (crop, zoom, pan). Used constantly on talking-head videos for emphasis. Backend: `ffmpeg -vf crop/scale/zoompan`.

- [ ] [#021] **Multi-clip / append** — load a second video and append it to the timeline. Even without a full multi-track timeline, "append clip" is a heavily used workflow.

- [ ] [#019] **Background music track** — a second audio track for background music with volume ducking. Major gap in Descript that TalkEdit could own. Backend: `ffmpeg` amix + `asendcmd` for auto-ducking.

- [ ] [#014] **Optional VibeVoice-ASR-HF transcription backend (future)** — evaluate as an alternate transcription mode for long-form, speaker-attributed transcripts. Keep WhisperX as the default for word-level timestamp editing.

## 💡 TalkEdit competitive advantages to lean into

These aren't features to build — they're things to make more visible in the UI and README:

- **100% offline / no account required** — CapCut requires login and sends data to servers. Descript is cloud-first. TalkEdit never leaves the machine.
- **Local AI models** — Ollama support means no API costs and no data leaving the device.
- **Word-level precision** — editing by deleting words (not dragging razor cuts) is faster for talking-head content than any timeline-based editor.
- **Works on long files** — virtualized transcript + chunked waveform handles 1hr+ content that bogs down CapCut.
