Turn livestream VOD moments into shortform clips — facecam-stacked verticals in 1080p or 4K, auto-captions, ASS/SRT export. A six-hour stream becomes a tray of ready-to-post shorts.

---

What it does

• Create multi-clip VOD projects for stream sessions.
• Pull recent Twitch VODs, Twitch markers, and Twitch clips via shared auth.deutschmark.online Twitch login.
• Import manual timestamps from any hotkey or marker workflow.
• Surface all those moments in a Session Inbox.
• Prep moments as shorts with streamer-specific presets:
  • Gameplay Focus
  • Facecam Top — real stacked composition: your facecam (guide-drawn, rounded corners) over the game on a blurred backdrop, captions burned into the dark zone. 1080x1920 and 4K 2160x3840.
  • Baked Text Punch
• Create Clip from Moment — mark a range, click once: the clip is cut, the vertical facecam layout switches on, and you're walked to captions.
• Batch-prep a whole inbox and batch-queue prepared shorts for longform.
• Stitch clips into a preview sequence, transcribe captions, and export.
• Build a horizontal longform derivative from queued prepared shorts.
• Draw a facecam guide once over a grabbed frame — remembered every session for recurring stream layouts, with a live preview of the vertical composition.

Captions

• 1-click caption engine download (whisper.cpp, ~75 MB) — no Python, no pip, no terminal.
• Optional speaker separation (sherpa-onnx, ~50 MB), same one-click model.
• Editable captions with speaker colors, ASS/SRT export, and burn-in control.
