Screen recording → Vertical feed (4:5)
Take a screen recording to a vertical feed (4:5). A workflow decides the cut, the safe-zone, the captions, and the export preset - not just the format.
The decision that matters: Legibility, not framing. A 2560×1440 recording scaled into 1080 width shrinks body text to ~42%. Crop to the active window instead of scaling the whole desktop.
Step by step
- Check the source file
Use the File Doctor to confirm container, codec, duration, resolution, and file size before deciding anything.
File Doctorproduct-backed - Identify the active region
Wide screen recordings shrink to unreadable when scaled into a vertical frame. Crop to the active window instead of scaling the whole desktop.
Crop calculatorproduct-backed - Reframe to the target vertical aspect
Centre-cover-crop (lose sides) or letterbox (keep everything, add bars). Pick by what survives at the target resolution.
Aspect previewproduct-backed - Apply the platform safe-zone
Subject + CTA inside the safe band; text/face outside the overlay.
product-backed - Export at the tiktok preset
Per-platform bitrate, codec, and safe-zone. The platform constraint registry is the source of truth.

What this path cannot do
- Workflow outputs depend on the source - a 60-minute podcast produces ~10 vertical clips, not 60.
- Per-platform captions and safe-zones are platform-specific, not generic.
