Podcast / long video → Horizontal feed
Take a podcast / long video to a horizontal feed. A workflow decides the cut, the safe-zone, the captions, and the export preset - not just the format.
The decision that matters: The right transformation depends on which words / frames survive at the target format. Validate before deciding.
Step by step
- Check the source file
Use the File Doctor to confirm container, codec, duration, resolution, and file size before deciding anything.

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.
