Workflow
Podcast / long video → Highlight clip
Short answer
Take a podcast / long video to a highlight clip. 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.
Get a clean transcript
Auto-generated with timestamps. Removes filler before highlight detection.
Detect highlight moments
Pick 6-10 hook-dense windows: topic intro, story arc midpoint, surprise / twist, callback.
Burn per-platform captions
TikTok-classic, Reels-modern, Shorts-bold. Word-by-word timing, not paragraph dumps.
Export with the Instagram Reels preset
Per-platform bitrate, codec, and safe-zone. The platform constraint registry is the source of truth.
What you end up with
- Highlight clips
Limits to know
- 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.
