Workflow
Long YouTube video → Multi-platform pack
Short answer
Take a long YouTube video to a multi-platform pack. A workflow decides the cut, the safe-zone, the captions, and the export preset - not just the format.
The decision that matters: One source → Content Pack: 4 platform exports with platform-tuned captions + safe zones. The pack is the workflow's whole value, not the source alone.
Step by step
Check the source file
Use the File Doctor to confirm container, codec, duration, resolution, and file size before deciding anything.
Export with the Instagram Reels preset
Per-platform bitrate, codec, and safe-zone. The platform constraint registry is the source of truth.
Generate Content Pack
One source, four platform exports (TikTok + Reels + Shorts + LinkedIn) with platform-tuned captions and safe-zones.
What you end up with
- Vertical short (9:16)
- Text summary / hook copy
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.
Run the whole workflow in one place
Koldflux takes one source through checking, reframing, captions and export, and gives you a pack per platform.
