Multi-Format Cuts
Recompose one build for YouTube, LinkedIn, Reels, and more.
One Build, Several Platforms
fluos compositions are HTML + motion, not a fixed camera crop. After you lock a cut in one aspect ratio, you can ask for another format in the same chat — the agent recomposes layout, type scale, and safe areas for the new frame instead of starting from a blank project.
Typical path:
- Ship a 16:9 master (YouTube, site, decks)
- Ask for a 9:16 cut (TikTok / Reels / Shorts)
- Optionally ask for 1:1 (feed / X / LinkedIn square)
How to Ask
Be explicit about ratio and platform. Keep brand and story locked; only change the frame.
Recompose this for 9:16 Reels.
Keep the same story beats, logo, and palette.
Rework layout and type for vertical safe areas — don't rebuild from scratch.Give me a 1:1 cut for LinkedIn feed from this 16:9.
Same VO and end card; tighten framing for square.What Changes vs What Stays
| Usually preserved | Usually adapted |
|---|---|
| Story beats / narration intent | Stage size and safe insets |
| Brand colors, logo, type voice | Layout, hierarchy, line breaks |
| Motion language / pacing feel | Cropping and element placement |
| End card message | Duration tweaks if a platform needs a shorter cut |
Export each cut separately from preview (MP4 or GIF) once that composition looks right — see Preview and Exports.
Platform Cheatsheet
| Platform | Ratio | Notes |
|---|---|---|
| YouTube, landing page | 16:9 | Default master for longer explainers |
| TikTok, Reels, Shorts | 9:16 | Prefer shorter, punchier hooks |
| LinkedIn / X feed | 1:1 or 16:9 | Square reads well in feed; 16:9 still works |
| Stories | 9:16 | Keep critical type inside safe margins |
Plan Mode Helps
In Plan, the agent is steered to lock aspect ratio / target platform and total duration before build. If you know you need multiple formats, say so up front:
We'll need 16:9 and 9:16. Design the master in 16:9 first,
then we'll cut vertical after approval.Tips
- Finish creative direction in one ratio before mass-producing variants.
- Reuse brand rules so every cut stays consistent.
- For silent loops or thumbnails, export GIF; for anything with audio, export MP4.
- Narrow follow-ups work best: one format request per message when iterating.
