Video is the most layered content type in Rheos. You give it a prompt; Rheos writes a script, breaks it into scenes, generates visuals, and renders a vertical short ready for Instagram Reels, TikTok or YouTube Shorts.

​
The video formula

Every video follows the same shape:
SlotWhat it isLength
HookFirst 3 seconds. The stop-the-scroll line.~3s
MeatThe body. Tutorial, testimonial, demo, story, comparison, listicle, process-reveal, problem-solution.3–20s
CTAThe closing line and on-screen prompt.~2s
Pick the meat type up front — it shapes the whole script.

​
Visual source

Like images, video scenes come from three sources:
  • Library — your own footage and photos. Best for authentic, brand-true videos.
  • AI-generated — Rheos creates each scene’s visual from a description.
  • Text-only — typography, icons and motion design with no real footage. Great when speed matters.
You can mix sources within a single video — your face for the hook, AI visuals for the meat, text-only for the CTA.

​
The video editor

After generation, the video opens in the editor with:
  • Scene strip along the bottom — every scene shown as a thumbnail.
  • Preview in the centre — play and scrub.
  • Scene panel on the right — text layer, visual, duration, voiceover script.
  • AI chat for review — ask “tighten the hook” or “make scene 3 punchier”.
Click any scene to edit it. Regenerate its visual via the Image Studio. Edit the on-screen text layer. Change its duration. Reorder by dragging.

​
Captions and text overlays

Every scene has an editable text layer — the on-screen words. Rheos picks a default style from your brand, but you can adjust font size, position and emphasis per scene.
Brand fonts in video overlays are on the roadmap. For now, choose from the built-in font set.

​
AI review pass

Open the AI chat in the editor and ask for a full review — “is the pacing right?”, “is the CTA strong enough?”, “does scene 2 land?”. Rheos can apply its own suggestions across scenes in one go.

​
Rendering

Once you’re happy, hit Render. Rheos stitches the scenes together as a 9:16 MP4. Rendering takes a minute or two — you’ll get a notification when it’s done.

​
Publishing video

Tick the platforms in the publish panel:
  • Instagram Reels
  • TikTok
  • YouTube Shorts
  • Facebook
  • LinkedIn (native video)
  • X (native video)
Rheos uploads natively to each — no link-outs.

​
Credit costs

Video generation costs more than text or images because there’s a lot more going on. Each scene’s visual is its own generation (5 or 10 credits). The script, scene breakdown and rendering are free. A typical 15-second AI-generated video runs around 50–80 credits.
