Video carries most of the delivery on Meta and effectively all of it on TikTok, yet it is the format teams produce least, because a single spot costs a shoot, an editor and a week.
Xeli builds motion from what you already own. Product stills, feed copy and brand tokens become paced sequences with a hook in the first second, captions that survive muted playback, and an end card that matches your identity.

## Why video stays scarce
- Editing time scales linearly with variants, so testing six hooks means six edits.
- Vertical reformatting breaks compositions built for landscape, and text lands under the UI overlay.
- Captions are added last, if at all, which loses the majority of viewers who watch with sound off.
- The catalog long tail never gets motion at all.

## How it works
1. **Pick the source** — Product stills, existing footage, or generated scenes. Xeli assembles from whatever the SKU already has.
2. **Write the beat sheet** — Hook, problem, product, proof, offer, end card. Timings are set for the placement rather than trimmed afterwards.
3. **Animate and caption** — Motion agents handle camera moves, transitions and product reveals, with burned-in captions styled from your kit.
4. **Cut every ratio** — 9:16, 4:5, 1:1 and 16:9 are composed independently so nothing important sits under a platform overlay.
5. **Score and export** — Each cut is scored on hook strength at two seconds, then exported at platform-compliant bitrate and duration.

## What you get
- **Hook variants**: The same body can ship with several openings, which is the highest-leverage variable in short-form performance.
- **Safe-zone aware**: Captions and offers stay clear of the UI chrome on Reels, Stories and TikTok.
- **Sound optional**: Every cut reads fully muted, with audio treated as an enhancement rather than a dependency.
- **End card discipline**: Logo, offer and call to action rendered from brand tokens, consistent across every product.

## Where it stops
- Generated motion from stills suits product-led and offer-led formats. Founder pieces, testimonials and demonstration footage still need real filming.
- Licensed music is not supplied. Bring your own library or run muted with captions.
- Very short clips of complex products can under-explain. Longer beat sheets exist for considered purchases.

### Do we need existing video footage?
No. Product stills plus feed data are enough for most catalog formats, though real footage improves the result when you have it.

### What durations are produced?
Six, fifteen and thirty second cuts by default, with per-placement duration limits respected on export.

### Can we use our own music and voiceover?
Yes. Upload audio and it is mixed under the cut with captions kept in sync.
