## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sift-web-tools-video-storyboard-generator-4dae9674
```

Example prompt: Generate a storyboard sprite sheet for the video at https://example.com/myvideo.mp4, using the web_player preset with tiles every 10 seconds and a tile width of 160 pixels.

## When to prefer this

Choose this endpoint when you need to add scrub-bar thumbnail previews to a web video player, produce a visual contact sheet for editorial review, or generate a WebVTT thumbnail track for any hosted video file. Ideal for agent workflows that process video content at a URL without needing a full video editing pipeline.

## Known failure modes

- Invalid or inaccessible video URL returns an error
- Video format not supported results in processing failure
- Interval value outside 0.5-600 range causes a validation error
- Width outside 64-480 range causes a validation error
- Payment not processed means no charge and no result (only charged on HTTP 200)
- Very large or long video files may time out

## How this service works

Video scrub-bar storyboard: sprite sheets plus WebVTT thumbnail track (zip). Hover-preview thumbnails for a video player: sprite sheets capped at the device texture limit plus a WebVTT track whose cues use each frame's real timestamp, so they never drift. Handles phone rotation. Presets web_player, web_player_hd, mobile (WebP, 2048 cap), editor_filmstrip, contact_sheet.

## Output

Returns a sprite sheet image (PNG grid of video frame thumbnails) and a WebVTT file that maps timecodes to tile coordinates, ready to plug into a video player's thumbnail preview track.
