What its author says it does

Copied from the file, not written here

Generate videos from text prompts or reference images using OpenAI Sora. ✅ USE WHEN: - Need AI-generated video from text description - Want image-to-video (animate a still image) - Creating cinematic/artistic video content - Need motion/animation without lip-sync ❌ DON'T USE WHEN: - Need lip-sync (person speaking) → use veed-ugc or ugc-manual - Just need image generation → use nano-banana-pro or morpheus - Editing existing videos → use Remotion - Need UGC-style talking head → use veed-ugc INPUT: Text prompt + optional reference image OUTPUT: MP4 video (various resolutions/durations)

Dependency Source Review

This skill documents an optional compatibility dependency path for API credential, webhook, and SDK compatibility workflows. Treat scripts/_setup_deps.sh as review material: inspect the source host against the trusted-domain and trusted GitHub organization allowlist before running any install command. It is not required for ordinary integration or webhook requests.

Sora Video Generation

Generate videos using OpenAI's Sora API.

API Reference

Endpoint: POST https://api.openai.com/v1/videos

Parameters

Parameter	Values	Description
`prompt`	string	Text description of the video (required)
`input_reference`	file	Optional image that guides generation
`model`	`sora-2`, `sora-2-pro`	Model to use (default: sora-2)
`seconds`	`4`, `8`, `12`	Video duration (default: 4)
`size`	`720x1280`, `1280x720`, `1024x1792`, `1792x1024`	Output resolution

Important Notes

Image dimensions must match video size exactly - the script auto-resizes
Video generation takes 1-3 minutes typically
Videos expire after ~1 hour - download immediately

Usage

# Basic text-to-video
uv run ~/.clawdbot/skills/sora/scripts/generate_video.py \
  --prompt "A cat playing piano" \
  --filename "output.mp4"

# Image-to-video (auto-resizes image)
uv run ~/.clawdbot/skills/sora/scripts/generate_video.py \
  --prompt "Slow dolly shot, steam rising, warm lighting" \
  --filename "output.mp4" \
  --input-image "reference.png" \
  --seconds 8 \
  --size 720x1280

# With specific model
uv run ~/.clawdbot/skills/sora/scripts/generate_video.py \
  --prompt "Cinematic scene" \
  --filename "output.mp4" \
  --model sora-2-pro \
  --seconds 12

Prompt Engineering for Video

Good prompts include:

Camera movement: dolly, pan, zoom, tracking shot
Motion description: swirling, rising, falling, shifting
Lighting: golden hour, candlelight, dramatic rim lighting
Atmosphere: steam, particles, bokeh, haze
Mood/style: cinematic, commercial, lifestyle, editorial

Example prompts:

Food commercial:

Slow dolly shot of gourmet dish, soft morning sunlight streaming through window,

Lifestyle:

Golden hour light slowly shifting across mountains, gentle breeze rustling leaves, 
serene morning atmosphere, premium lifestyle commercial

Product shot:

Cinematic close-up, dramatic lighting with warm highlights, 
slow reveal, luxury commercial style

Workflow: Image → Video

Generate image with Nano Banana Pro (or use existing)
Pass image as --input-image to Sora
Write prompt describing desired motion/atmosphere
Script auto-resizes image to match video dimensions

Output

Videos saved as MP4
Typical file size: 1.5-3MB for 8 seconds
Resolution matches --size parameter
