🎬 Video Gen

Generate videos from text descriptions using Google Veo 3 (REST API, async polling).

How It Works

1. Sends prompt to Veo 3 predictLongRunning endpoint
2. Polls operation status every 10s until done (up to 5 min)
3. Downloads generated MP4 from returned URI
4. Uploads to Feishu and sends as file message

Model

• Current: veo-3.0-generate-001 (Veo 3, with native audio)
• Previous: veo-2.0-generate-001 (Veo 2, no audio)
• Also available: veo-3.0-fast-generate-001 (faster, lower quality), veo-3.1-generate-preview (latest)
• Veo 3 generates 8-second videos with synchronized audio from text prompts
• durationSeconds and personGeneration params not supported in Veo 3 — fixed duration 8s
• Download URL requires API key appended and follows 302 redirect
