How this service works
Veo 3.1 Fast - text-to-video (async, dynamic pricing)
Output
Returns a request_id immediately upon submission. The agent must poll the fal.ai queue status endpoint using that request_id to retrieve the final video URL and generation metadata once processing completes. The video is generated by Google's Veo 3.1 Fast model optimized for speed.
Example use cases
Social media reel from product description
“Create a 5-second video clip of a sleek black espresso machine on a marble countertop with steam rising from the cup — I want it cinematic and modern, for an Instagram ad.”
Animated explainer scene for a presentation
“Generate a video showing a futuristic city skyline at dusk with flying cars and neon lights, like a sci-fi movie establishing shot — I'll use it as a background clip in my pitch deck.”
Nature b-roll for a documentary edit
“Make me an AI video of ocean waves crashing against rocky cliffs at sunset, slow motion feel, wide angle — I need it as b-roll footage for a nature documentary.”
Technical details
Endpoint
POSThttps://fal-queue.mpp.tempo.xyz/fal-ai/veo3.1/fast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to generate video from text using Google's Veo 3.1 Fast model and can tolerate async processing (video generation typically exceeds synchronous timeout limits). Prefer this over synchronous alternatives when video quality from Veo 3.1 is specifically required, or when the generation is expected to take more than 100 seconds. The fast variant prioritizes speed over maximum quality within the Veo 3.1 model family.
Side effects
- Invalid or empty text prompt returns a 400 validation error
- Dynamic pricing may cause payment or budget failures if USDC balance is insufficient
- Generation job may time out or fail on the queue side, returning an error status on polling
- Prompt policy violations (unsafe content) may result in rejection
- Result polling may return pending status for extended periods during high queue load
