veo-3.1-fast text-to-video: core parameters and use-case visual guide
Centered on veo-3.1-fast's text-to-video capability, this piece uses a short film that can be generated directly to demonstrate "how parameters shape the final video": the camera cuts between a data panel and realistic-feeling scenes, paired with native voiceover and ambient sound, to explain the input dimensions of resolution, duration, aspect ratio, audio toggle, and negative prompt. This work uses only the fields that actually exist in this model's schema: prompt, resolution, duration, aspect_ratio, generate_audio, negative_prompt, seed, with no reference image input—it is pure text-to-video. The base is fixed at resolution=1080p, duration=8, aspect_ratio=16:9, generate_audio=true, and provides a negative prompt to avoid distorted or flickering on-screen text; the positive prompt is written in via the top-level prompt. Use cases: a quick model-capability overview for developers, a reference for parameter selection, and an effects preview before producing marketing shorts, corporate demos, educational content, and social media videos. The model emphasizes fast generation speed and integrated video-audio output, making it suitable for workflows that need quick delivery with built-in voiceover/sound effects; first-hand specifications such as resolution, duration, and frame rate are subject to the official documentation.

Model Veo 3.1 Fast
Prompt
A clean, modern explainer sequence about an AI text-to-video model. Shot 1 (0-2 seconds): the camera slowly pushes in on a dark glass control panel, where five minimalist parameter knobs are labeled resolution, duration, aspect ratio, audio, and negative prompt, glowing with a soft cyan light; shallow depth of field, subtle reflections. Shot 2 (2-5 seconds): a seamless match cut into a cinematic live-action-style scene—a small product sits on a glossy studio tabletop, warm key light from the left, soft rim light, a slow lateral dolly at eye level, faint dust motes floating in the light beams, with natural ambient sound and soft footsteps on the audio track. Shot 3 (5-8 seconds): focus pulls back from the product to the control panel, the knobs return to place, the camera gently tilts up, ending on a calm static frame with soft vignetting. Unified color grading, teal-and-orange palette, 35mm lens character, shallow depth of field, stable camera movement, natural light, rich detail on hands and surfaces, documentary-style unhurried pacing, accompanied by calm voiceover narration explaining each parameter one by one.
