Your prompt

Create a 6 seconds 9:16 b-roll clip of a runner in her late twenties using a smartphone in a park path at golden hour, to illustrate the app benefit: "tracks your pace without you touching the phone". Action: she glances at her wrist, smiles, and speeds up slightly. Screen: keep the phone screen angled away from the camera or showing only soft abstract light; do not show any readable interface. Camera: tracking shot from the side, shallow depth of field, natural handheld motion. Light: low golden sunlight. Mood: energetic and satisfied. Sound: footsteps and a steady upbeat track. Constraints: no on-screen text, no app logos, no readable UI, accurate hands.

Platform notes

Google video models (Gemini Omni Flash, Veo 3.1)

Official docs read · checked 2026-10-11

Google's Gemini API docs describe Veo 3.1 as generating video with native audio, and name Gemini Omni Flash as the recommended default; check current limits for duration and resolution, which the docs page did not list.

General notes on Google video models (Gemini Omni Flash, Veo 3.1)
  • Google's Gemini API docs name Gemini Omni Flash as the recommended default and Veo 3.1 for native audio, video extension and first/last-frame control.
  • Google's detailed Veo prompt guide could not be fully read, so structure here follows general video-prompt anatomy, not Veo-specific claims.

Runway (Gen-4.5 and earlier)

Official docs only partly readable · checked 2026-10-11

Per Runway's help center (seen via search snippet), with image-to-video the image is the first frame, so describe the motion rather than the scene.

General notes on Runway (Gen-4.5 and earlier)
  • Per Runway's help center (seen via search snippet), Gen-4.5 supports text-to-video and image-to-video. With image-to-video the image is the first frame, so describe the motion instead of re-describing the image.

Kling

Not verified: third-party guidance only · checked 2026-10-11

Only third-party guidance was found for Kling: name the camera move explicitly and give the motion an end point. Treat as unverified and test.

General notes on Kling
  • Only third-party guidance was found. Reported advice: name the camera move explicitly, keep the element count modest, and give motion an end point. Model versions behave differently, so test.

Adobe Firefly Video

Official docs only partly readable · checked 2026-10-11

Adobe's help pages (seen via search snippet) say Firefly Video reads prompts literally and works best with a single subject doing a simple action.

General notes on Adobe Firefly Video
  • Adobe's help pages (seen via search snippet) say Firefly Video reads prompts literally and gives the best results with a single subject doing a simple action; first and last frames can improve coherence.

Any text-to-video or image-to-video tool

Official docs only partly readable · checked 2026-10-11

Plain scene description that any text-to-video tool can use. OpenAI shut down Sora 2 and its Videos API on 2026-09-24, so no prompt here targets Sora.

General notes on Any text-to-video or image-to-video tool
  • Written as plain scene descriptions: subject, action over time, camera, lighting, style, aspect ratio. Duration, resolution and aspect ratio are usually settings in the tool, not words in the prompt.
  • OpenAI shut down Sora 2 and its Videos API on 2026-09-24, so none of these prompts target Sora.
