A reproducible workflow for planning a shot, generating a reference frame, testing image-to-video motion, and finishing the edit.

Step-by-Step Instructions

1

Build a reference frame before generating motion

Write a shot brief before opening the image model. Define the subject, location, lens feel, lighting direction, camera height, framing, and delivery aspect ratio. Generate several stills and keep the strongest frame as the visual reference.

Choose an image-to-video mode and test a short clip

Open the provider's current image-to-video workflow and upload the selected still as the first frame. Start with a short duration and a single camera move. Model names, supported durations, and export limits vary by plan, so confirm the options shown in your account.

Control movement without changing the whole scene

Use available motion controls, masks, or region brushes to separate moving elements from the background. Keep the first pass subtle, inspect faces and edges frame by frame, and reduce motion strength if objects distort or the camera move changes the composition.

Finish sound, pacing, and export quality

Cut the best generation into the edit, then add ambience, effects, and voiceover as separate layers. Check the output resolution, frame rate, watermark, and commercial-use terms on the plan you used before delivering client or monetized work.

Recommended Prompt Template
"Deep reflective cinematic narration: "The rain washed away the traces, but the neon glow remembered every secret.""
