How to Make AI Videos: 6 Steps from Prompt to Finished Video

If you are comparing tools, verify the current official product page rather than relying on a social post or demo reel. Google Vids says users can generate video with Veo 3 from prompts inside Google Vids. Adobe also has documentation or product pages for using Google Veo, Runway Gen-4.5 and OpenAI Sora 2/Sora 2 Pro within the Firefly ecosystem.

Write the prompt like a shot brief

A useful prompt does more than name the scene. It tells the model how the scene should be filmed.

A simple formula:

Subject + action + setting + camera angle or movement + lighting + mood or style + duration or aspect ratio.

This matches the practical guidance in the cited documentation: OpenAI recommends being clear about the frame, subject, action, setting and lighting, while Adobe suggests describing the subject, action, place, mood or style when generating video.

Too vague:

• “A person walking in a rainy street.”

More useful:

• “Wide shot of a fictional character walking down a rainy city street at night, neon signs reflected on wet pavement, slow dolly-forward camera movement, cinematic lighting, moody atmosphere, natural motion, 8 seconds.”

For a product image, make the image the anchor:

• “Use this product image as the first frame. Create a slow push-in camera move, soft studio lighting, minimalist premium background, subtle surface reflections, and do not change the product shape.”

A 6-step workflow for making a publishable AI video

1. Define the job of the video

Decide what the video is supposed to do before you generate anything. Is it for a short-form social post, a product teaser, an internal training module, a presentation background or a paid ad? The answer affects the pacing, length, framing and how much post-production you will need.

2. Pick the right generation mode

Use text-to-video when you only have an idea. Use image-to-video when you need to preserve a product photo, key visual or storyboard frame. Use edit or extend if you already have a clip and the tool supports that workflow.

3. Write a detailed first prompt

Your first prompt should include the subject, action, setting, camera, lighting and mood. Think of it as a mini brief for a cinematographer, not a search query.

4. Generate a short draft first

Do not start with the longest or highest-resolution output. OpenAI’s documentation recommends using short clips and smaller sizes while iterating, because longer videos and 1080p outputs can take significantly more time.

5. Revise one thing at a time

After each draft, adjust one group of details: the camera move, the action, the lighting, the setting or the mood. If you change everything at once, you will not know what improved the result.

6. Render the final version and finish the edit

Once the scene is close, render the best version and move into post-production: voiceover, music, sound effects, captions, logo placement, title cards and cuts between clips. OpenAI’s Sora API documentation says sora-2-pro is better suited for higher-quality and 1080p output, and it describes downloading an MP4 after a video job is complete.

How to fix a prompt when the video feels wrong

AI video usually takes a few rounds. Instead of rewriting the whole prompt, diagnose the problem and make a targeted change.

• The motion looks unnatural: describe the action more specifically, such as “walks slowly while holding a coffee cup, coat moving slightly in the wind.”
• The camera is wrong: add framing and movement terms, such as “wide shot,” “close-up,” “slow push-in” or “dolly forward.”
• The lighting misses the mood: name the light source and feeling, such as “soft studio lighting,” “warm sunset light” or “neon reflections on wet pavement.”
• The product or character changes too much: if the original visual matters, use image-to-video so the image can act as a reference point.
• The scene adds unwanted details: add constraints such as “do not add new characters,” “keep the background minimal” or “keep colors consistent.”

Post-production turns an AI clip into a real video

A beautiful AI-generated clip is not automatically a finished video. The final piece usually needs the same finishing layers as any other video:

• Voiceover: narration, product copy, tutorial explanation or a short hook.
• Music and sound effects: use only audio you have the right to use. The cited OpenAI documentation notes that copyrighted characters and music may be rejected in its workflow.
• Captions: especially useful for short-form video, where many viewers watch without sound.
• Editing rhythm: trim dead moments, combine multiple shots, add titles, insert logos and place a call to action if needed.

Adobe Firefly is one example of a tool described for generating AI video from text and images, but editing remains the quality-control stage before publishing.

Check rights and platform rules before publishing

For personal experiments, this step prevents embarrassing mistakes. For brand, commercial or monetized work, it is essential.

Adobe says video generated with Firefly models is commercially safe. If you use a partner model or another tool, read the terms for that specific model or service; Adobe has separate pages for Google Veo, Runway Gen-4.5 and OpenAI Sora models in Firefly.

For OpenAI’s Sora API, the cited documentation lists notable content limits: it does not allow generation of real people, including celebrities; copyrighted characters and music may be rejected; and input images containing human faces are blocked in that workflow.

Use this minimum checklist before posting:

• Does the video include a real person, face, voice or recognizable character?
• Does it use music, sound effects, logos, artwork or characters owned by someone else?
• Does the tool or model you used allow commercial use for your planned purpose?
• Does the platform where you are posting require AI labels or have rules for synthetic media?
• Have you reviewed the final export for visual errors, distorted text, logo mistakes or sensitive details?

Prompt templates you can adapt

Text-to-video for a short social clip

• “Wide shot of a fictional character opening a small café in the morning, sunlight streaming through the glass door, slow dolly camera movement, warm film color, natural motion, 8 seconds.”

Image-to-video for a product photo

• “Use this product photo as the first frame. Add a gentle push-in camera move, soft studio lighting, dark premium background, subtle reflections, high-end commercial style, and keep the product shape unchanged.”

Background video for YouTube or a presentation

• “A minimalist desk beside a window, open laptop, small green plant, soft afternoon light, static camera with very slight movement, focused modern mood, 10 seconds.”

Edit or extend an existing clip

• “Keep the color, composition and lighting of the current clip. Extend the scene for a few more seconds with slow camera movement, no new characters and consistent lighting.”

Bottom line

Start small. Choose the right input, write the prompt like a filming brief, generate a short draft, revise one element at a time, then finish the video with editing, audio and captions. Before using the result for a brand, ad or monetized channel, check commercial rights, real-person restrictions, copyrighted characters, music rights and the policy of the tool you used.
