How to Make Videos With AI: From Script to Final Edit

01 / The story

Start with one deliverable, not an unlimited prompt

A finished video needs a purpose, an audience and a destination. Choose one message and one next step before choosing a generator. A 30-second promotion, a tutorial and a training explainer are different jobs. Generated footage can help, but some factual details are better recorded.

This is an illustrative workflow, not a project Qlauson produced or a guarantee of a professional result. The fictional business example below is invented for planning; it is not a real shop, client, location or environmental claim.

For model selection and dated prices, use our six-tool video comparison. This article focuses on production from brief to export, not another ranking.

Step 1: write and time the script

For a 30-second first draft, around 60–70 words can be a planning starting point, but reading pace, pauses and language vary. Time an actual read. Cut ideas before accelerating the voice until it becomes hard to understand.

A useful brief states the audience, single message, factual claims, destination format and call to action. Verify every claim before generating visuals. A polished video about an inaccurate price or nonexistent feature is still inaccurate.

AI can propose wording, but a person should retain responsibility for names, numbers, promises and tone. Do not ask a generator to invent a testimonial or pretend a conceptual business has real customers.

Step 2: turn the script into a storyboard

Our fictional Harbor Refill example uses six five-second beats. For a real store, replace every process, claim and URL with verified material. Five seconds per beat is a planning structure, not a requirement of every model or platform.

Step 3: prepare truthful references

Use images and footage you own or are licensed to use. Keep a small style sheet for palette, lighting, camera angle and object proportions. For a genuine product demonstration, preserve the actual product and interface instead of generating a plausible but false replacement.

If the input shows a person, check permission for the intended use and applicable privacy rules. A tool subscription does not grant rights to someone else’s likeness or a downloaded photograph. Avoid uploading confidential client assets to unapproved services.

Reference-led generation can help continuity but does not guarantee it. Inspect shape, labels, colors and physical actions across shots rather than trusting the first frame.

Step 4: generate one shot at a time

Specify subject, action, camera movement, setting and intended duration. In image-to-video, emphasize motion rather than repeatedly redescribing the image. Runway’s guide and Adobe’s image workflow describe separate input modes; the controls available depend on the selected model. [1] [2]

An illustrative brief could ask for a gentle camera push toward an owned bottle image with stable object proportions and soft studio light. It is a shot instruction, not a promised exact result. Generate a small set of alternatives and retain only those meeting your checklist.

Watch hands, reflections, labels, collisions and continuity where relevant. Use real footage if the generated action misrepresents how a product works. Keep exact logos, text and data visualizations in controlled editing rather than ask a video model to reproduce them.

Step 5: make the sound intentionally

Options include a recorded human voice, documented text-to-speech tools or native audio in a supported video mode. Google documents Veo audio with experimental qualifications; it is not a guarantee that every generated line is synchronized or usable. ElevenLabs documents voice tools and billing, but we do not quote an unverified price. [3] [4]

Record or generate narration early enough to time the edit. Check names, pronunciations, pauses and factual wording. Listen without watching the picture: does the message still make sense?

Obtain permission before voice cloning or imitation. Music, sound effects and voice have separate license terms. “AI made it” is not a legal clearance, and a commercial platform plan does not automatically cover every uploaded or external sound.

Step 6: assemble the edit

An external editor lets you trim, pace and combine generated and authentic shots, adjust sound and add exact graphics. Blackmagic documents a free DaVinci Resolve workflow for editing/finishing up to UHD 3840 × 2160 at 60 fps, with Studio offering additional features. That does not upgrade the original generator’s native quality. [5] [6]

Choose the strongest take, not the one you spent most credits making. Match cuts to narration, leave reading time for labels and remove decorative shots that obscure the message. A simpler clear edit can work better than six unrelated impressive scenes.

Watch the complete video rather than only scrub through thumbnails. A moving artifact or audio error can be invisible in a still image.

Step 7: captions, branding and export

Add readable captions, correct names and numbers, and sufficient contrast. Keep text within destination-safe areas and give it enough time. Use real authorized branding in the editor. Do not present generated captions as verified transcription without checking them.

1920 × 1080 landscape or 1080 × 1920 portrait and H.264 MP4 are common starting points where accepted. They are not universal current requirements of every platform. Check the actual destination’s dimensions, file limits, audio rules and disclosure obligations before exporting.

Export, reopen the file and review start to finish with sound. Check clipping, caption timing, compression, the final URL and the end card. Upscaling a low-resolution source is not native high-resolution generation.

What the 30-second project might cost

A low-cost route uses owned footage, recorded narration and a free editor; it still consumes time and may need paid assets. A generated-scene route adds credits and retries. A presenter route such as Synthesia has plan-specific export restrictions. [7]

For a hypothetical budget, six five-second shots with three attempted takes each means 90 seconds of generation, not 30. At a listed 12-credit-per-second mode, that is 1,080 credits. This is arithmetic under assumptions, not measured production cost; other tools and modes have different rates. [8]

Count editing, music, voice, rejected takes and factual review. No published tool price alone establishes the complete cost of a professional 30-second video.

Rights and final publication checks

Confirm commercial permission for the plan/model, rights to inputs and audio, consent for likeness/voice use and relevant disclosure rules. Generated output is not automatically copyright-protected or non-infringing. This guide is educational, not legal advice.

We use source links rather than copy vendor demonstration files or assume embed rights. Our Claude motion-graphics guide explains a different code-rendered route.

The finished result should communicate one verified message, sound clear, remain readable and accurately show anything the viewer may rely on. Human review, not the presence of AI, makes that production decision.
