How to Create Videos with AI (Beginner Guide)

Creating video used to require cameras, editing skills, and a lot of time. Today, AI tools can help with nearly every stage: writing the script, generating footage, creating voiceovers, adding subtitles, and editing. This beginner guide walks you through a complete, realistic workflow for your first AI-assisted video. It also explains which types of tools to use at each step and how to avoid common pitfalls.

The Main Types of AI Video Tools

“AI video” covers several different categories. Knowing them helps you pick the right tool:

• Text-to-video generators: Create short clips from a written prompt. Examples include OpenAI’s Sora, Google’s Veo, Runway, Kling, and Luma. Clips are usually short, often seconds rather than minutes.
• Image-to-video: Animate a still image, for example one made in Midjourney.
• AI avatar / presenter tools: Generate a talking presenter from a script (for example Synthesia or HeyGen). These are useful for training and explainer videos.
• AI voice tools: Turn text into natural-sounding narration (for example ElevenLabs).
• AI-assisted editors: Editors that remove silences, transcribe, auto-caption, and cut clips (for example CapCut, Descript, or features in mainstream editors).

Pricing, free tiers, and watermark rules vary widely and change often. Read each tool’s current plan page, and check whether free exports include a watermark.

Step 1: Decide the Video’s Purpose and Format

1. Purpose: teach, promote, entertain, or explain?
2. Platform: YouTube (16:9), Shorts, Reels, or TikTok (9:16), or a website embed.
3. Length: For a first project, aim for 30–90 seconds.
4. Style: talking avatar, stock-style b-roll with voiceover, animated, or a mix.

Step 2: Write the Script with an AI Assistant

Write a 60-second vertical video script explaining
"3 ways to keep houseplants alive while on vacation".
Audience: busy beginners. Tone: friendly, upbeat.
Format as a table with columns: Time | Voiceover | On-screen visual | Text overlay.
Start with a 3-second hook. End with a call to action.

A table that pairs each line of narration with a visual gives you a ready-made shot list. Read the script aloud and trim anything that sounds unnatural. Want better scripts? Our guide on using ChatGPT for writing applies here too.

Step 3: Create the Visuals

Option A: Generate clips from text

Write one prompt per shot. Good video prompts describe the subject, action, setting, camera, lighting, and style.

Close-up of a glass bottle slowly dripping water into the soil
of a green pothos plant on a sunny windowsill, shallow depth of
field, soft morning light, slow push-in camera, realistic,
calm mood.

• Generate 2–4 variations per shot and keep the best.
• Keep prompts consistent (same lighting and style words) so clips match.
• Avoid real people’s likenesses and trademarked characters.

Option B: Animate still images

Create consistent images first, then animate them with an image-to-video tool. This often gives you more control over the look. See Best Prompts for Image Generation with Midjourney for prompt ideas.

Option C: Use an AI presenter

Paste your script into an avatar tool, choose a presenter and voice, and generate. This works well for tutorials and internal training. Only use avatars and voices you have the rights to use.

Step 4: Add a Voiceover

1. Paste the voiceover column into an AI voice tool, or record it yourself. Your own voice builds trust.
2. Choose a voice that matches the tone and adjust the speed. Slightly slower than normal speech usually works best.
3. Export as WAV or high-quality MP3.
4. Never clone someone else’s voice without explicit permission.

Step 5: Edit Everything Together

1. Import your clips and audio into an editor (CapCut, Descript, DaVinci Resolve, Premiere Pro, or similar).
2. Place the voiceover first, then lay clips over it to match the script timing.
3. Use auto-captions, then proofread them. AI transcription makes mistakes with names and jargon.
4. Add text overlays from your script table.
5. Add royalty-free music at a low volume under the voice.
6. Export at your platform’s recommended resolution and aspect ratio.

Step 6: Review, Label, and Publish

• Watch the full video on a phone before publishing.
• Check for visual glitches typical of AI, such as warped hands, flickering text, or objects morphing.
• Follow platform rules on labeling AI-generated or altered realistic content. YouTube, TikTok, and Meta have disclosure policies.
• Ask AI to draft a title, description, and tags, then edit them yourself.

A Complete Beginner Example

Goal: 45-second Instagram Reel about vacation plant care.

Workflow: Script table from an AI assistant (10 min) → 6 generated clips (30 min, including retries) → AI voiceover (5 min) → edit with auto-captions and music (30 min) → review and publish (10 min).

Total: roughly 90 minutes for a first attempt, and faster once you have templates.

Common Mistakes

• Trying to generate a long video in one prompt. Build it from short shots instead.
• Mixing wildly different visual styles.
• Skipping caption proofreading.
• Ignoring copyright and likeness rights.
• Expecting perfection on the first try. Retries are part of the process.

Worked Example: Writing Prompts for a Consistent 6-Shot Video

Consistency is the hardest part for beginners. A useful trick is to define a style block once and paste it into every shot prompt.

STYLE BLOCK: realistic, soft natural morning light, warm color
grading, shallow depth of field, calm mood, 9:16 vertical.

Shot 1: A person packing a suitcase while glancing at houseplants
on a shelf. [STYLE BLOCK]
Shot 2: Close-up of a plastic bottle with a small hole pushed into
plant soil, water slowly seeping. [STYLE BLOCK]
Shot 3: Plants grouped together in a bathtub on a damp towel. [STYLE BLOCK]
Shot 4: A self-watering globe being placed into a pot. [STYLE BLOCK]
Shot 5: Time-lapse feel of light moving across a room. [STYLE BLOCK]
Shot 6: The person returning, smiling at healthy plants. [STYLE BLOCK]

What to expect: some shots will look great on the first try, while others (often anything with hands or text) may need several regenerations. Keep the best take of each shot and don’t be afraid to simplify a shot if it keeps failing, for example a close-up instead of a complex action.

Choosing the Right Tool Type

Your goal	Best tool type	Why
Explainer or training video	AI avatar/presenter	Fast, consistent presenter from a script
Social clip with cinematic visuals	Text-to-video or image-to-video	Visual variety, short shots
Talking-head video you recorded	AI-assisted editor	Auto-captions, silence removal, quick cuts
Faceless YouTube narration	AI voice + b-roll	Clear narration over visuals
Product demo	Screen recording + AI editor	Accuracy matters more than generated visuals

Troubleshooting Common AI Video Problems

1. Flickering or morphing objects: Shorten the clip, simplify the action, and describe fewer moving elements.
2. Characters look different in each shot: Use the same reference image (image-to-video) or a character reference feature if your tool has one; repeat the exact description.
3. Garbled text in the video: Don’t ask the generator for text. Add text overlays in your editor instead.
4. Voiceover sounds robotic: Add punctuation for pauses, try a different voice, lower the speed slightly, or record yourself.
5. Audio and visuals out of sync: Cut visuals to the voiceover, not the other way around.
6. Export looks blurry on social media: Export at the platform’s recommended resolution and avoid re-compressing a file multiple times.

A Simple Checklist Before You Publish

• Script read aloud and timed
• All shots match in style and lighting
• Captions proofread (names, numbers, jargon)
• Music is licensed or royalty-free
• No real person’s likeness or voice used without permission
• AI disclosure added if the platform requires it
• Title, description and thumbnail reviewed by a human

Practical Example Prompt for Titles and Descriptions

Here is my video script: [paste]. Write 5 YouTube Shorts titles under
50 characters, a 2-sentence description, and 5 relevant hashtags.
Avoid clickbait and don't promise anything the video doesn't show.

Budgeting Time and Credits

Most AI video tools work with credits or monthly limits, and each generation (including failed ones) usually consumes some of them. To avoid running out halfway through a project:

• Plan every shot in your script table first so you don’t generate random experiments.
• Test prompts at the lowest quality or shortest length your tool allows, then generate the final version.
• Reuse good shots across videos where it makes sense, such as intros and outros.
• Keep a prompt log with the exact prompt and settings of every shot you liked, so you can recreate the style later.

Check each tool’s current plan page for how credits are counted, since this differs between services and changes over time.

Frequently Asked Questions

Can I make AI videos for free?

Many tools offer free tiers or trials, often with watermarks, lower resolution, or limited credits. They are enough to learn the workflow.

Can I monetize AI-generated videos on YouTube?

Platforms generally allow AI-assisted content but prioritize original, valuable work and may require disclosure of realistic synthetic content. Review the platform’s current monetization and AI policies.

How long can AI-generated clips be?

It depends on the tool and plan. Most generators produce short clips, which you combine in an editor to make longer videos.

Do I need a powerful computer?

No. Most AI video generators run in the cloud through your browser. Editing works on most modern laptops.
