HeyGen tutorial: how to create an AI avatar video

HeyGen lets you create AI avatar videos without a camera, studio, or editing setup. This practical tutorial walks through templates, avatars, scripts, voices, translation, export, pricing limits, watermark checks, and what to review before publishing.

HeyGen is an online tool for creating videos with AI avatars. Instead of setting up a camera, microphone, studio, and editor, you choose an avatar, write a script, select a voice, and generate a video.

It is most useful for short explainer videos, product walkthroughs, customer onboarding, internal training, social clips, and translated versions of existing videos.

The important part is not the button that generates the video. The useful part is a clear script, a believable avatar, a natural voice, and a proper review before publishing.

When HeyGen makes sense

HeyGen is a good fit when you need video content quickly, repeatedly, or in several languages.

Common uses:

• short LinkedIn, Instagram, TikTok, or YouTube Shorts videos,
• a welcome video for customers,
• internal training,
• a simple product explanation,
• a service intro on a website,
• a localized version of an existing video,
• testing several versions of a marketing message.

It is less useful when you need a deeply personal message, real emotion, documentary footage, live reaction, or a situation where an AI avatar would reduce trust. Sometimes a simple phone video is the better choice.

What to prepare before opening HeyGen

Before you start, prepare four things:

• the goal of the video,
• the audience,
• a short script,
• the place where the video will be published.

Do not start with “I need a video about my service.” Use a more specific brief:

I need a 45-second video for small ecommerce owners. The goal is to explain that we help them answer customer questions faster. The video will be posted on LinkedIn. The tone should be practical, calm, and not too salesy.

Short videos work best when they say less, but say it clearly. One avatar, one idea, one next step.

1. Create an account

Open HeyGen and create an account. For a first test, do not start with a paid plan unless you already know what you will produce.

The free plan is useful for testing the interface, avatars, voices, and basic output quality. Expect limits, lower-resolution sharing, and a watermark. Before using HeyGen for a website, ad, or client project, check the current pricing and plan limits inside HeyGen.

Use a strong password and enable two-factor authentication where possible. If you need one, you can create it with the password generator.

2. Choose how to create the video

HeyGen gives you several ways to start. For beginners, these three are the most practical.

Quick Avatar Video

Quick Avatar Video is the fastest path. Pick an avatar, paste the script, select a voice, choose the video orientation, and generate a test.

Use it for a short announcement, a simple marketing clip, an internal message, or a first voice and avatar test. If you are unsure where to start, start here.

Template

A template is useful when you want a prepared structure, such as a product explainer, training video, announcement, or social post.

Choose the template by purpose, not by the flashiest design. Then adjust the avatar, background, text, music, and brand details so the video fits your audience.

AI Studio

AI Studio is better for longer videos or multiple scenes. Each scene can have its own text, avatar, background, and visuals.

Use it when you need more control over the script, several scenes, your own assets, or a video for a course, website, or presentation.

3. Choose an avatar

The avatar is the face of the video. Choose it for credibility, not novelty.

You can usually work with:

• a stock avatar from the library,
• an avatar created from a photo,
• a custom digital avatar,
• an avatar with a custom voice.

For the first test, use a stock avatar. It is the fastest way to understand the workflow.

If you create an avatar from yourself or another person, handle consent seriously. Do not use a colleague, customer, influencer, or public figure without clear permission. With AI video, this is a trust issue, not only a technical one.

4. Write a short script

The script decides if the video will be useful. An AI avatar can read the words, but it cannot rescue a vague message.

Start shorter than you think. For a first video, 30 to 60 seconds is enough.

Do customer questions take too much of your team's time?

We help small ecommerce stores prepare clear answers for the questions customers ask most often, so people get useful information faster.

First, we review your emails, orders, and common support cases. Then we create response templates your team or chatbot can use.

If you want to find where customer communication is slowing you down, send us a message and we will take a look.

Read the script out loud before pasting it into HeyGen. If you run out of breath, the sentence is too long. If it sounds like advertising filler, cut it down.

For longer scripts, you can quickly check length with the Word counter. For headlines and captions, the Text case converter can help.

5. Choose voice and language

Always preview the voice before generating the final video. Listen carefully to names, brands, abbreviations, and technical terms.

If the voice reads a company or product name badly, try:

• spelling the word phonetically,
• adding spaces between letters in an abbreviation,
• using a simpler sentence,
• changing the voice,
• uploading your own audio if your workflow supports it.

For business, education, and internal training, calmer voices usually work better than overly enthusiastic ones.

6. Set the video format

Choose the format by where the video will be published:

If you are not sure, start with 16:9 for general use or 9:16 for social platforms.

Use lower-cost tests before a final export. First check the script, voice, and avatar. Spend credits on the final version only after the basics work.

7. Generate a test, not the final version

Treat the first generated video as a review copy.

Check that:

• the avatar does not distract,
• the voice reads words naturally,
• the script sounds human,
• the pace is not too fast,
• captions match the speech,
• the background does not look generic,
• the call to action is clear.

If something feels wrong, edit the script first. Then adjust the avatar, background, and visuals.

Video translation and dubbing

HeyGen can also help translate and dub existing videos. In practice, you upload a video and generate a version in another language.

There are two useful options:

• Audio dubbing: translates or dubs the voice without lip sync.
• Video dubbing: also adjusts lip movement to the new language.

Video dubbing is more demanding and usually uses more credits. It makes sense when the speaker's face is visible. For a screen recording or presentation, audio dubbing may be enough.

Always review the full translated video. AI can mishandle product names, technical terms, numbers, and sentences that worked in the original language but sound awkward after translation.

Free plan, credits, and watermark

HeyGen changes plans and limits often, so treat public numbers as something to recheck before publishing.

At the time of writing, the Free plan is best seen as a test plan. Paid plans use credits. Credit usage depends on the feature, video length, and selected model. Advanced avatars, translation, or dubbing may cost more than a basic avatar video.

Before paying, check:

• monthly credit allowance,
• credit cost for one minute of your video type,
• option to buy extra credits,
• export resolution,
• watermark rules,
• cancellation rules.

If you create videos for a client, do not count only the final minute. Tests, edits, translations, and alternate versions can also use credits.

Can you use HeyGen videos commercially?

HeyGen states that generated videos can be used and distributed commercially when your inputs comply with its rules. In practical terms, do not use other people's faces, voices, photos, logos, music, or protected materials without rights.

Do not present an AI-generated video as purely human-made if that would mislead viewers. For sensitive topics, education, health, finance, and politics, transparency matters even more.

A simple disclosure can be enough:

This video was created with an AI avatar.

For ads, affiliate content, or product recommendations, disclose the business relationship as well.

Checklist before publishing

Before you send the video to a client or publish it, review:

• one clear main idea,
• a strong reason to keep watching in the first three seconds,
• natural pronunciation of names and brands,
• an avatar that fits the topic and audience,
• a background that does not look generic,
• readable captions on mobile,
• a specific next step,
• rights for third-party materials,
• AI disclosure where needed,
• correct format and resolution,
• watermark handling.

Common mistakes

A script that is too long

Beginners often try to fit everything into one video. The result is slow and hard to follow. One short video should solve one thing.

Language that sounds unnatural

Text can look fine in a document and still sound bad when spoken. Read it out loud before generating.

The wrong avatar for the audience

An internal training video does not need to look like an influencer ad. Choose the avatar by trust and fit.

Ignoring credits

AI video costs are not only the final export. Tests, fixes, and translations count too. Start with short tests.

Publishing without review

AI output can contain odd pronunciation, strange pacing, or a misleading phrase. Watch the final version from start to finish, ideally with headphones and on a phone.

Is HeyGen worth it?

HeyGen is worth considering when you need repeatable video content and want to avoid setting up a camera, studio, actor, microphone, and editor every time.

For beginners, the sensible path is:

• test the Free plan,
• generate a short sample video,
• review voice, avatar, language, and watermark,
• calculate the real monthly credit usage,
• move to a paid plan only when the workflow saves time.

If you need one personal message now and then, record it with your phone. If you need repeatable training videos, marketing clips, language versions, or script testing, HeyGen can save real production time.
