How to create a video with Synthesia

When I log into the platform for the first time, it shows a welcome video that guides me through the main features of Synthesia. There are also tutorial videos you can access from the dashboard.

I can select an avatar from the avatar button in the left-hand side dashboard. It is also possible to preview how the avatar looks and moves and how it speaks a specific intended language. Searching for avatars in Synthesia is easy since you can find your favorite avatar by typing "I am looking for a young man with white clothes" or "I am searching for a male doctor."

In my experience, Synthesia offers the most extensive library and diversity of stock avatars. You will find the perfect avatar no matter what video you intend to create. And there is always the possibility of creating a custom avatar.

synthesia avatar selection

There are two types of custom avatars in Synthesia. WebCam avatars are those that can be created using a webcam or PC camera, and custom avatars require filming in a studio.

You can show the entire avatar body, circle (with customizable background color and shadow), or only voice.

Changing the avatar position in pre-defined parts of the screen or setting it manually in a specific area is also possible.

Some avatars can move with micro gestures: nod, heads yes, head no, and eyebrows up. Synthesia updates its avatars frequently, and many avatars can perform various gestures, including nodding, shaking the head, agreeing with a yes, and looking surprised. Although Synthesia avatar gestures look natural and human-like, these can´t surpass Colossyan´s emotions, aging and avatar expressions.

Synthesia offers the ability to customize avatars, allowing you to create videos that reflect your brand's unique identity. You can choose from a wide range of brand colors to personalize your avatar's appearance and ensure a cohesive and recognizable visual representation. With this feature, it is easy to strengthen your brand's presence by recoloring clothes and adding logos to your avatar.

Synthesia features lots of pre-made video templates. This is a useful resource to start creating a video instead of a blank canvas. These templates can be customized to your liking, but it is also possible to start a template from scratch.

Customization is available for any item, including backgrounds and fonts. Fonts are fully customizable, with colors, size, justification, and more options.

There is a vast library of royalty-free media assets to fine-tune your video. Synthesia gets Images and videos from Shutterstock and animated and static icons from Icon8. The variety and quality of these media set this platform apart and add lots of value.

synthesia graphic assets

Furthermore, you can also upload your own media and logo to keep consistent branding.

There is also a comprehensive library of music assets. You can add music from a Shutterstock library, and you can play any soundtrack to test if it is the right one for your video before adding it to the scene. There is also the option to upload your own music file provided its format is MP3, OGG, WAV, AAC and FLAC.

Avatars can also speak your own voice, but the voice upload feature is only available on Enterprise Plan. Notice that voiceover upload is available on standard plans on Elai and HeyGen.

Synthesia editor is scene-based and not timeline-based as traditional video editors, so you have to work each scene separately.

Each scene can have its own script, and I must type it in the lower part of the screen. Here I can set language (from a library of 60+ available), voices from a library of 400+ available, and subtitles.

synthesia voice selection

I tested multiple English and Spanish voices. Their quality was excellent and indistinguishable from human voices. I can add pauses and select a specific word in the script to add an alternative pronunciation.

Scenes can have enter and exit animations, and you won´t find in any other platform the granular control that Synthesia offers in these items.

synthesia animations selection

The screen recording button lets you add visuals right from your screen, a helpful feature not always available in this type of platforms. This tool is useful if I want to record the whole screen, a certain area of the screen or a browser tab, trim the video and even sync the screen recording with the audio.

Synthesia has a built-in AI feature that helps to write a draft script. Based on your input, the system crafts a full script with scenes and voices. You must describe your target audience, topics, tone and more fields that include specific information and details. Once you consider the draft is complete, click on “generate script” and you will get a first draft. You can regenerate it if you think it needs improvement, otherwise go to the editor and you will find a script with scenes including an avatar and voices. Of course you can edit the script and any part of the video.

synthesia chatgpt integration

Once you are comfortable with the video, click play and check how it works. In this stage, avatars have no animation, and the video won´t show at full resolution. If everything is ok, click “Generate” and wait some minutes for the video to render.

The dashboard is intuitive and clean, and I didn´t experience glitches or frozen pages.

Admins can invite guests to review videos before publishing, but - as in similar tools - there is no formal review workflow available.

What sets Synthesia apart from its competitors

Onboarding and tutorials

Synthesia’s onboarding is light years ahead of competitors. No other similar platform offers such an extensive variety of resources to get started and get the most of its features.

synthesia tutorials

Their page contains many videos, webinars, beginners’ and advanced tutorials, and case studies. Furthermore, a dedicated help page has many resources to get the most out of the software.

Moreover, their YouTube channel has many videos and tutorials and is updated weekly.

Natural-Looking Avatars

Synthesia’s avatars possess a remarkably realistic appearance and natural movements, surpassing the limitations of most competitors. Lip-synching is also one of the best.

Ease of use and user experience

Synthesia’s intuitive user interface and streamlined workflow make it exceptionally user-friendly. Users can effortlessly navigate the platform, generating videos with a minimal learning curve and no previous experience.

Certified service providers

A vast network of certified service providers is available to help with video creation, course creation, translating, shooting custom avatars, or even outsourcing your entire video project.

Strong security and compliance

Synthesia is SOC 2 Type II and GDPR compliant, with SSO support. Security monitoring and compliance process are audited by Vanta, an independent company that tracks security and compliance.

If security and compliance are among your requirements, HourOne is the only Synthesia competitor offering SOC2  and GDPR compliance.

What I would like Synthesia to improve

Pricing plans

Synthesia should offer intermediate pricing plans since only one is aimed at individuals.

All Synthesia competitors offer many pricing plan options, so you can choose which is the best option for your needs.

A free trial

Although you can create a video for free on their page, you can´t know how the software works until you go for a paid plan. A free trial is a common practice in many software companies and it should be useful in Synthesia too.


Synthesia integrates with Shopify, WordPress, Unsplash, Pexels, Mindstamp, Vimeo, Tolstoy, Thinkific, YouTube, and more. Surprisingly, there is no Zapier integration to connect others applications. If your app is not on the list, you should check and HeyGen because both of them offer Zapier integration.

Their API is still in beta and not in active development at the moment of this writing.

Synthesia pricing

Synthesia offers three pricing plans:

  • Starter Plan: $22/month (billed annually) or $29/month billed monthly. This includes 120 minutes/year, 70+ AI avatars, 120 languages and voices, screen recorder, 60 templates and live support.
  • Creator Plan: $67/month (billed annually) or $90/month billed monthly. This includes 360 minutes/year, 90+ AI avatars, 120 languages and voices, 60 templates and live support.
  • Enterprise Plan: You can ask a tailored plan according to your needs.

Check the full pricing plans details on their webpage.

synthesia pricing


Remember that Synthesia pricing is based on a credit system, and 10 credits are equivalent to 10 minutes. Thus, a 1 minute video will take 1 credit, and a 1.5 minutes video will consume 2 credits.

There are lower prices on similar platforms. For example, Elai offers 15 minutes of video/month for $29/month and many pricing plans based on monthly video minutes. This pricing scheme also applies to HeyGen and Colossyan.

Synthesia reviews and support

I found that Synthesia score on G2 is 4.8/5 from 824 reviews, an excellent rating that tells us what customers think about this platform.

Synthesia improves regularly, and its customer-focused marketing is good enough to communicate it. In the upper right dashboard, there is an icon that shows platform updates and news about the platform.

synthesia dashboard

Regarding support, an icon on the lower left screen is always available to get in touch. This icon shows all the different ways you can get help or access tutorial resources. This is a useful approach; you don't need to exit the dashboard searching for a help page.

Three best Synthesia alternatives

I am  listing the three best alternatives below if you are still unsure about Synthesia. All of them offer free credits to try.


Regarding avatar quality, Colossyan is the only platform that compares with Synthesia.
You won't find many templates or stock avatars. Still, there are enough unique features in Colossyan, like avatars' emotions and aging, conversations, and outstanding ChatGPT integration.
Pricing plans start from $28/month with 10 minutes of video creation.

Read our Colossyan review here.


Elai is a Synthesia alternative with many features and continuous API development. Here, you have plenty of pricing plans, so it may be a good fit if you create a bunch of monthly videos.
With 80+ avatars, automatic translations, and valuable integrations, Elai offers an excellent price/benefit relationship.
Pricing starts at $23/month with 15 minutes of video/month.

Read our Elai review here.


Heygen has unique features like talking photos, face swap, and generative outfits. Synthesia doesn't offer any of these, so you can try them out with the free credits HeyGen offers.
Furthermore, it features 100+ avatars, 400+ video templates, and voice cloning, although avatar quality is below Synthesia's avatars.
Pricing starts at $24 for 15 minutes of video per month.

Read our HeyGen review here.


Synthesia Video Generator: My take about Synthesia

Overall, Synthesia offers an impressive AI-powered video creation experience with strengths in AI text to video creation and avatars quality. However, drawbacks like pricing plans exist, and other platforms like HeyGen and Elai offer better pricing options. Consider your specific needs, budget, and desired features before making a decision. As AI video generation evolves, its impact on diverse industries is exciting to explore.

I was impressed by Synthesia video quality, avatar quality, integrations, and how easy it is to create a professional-looking video in minutes.

By using Synthesia you can decrease video production costs dramatically. You can create 10 minutes of video for $30 ( or $22.50/month annually billed) with only your PC, something we couldn´t think of a pair of years ago.

As with similar platforms, you must go for higher plans to get the complete set of features. But in my experience, it’s worth the money.
