Our use case was we built, like, kind of an automated pipeline that would take Google slides that we created, and it would automatically create videos from those slides with an avatar.
Synthesia offers high-quality automated content creation with features like animation and realistic avatars. Its speed, efficiency, and user-friendly interface save time and resources, streamlining workflows via integrations with tools like ChatGPT.

Our use case was we built, like, kind of an automated pipeline that would take Google slides that we created, and it would automatically create videos from those slides with an avatar.
One improvement in our organization was that we could produce videos quickly. It increased our footprint as a small team, making us look like a bigger team because of that automated pipeline.
There's a learning curve with Synthesia, but towards the end, it enabled us to produce, generate, and edit videos correctly.
The most valuable feature is the fact that we're able to automate those videos. That was a big part and developer workflow was pretty nice.
I would like to have a little bit more of a place to have testing be able to test more because we're being charged on a utilization level. And sometimes, we have to scrap what we created.
It'd be nice to just use that quota for actual production videos and have something.
It would be nice to just have an audio track to check the audio because we're in a technical field, and the avatars' voice rendering gets strange on certain words that we use. It gets strange with certain words that we use.
We use a lot of acronyms and it's just not pure English. So it'd be nice if we didn't lose our credits on testing rather than if we just had an audio tracker to cut a lot of that stuff. So, the development testing workflows could have been improved at that time.
With the voice rendering, if we could have some type of AI that could understand the state, and the company, it could probably make a lot of improvements on the language, for clarity, for spelling, it could check a lot of that stuff for us.
If it had some type of intelligence to it, we'd be able to pronounce certain things and understand the context of certain things. So, just a level of smarts in there would be a huge improvement.
I used it for a year. We were pretty current on the version at the time and did a lot of upgrades.
We did have some times when Synthesia was down. That kind of slowed down our process. We had that happen a couple of times.
So, the service itself was stable for the most part. But we did have a couple of times when it crashed. It wouldn't generate videos or things like that. It's probably some kind of bandwidth issue.
I saw some improvements with the avatars and how they became a little less and less robotic, and they looked less and less like avatars after a while. So I thought those improvements were nice.
Once we got the templating issues down and figured that out. Then, the overall pipeline became pretty simple and reliable after some time.
We're a very small team, so we didn't have any kind of scalability issues.
The problem was that we had a small team, and we only had one account. Because of the pricing, we were not able to get multiple accounts. We just had one account.
So there was no scalability because if somebody was there doing stuff, someone else could also log in. We had scalability issues because we could only have one account for our team.
We talked to the technical team about a couple of things here and there. We had some calls trying to figure things out. Overall, it was okay because once we got those early bugs, we had no issues afterward.
In the beginning, it was kind of a learning curve trying to get that pipeline set up correctly.
But once it was set up, overall, it was okay.
We have some issues with the templating now. So I would like to see the templating definitely improved with it because some of the templates really screw up our process.
If it has some kind of intelligence to understand, like, how many slides there had to be, how many things like that if it could kind of be a little bit more dynamic, so you don't have to create all the templates with exactly the correct amount of slides to begin with for it to be able to understand what to do.
If it could dynamically say, "Okay, I could see that you have 18 slides, obviously. We're gonna need 18 slides for this," and that kind of templating format was kind of tricky at first. But once we got it down, it would make it a lot easier after some time.
It helped generate more on-demand. Because we have an on-demand video-based curriculum at our university. So, it helped increase the number of people taking the courses.
We hit our quotas quite quickly. So we are definitely limited to how much testing we can do, which is kind of a problem.
For what we used it for, we definitely ran into issues with being able to use be it due to the price because we didn't have enough credit.
Definitely see if you can get some test development credit to do that if Synthesia has any improvements along that side. That would be helpful.
When we were trying the product early on, Synthesia didn't have as much templating, but maybe they've got some of this worked out by now. I haven't used it extensively in the last probably six months, so I can't say anything new that they've done, but I would definitely ask about templating and test development credit.
Just make sure you know how to use templating, how to use the test resources, and how to use the automated pipeline with Google Slides. Those are the three big things.
Overall, I would rate it a seven out of ten.

I use Synthesia in my company for some of our global projects. With Synthesia, I need to create multilingual pieces of training, and I primarily focus on languages like Spanish and Portuguese.
Synthesia has many benefits for my company, and I can list some of them. Synthesia is a tool you can use rapidly, so it helps me to be efficient and meet deadlines. Synthesia is cost-efficient because you don't need to hire different people who know different languages, which saves a lot of money. If you use Synthesia, you don't need to hire actors or voice-over people.
Synthesia helps with consistency, so when I do a project in Spanish, I know that it translates and uses the Portuguese version in our company. Synthesia ensures that both language versions, Spanish and Portuguese, are consistent in quality. With Synthesia, you have the same avatars or the same look despite the language changes.
Synthesia allows you to be really creative, and I use it for role-playing. I think Synthesia helps me make my work more engaging.
With Synthesia, I hope that some of its features related to the translation portion will come into place soon. If I create something in Spanish with the solution, I either have to send that content to a translator or use Google Translate and get a native speaker to review the text before I put it back in Synthesia and download it into another language. I think Synthesia could have a built-in translator, which would be amazing and extremely helpful since it would make the whole process much more time-efficient.
Even though I love that in Synthesia, the voices are very clear, and its ability to enunciate words very well, everything in the solution still sounds and looks slightly robotic. Synthesia has come a long way, but I can see that in a couple of months, it will continue to improve further.
I have been using Synthesia for probably five months. I use the solution's latest version.
I personally have not had any issues with the product's stability. Stability-wise, I rate the solution a ten out of ten.
Scalability-wise, I rate the solution a ten out of ten.
I have past experience with Vyond.
In terms of the product's initial setup, I can say that it is extremely user-friendly. I think you can quickly learn the basics in Synthesia, and as you play around with the tool, you can get a little bit fancier, so in my case, I like to incorporate music when I edit and use videos in the background. You can use images and videos from other sources, so you are not tied into Synthesia's videos and images.
The solution is deployed on the cloud. I use a username and password to access the tool.
I can say that I have seen a return on investment based on the amount of time that Synthesia has saved for my company and the feedback that my company has received from its users, who found it engaging, which in turn made them like it. I think that my company wants to find that perfect fine line so as not to overuse the solution since we don't want people not to find it to be special anymore.
I did not evaluate other tools in the market against Synthesia since I considered it to be a go-to tool for me.
I was suggested to make use of Synthesia's diction features. It definitely occurs at times when a pronunciation will not be what you want it to be, and Synthesia's diction feature turns out to be a great component because you can just type in what you want a word to sound like.
I love the tool, but I still think it has potential for improvement, so I rate the overall product a nine out of ten.

I use it to create training videos. Many of my clients provide me with written content that they want to convert into video format. Some companies provide PowerPoint presentations, while others give me scripts to turn into videos. Clients contact me to produce videos based on their content. But I've also used it for creating TikTok videos, social media content, and even commercial videos and testing.
As a freelancer, my clients have experienced cost reductions when creating videos. Using AI tools like Synthesia, as opposed to Adobe Premium and similar software, has made video production more cost-effective. This has been well-received by clients and has led to positive reviews.
The feature I find most valuable is animation. Compared to other AI tools I've used, like Kaspersky and others, they lack the flexibility and automation that this tool offers. It really enhances the aesthetics of my projects and allows me to be more creative, unlike those other products which are quite rigid and limited in what they can do.
One aspect I'd like to see improvements in is the customization of avatars. Often, clients want to use their own faces or company representatives as avatars, but they find the current pricing of a thousand dollars for a custom avatar to be too expensive. This cost is a turn-off for them. I hope you can work on this by either reducing the cost or finding a solution to make it more affordable for users who wish to have a personalized avatar.
One concern is related to the cost, which some clients have raised. The second issue pertains to moderation and time zones. I believe they should address this concern because, recently, during testing, I encountered a situation where customer service was unavailable to manually review a video demo. This manual review process is important to ensure that the video complies with their terms and conditions and doesn't violate any guidelines. The video review process can take around five minutes, and it's crucial to ensure that users are creating content within the specified terms and conditions.
I have been working with Synthesia for the past six months.
The only issue I've encountered is with video generation. There have been instances where my videos were placed in moderation. I reached out to their customer service, but they were not available at that time. I believe they should improve their customer support's availability and align it with various time zones. This way, they can better assist users when they need it, ensuring that I don't have to wait for an extended period when trying to generate a video for a project.
It is scalable. They offer two, or maybe three, packages. Initially, there were just two: a personal account or membership for individuals and a family plan, which covers around ten seats. They also have an enterprise option for larger teams, accommodating over fifty users. This scalability is useful for various projects. For shorter ones, the personal account suffices. However, for more extensive projects, such as creating long videos, it can be challenging with the limitations of a personal account. In such cases, you might need to contact their support to upgrade your account to an enterprise level, allowing for more effective usage without the need to split the project into smaller segments.
Setting it up is straightforward and user-friendly, even for those who may not be highly tech-savvy. When you sign up, the interface is clear and self-explanatory, making it very easy to use.
I have my personal account. However, when a project requires an enterprise account, I advise clients to get their enterprise accounts, and I work on those. Some clients prefer not to use my account and want me to use their own. In such cases, they provide me with their login details, and I create the videos on their accounts. This setup gives them control and ownership of the content, although it can be a bit tricky if they lack familiarity with the platform. I handle the costs, as well as any new features or enhancements they want to add to their personal accounts. They don't get access to edit the video directly in my account, so I encourage them to use their own personal accounts to have easy access to future edits.
The new pricing is fair and competitive. It compares well to other options on the market. The cost ranges from three dollars to approximately twenty-nine or even thirty dollars, with some specialized packages reaching the thirty-dollar mark.
I will request this from them, depending on their enterprise focus. We are a sizable organization, and I would like to see if they can provide a solution tailored to enterprises. We have been using their platform for remote video production in our central installation business, and it has proven to be cost-effective. It has complemented our cost-saving efforts, as we used to spend a significant amount on both remote and on-premises solutions. Transitioning to their platform has been smooth, and it has worked well for us. If it continues to perform as expected, it might make sense to reduce our dependence on other HES platforms.
Overall I would rate it a nine out of ten.

We are using Synthesia to create videos.
When I need training solutions, it provides training videos.
The AI is the most valuable feature.
The video part needs improvement.
I have been using Synthesia for four months.
The solution is stable.
The scalability depends on the budget.
The technical support team is good.
Previously, I used Adobe Suite and we switched as Synthesia because it has AI.
The initial setup is straightforward.
I have seen a return on investment.
The solution is a little pricey and should be made cheaper.
I rate the overall solution a nine out of ten.
I create educational materials for organizations with a workforce of around forty thousand employees. These materials include pre-call briefs, instructional videos, and an alternative to email communication. Instead of relying solely on email, I produce concise videos that convey messages or updates to colleagues and teams effectively.
It provides the ability to produce a substantial amount of high-quality content promptly. This results in a significant impact as viewers often cannot distinguish whether it's created by AI or a human. The content tends to generate a lot of comments and engagement because it holds people's curiosity and their attention effectively.
It offers several significant advantages over working with human presenters. When creating learning templates with humans, you often face challenges such as multiple takes, script errors, and discomfort in front of the camera. With this solution, you can select avatars, write scripts, and ensure flawless delivery, eliminating these issues. There is no need for post-production as the content is ready to be shared as soon as it's created. It enables to easily modify the content, and the original link will be automatically updated. This is a significant improvement over the traditional approach, where errors or updates necessitate taking down content, re-recording, and reposting. Another remarkable aspect is its user-friendliness. It's so straightforward that I believe most people could use it right out of the gate. Personally, I started using it without any prior research or watching tutorial videos, and it was remarkably intuitive and easy to navigate.
One of the issues we face is the variability in accents; there are hundreds to choose from, but some work better than others, and pronunciation can sometimes be subpar. Facial expressions may also not always be entirely accurate. Providing the capability to feature two avatars on-screen simultaneously for interactive communication would be a valuable enhancement. Improved transitions between different segments of the content would also enhance the overall experience.
I have been working with it for nine months.
I experienced excellent stability with this solution. It has never crashed on me, consistently delivering the expected results. While content processing may take around ten minutes, it has been a reliable and smooth process.
The scalability of this technology is one of its advantages.
I have reached out to their customer support team with questions, and they have consistently provided prompt and helpful responses. I haven't encountered any technical glitches, data losses, or content disappearing.
Positive
Previously, we used to create video content ourselves, and we still do on occasion. This manual process came with its share of challenges, including lighting issues, sound problems, and the need for post-production work using Adobe Premiere. We also utilized a tool called XSplit for recording, but it was often overly complex.
The initial setup was quite straightforward.
I have been able to create numerous videos, and I'm still in the experimental phase, which is what makes it so exciting. There are no limitations, and I can be as creative as I want, so I have definitely witnessed the payoff with the product.
When considering scaling up our usage of this technology, I did find it somewhat costly. It begins at around four thousand dollars for a full subscription, and although the price per subscription decreases when purchasing more, it can still be a bit of a hurdle, especially for limited content needs.
It is an incredibly user-friendly and intuitive tool and there are excellent learning resources provided on their site, which I highly recommend exploring. One valuable resource I found was a guide on how to craft a podcast, covering topics like the hook and storytelling techniques. I would recommend starting with the basic subscription, which provides about twenty minutes of usage per month. It's a cost-effective way to familiarize yourself with the product and create content. This allows you to experiment and see the benefits firsthand without committing to the full subscription upfront. The flexibility to cancel the subscription at any time is a significant advantage. If you opt for this solution, I would say that it is essential to have someone imaginative and creative in charge of scriptwriting and content creation. The impact of the content largely depends on the creativity behind it. It's crucial to understand that writing for spoken dialogue is different from writing in a standard written format. Creative content writers can make the dialogue emotionally intelligent, thought-provoking, and empathetic. Overall, I would rate it ten out of ten.

I evaluated the tool for internal training projects.
Synthesia is very good for internal training and messaging as it saves time. Previously, for me to create an asset, I needed to use several resources, including actors, studios, and lighting, all of which took considerable planning.
With Synthesia, it is easier. It has a wide range of digital actors, integrates with generative AI solutions such as ChatGPT, and continues to evolve with new features such as its new translation tool.
This makes distribution to diverse audiences much simpler.
I would be reluctant to use the solution for customer-facing products. The digital actors’ lips are typically out of sync, and their mannerisms can sometimes feel off. This can potentially create a disconnect with the audience. It is for that reason; real actors would be preferred for customer-facing assets. They have a greater capacity to show empathy, excitement, and passion in their delivery.
I have been using the solution for about a year.
The stability is fine. It’s a fantastic product and perfect for certain use cases. My only reservation would be for customer-facing productions. The lip synchronization can sometimes look like a badly dubbed film and if the avatar looks off camera, then psychologically it looks as if they are lying
I am the only one using the product in my organization.
I have never contacted the technical support team. It is a very easy product.
There is no installation required. It's a web-based, SaaS product. We just log on to the portal. It is also super easy to use. What's my experience with pricing, setup cost, and licensing? The solution is cost-effective and relatively cheap. I also believe the product is coming out with new personal and enterprise packages.
I've only used it to evaluate. If I were to recommend it to someone, I don't think that the cost of the product would be a detractor.
The solution is cost-effective and relatively cheap. I believe the product is coming out with personal and enterprise packages. It is value for money. I've only used it to evaluate. If I were to recommend it to someone, I don't think that the cost of the product would be a detractor.
I have used the solution for a couple of projects. It's a product that I actively follow. It has some really strong points, but it has some slight issues as well.
Everything that Synthesia is doing can be done with other tools, but the beauty of this product is that it is all collated into a nice, easy to use package.The software is a game changer and deserves all of the hype and praise it gets on social media. The tool is invaluable for companies that can't afford a studio or perhaps need to change content on the fly, especially in learning and development.
The digital actors are not quite on par with human actors, which we would expect.
Overall, I rate the tool a nine out of ten.

I am an instructional designer. Thus, I use the product to create videos for various learning courses.
The product helps us efficiently in making videos. It is very easy to make changes in the script and works well with other programs as well. We use it in combination with Articulate Storyline. We can create video graphics quickly compared to third-party vendors. It is easy to learn as well.
The product’s Avatar feature looks realistic. It offers different voice and graphic options as well. It works efficiently in conjunction with other products.
There could be animation features for Avatars. It would help us create cartoon animations using Synthesia instead of Articulate Storyline. Additionally, interactive features still need to be included. The product’s voice diversity is not that good. Sometimes, the standard voice does not match the movement. It needs improvement.
I have been using Synthesia since last December.
The product is stable. However, they should provide us with a tutorial whenever they make changes to explain how it would affect the overall application.
I rate Synthesia’s scalability an eight or nine out of ten.
The product is deployed on the cloud. The initial setup was straightforward and user-friendly. I took assistance from an expert to work on the process.
We evaluated a product where we could draw animation and communicate through videos.
I recommend Synthesia and rate it a nine out of ten. I advise others to identify their use cases and evaluate if the product meets those requirements. We wanted a product that creates videos quickly and is easy for all team members to use.

Synthesia's use for me was related to training purposes. With Synthesia, I could create instructional designs for training courses meant for a major corporation, the military, and one of my personal projects.
My company used Synthesia to help us with compliance training, and it was used to provide feedback during instructional assessments. I have used Synthesia to create introductions for a website on which I was working. I have also used Synthesia for my e-portfolio and to articulate a storyline for an e-challenge project.
In Synthesia, the avatars can be an area that can be considered the product's most valuable feature.
In Synthesia, there are plenty of areas where improvements are required. The main area of concern in Synthesia stems from its ability to add multiple elements onto a timeline, an area where I feel the product lacks in terms of its intuitiveness and user experience, and I had even complained to the company after it became nonfunctional. Though Synthesia made some changes to get the product working, it still is not as seamless as some other timeline-based non-linear editing software I have used.
I would like to see better use of audio in Synthesia. I think Synthesia's audio component could be drastically improved. There is room for improvement on how the audio part is integrated into a project and how it is manipulated and edited, along with how the volume and placement of the timeline are edited. Once a video is created, that process is kind of convoluted. I think there should be an easier way to determine whether your video is done and, if it needs to be corrected, how to correct it since these areas are not very intuitive. There's not a whole lot of direction available anywhere on how to do things well on the platform.
I have been using Synthesia for a year. Speaking about the version, I have experience with Synthesia STUDIO.
Stability-wise, I rate the solution a six out of ten.
Scalability-wise, I rate the solution a four out of ten.
I rate the technical support a six out of ten.
Neutral
I used a program that is very similar to Synthesia called D-IB, which was a lot easier to use. Though D-IB didn't have as many features and content as Synthesia, its avatars were a little bit more authentic and looked a little more real.
The product's initial setup was easy, and it wasn't hard at all. It is just that the product's user experience is not user-friendly.
The solution is deployed on my browser, Google Chrome.
Synthesia is a reasonable and competitively-priced product.
The only option I considered during the evaluation was D-IB.
You need to be patient while using the tool. I avoid trying to do any projects that are very complex, especially when the tool's use is in its beginning stages. Maybe in the future, there will be improvements in the tool's GUI and interface. Right now, Synthesia is just for doing easy projects that don't require a lot of complex interaction with the user.
I rate the overall product a seven to eight out of ten.

We use Synthesia for creating animations and for voiceover purposes.
The application helps our organization with creating video animations and voiceovers.
The product has a valuable feature for creating voiceovers.
There could be an option to minimize the character’s expression in the animated videos. Also, they should work on the feature to include two voices simultaneously in one video.
We have been using Synthesia for six months.
The product is very stable.
I rate the application’s scalability an eight out of ten.
The initial setup is easy. There could be more features to control and customize the voiceovers and video creation per our requirements.
I recommend Synthesia and rate it a nine out of ten.
The company I worked with used Synthesia to create learning videos for our customers and partners.
Synthesia improved our organization by streamlining a lot of the work that would have gone into video production and making it more dynamic. The solution also increased the turnaround time and made everything very, very fast.
Synthesia provides the ability to have the characters say nearly anything that you need them to, and its pronunciation library gives the absolute correct pronunciation that you need for any number of words. It allowed our characters to see the name of the company correctly without a lot of shortcuts or workarounds.
Synthesia's video editor needs to be improved. We're working with our Synthesia rep to get this issue at the forefront of the developer's minds. I haven't used it in a few months, but the last time I picked it up, the video editor wasn't that great.
Synthesia should include a good audio editor and a better timeline UI.
I have been using Synthesia for nine months.
Synthesia is a very stable solution.
I rate Synthesia an eight out of ten for stability.
Although it can scale, the price points dramatically increase once you hit a certain number of users. At that point, it's much better to either have a small team working with the tool or go all in and have an enterprise-wide solution.
I rate Synthesia a seven out of ten for scalability.
Synthesia’s technical support was very good.
Positive
We previously used WellSaid Labs.
We have seen a high return on investment with Synthesia.
For what it is, I think Synthesia is priced pretty reasonably, but smaller businesses might be uncomfortable with such a large price tag. For what it is, the amount of time it saves, and the amount of work hours it saves, Synthesia is definitely worth the price.
Synthesia was deployed on-cloud in our organization.
I would ask users to give it some time, look at all of the features that Synthesia offers, and be very open-minded. Also, it's best not to let a technical person evaluate Synthesia. Instead, let someone who is in video production or graphic design evaluate it because they are the ones who will understand the full capabilities of the tool.
Overall, I rate Synthesia a nine out of ten.
