The ultimate guide to Synthesia.io and reviews

AI-generated content has become both remarkable and controversial, pushing the boundaries of what we can achieve with nothing more than a mouse and keyboard if we apply ourselves and tap into those hidden stores of creative energy. Video content, audio tuning, voiceovers, and digital art are all fair game with today's artificial intelligence.

This time, we’re focusing on video editing and Synthesia.io, a video-generating tool.

What is Synthesia?

Synthesia is an AI video-generating platform (or, you could say, a text to video service) aiming to provide its users with a more affordable alternative to traditional video creator tools and techniques. It removes the need to hire video editors and rent out studios, making high-quality video production accessible with just a few clicks.

Synthesia is a powerful video creation tool with plenty of templates to work with, which those less experienced will surely appreciate. It is simple enough for quick social media personalized videos and digital marketing videos, as well as YouTube videos, class projects, or onboarding explainer videos. Still, it is also powerful enough to accommodate demanding users looking to create professional videos at home.

The different features of Synthesia.io

All the best AI tools are versatile and Synthesia is no exception. The platform offers:

  • Custom-made AI avatars: With these custom avatars (i.e., digital actors), you can bring your script to life without having to be in front of the camera yourself. No more excuses for being shy!
  • Text to speech features: Synthesia is a fantastic TTS tool, supporting several languages and featuring many high-quality voices that will remove the need for recording. Simply work on your script and let the AI presenter of your choice read it aloud.
  • Built-in screen recorders and customizable templates: If you want to capture your screen and play around with pre-made video templates, Synthesia has got your back. You can use it as an all-in-one app and ditch alternatives like OBS to save time and resources.

The common challenges with Synthesia.io

Synthesia is versatile, but it would be unwise to think it is perfect since there’s no such app. Some of the most common problems people encounter when using Synthesia include:

  • Resolution issues: Sometimes, the video resolution refuses to cooperate and becomes blurry, forcing you to redo the video. That goes against the time-saving tenets the app is supposed to uphold and is not a feature of high-quality videos we would like to share with potentially massive audiences.
  • A lack of audio tuning settings: While Synthesia can be used as a TTS tool, it is not one at its core. Compared with Speechify, which has TTS down to a fine art, it is somewhat lacking in the audio settings department. Unlike Speechify, it won’t give you much freedom when playing with pitch, speech emphasis, accents, etc., all of which are indispensable parts of an engaging video.
  • A lack of solid backup features: Losing your progress is horrible, especially after you’ve spent hours on a new project. Sadly, Synthesia suffers from a lack of reliable backup options that would let you go on working offline. When using Speechify, for example, and making a voiceover, you can back your files up at any time and access them anywhere.

Using Speechify for your high-quality voiceover needs

All in all, Synthesia will cover most of your video-generating needs, but if you need to add voiceovers or breathe more life into your script, you’ll be much better off using an app like Speechify.

Speechify is, above all else, a text to speech tool, so it’s not surprising that it allows for more freedom whenever you need to fine-tune your audio files. It’s richer in customizable parameters and supports dozens of languages than even the best video makers out there.

Speechify is simply better when it comes to voice quality too. Long gone are the days of robotic, chatbot-like TTS tools like Microsoft Sam. With advanced machine learning and innovative APIs Speechify is based on, you can get authentic voices in real-time, combined with background music and various other sound effects. Speechify also works with all sorts of apps, from Google Docs to Word and Powerpoint.

It bears mentioning that more flexibility does not come at the price of reduced accessibility. On the contrary, there are plenty of tutorials and training videos explaining all the key features of Speechify, so you’ll never feel lost trying to invigorate your script by introducing some quirks to it. And perhaps it is needless to say, but Speechify customer support will be glad to assist you should you have any inquiries. Try Speechify for free today and take your voiceovers to a new level.

FAQ

Is synthesia.io free?

In addition to the $30/month plan we mentioned, there is only a free trial available at Synthesia.io. That is, there are no subscription-less plans.

What is the difference between synthesia and synesthesia?

These two terms sound similar, but their meanings couldn’t be more different. Synthesia is an online video editing software and video generation tool, while synesthesia is a type of perceptual phenomenon that causes stimulation of one of the senses to trigger other senses too. For example, some people see letters as intrinsically tied to a color.

How do you make AI videos for free?

There are many types of video editors that you can use for free, but none of them will offer satisfying results. You can a try free demo for something like Synthesia and see how the quality provided by free tools is nowhere near that of a more premium piece of software. Don’t forget to pair whichever video editor program you choose with Speechify for better and more realistic voiceovers.
