I can generate a video for explanation just by writing a script. There is no need to hire actors or set sets. It's useful when you need to give a little explanation to your organization.
I felt that corporate licenses were expensive and difficult to contract unless I continued to make videos. Also, with a personal license, the maximum length of video that you can generate per month is limited to 10 minutes, and it was impossible to add credits. Also, 10 credits will be given for a 10-minute video, but you consume one credit whether you make a 10-second video or a 1-minute video.
It is possible to send information that is a little eye-catching when communicating information to the organization or encouraging participation in some measures. In the past, it was necessary to ask a specialist to make an animation.
I can create professional videos from text in 50+ languages. Synthesia saves my time and allows me to publish news faster and more frequently on social networks
It can be a bit long. It is also a bit expensive, but it is worth it
Publish videos quickly and easily. Avoid the tedious side of making videos for which you have to start over and over again
The user experience, the semplicity and integrability
The price of the API, the Italian male language which is very unnatural and the avatars that could be done better.
Video content and low price personalized video
Synthesia is a fine online tool for developing online courses or having them created by a colleague. While you present this course then and then different languages. Top!
From text to spoken language is still not always perfect, but there is progress. To use it, it is certainly good.
Using Synthesia, I can put more courses online in less time. Or rather have a colleague put them up. I have more time to spare.
With a limited budget and no marketing staff, my open rates on video emails and social media posts have increased by 25% since using Synthesia. It is easy to use, and I appreciate the ethnic, language, and tonal diversity. I am encouraged by the frequent improvements added at no extra cost to us. The price is just right for our nonprofit budget.
Some of the phrase endings are a bit distracting - as if the avatar is gulping or swallowing the last word; however, this is not true of all voices and not a deterrent to our continued use.
We continue to engage with a younger audience and older adults who all spend a lot of time in front of screens. They report reading little and are more likely to watch a brief video than read our messages. Using Synthesia is also improving my messaging skills with better response rates.
Synthesia's intuitive platforms allows creating videos with an AI-created human being. I was impressed with the lip syncing and character animation capabilities. The new easy to use API will make creating content very convenient. I also appreciate that the team seems very responsive and eager for feedback.
Syntesia is a fairly young company, which means that some of the features I would like are in the development pipeline.
Synthesia has many applications especially in education and marketing. We are testing it for video surveys in emerging markets.
The quality of the AI avatars, the templates, the User experience
Missing preview before using credits! not enough templates not enough avatars
editing quick videos improving SEO
Best about Synthesia is that it is a full of possibilities tool for communication and customer experience.
The editing tools still do not give all the possibilities. You cannot test the video before finalizing it, background photos show sync failures. That reduces the quality of the final product.
We´d like to use Synthesia to resolve direct communication with our clients through our website and other digital communication channels.
The ease of adding a live character to a otherwise boring and less intuitive slideshow.
The fact that you cannot use a video to add the AI upon, you need to use a pptx format per exemple.
The cost for a custom made voice-over and different actors that would otherwise be needed for a video.
it basically covers every language kaing cross markiting very easy.
The avetars needs more Facial Expressions
An all in one platform , you can edit , you can do text to video , text to voice in multiple laguages , it helped us be more organized.
Updating our content is very easy as the scripts and slides can be changed very quick. This means we do not have to go back in and re-record a whole session just to change one thing.
Changing some of the templates can be difficult or changing the aminations which makes the video impossible to publish as it will not overrride the error.
Faster way to create training content for our company, and a easier way to update videos without having to recreate the whole video. Nice to not have a specific individual doing the voice over.
Creating a short video from start to finish is incredubly easy. The updated feature of creating videos portrait orientation is the most convenient for my company.
It should be easier to create templates from previously created videos. Needing to create them seperate of an actual video is a pain so I haven't bothered to create many.
Synthesia has drastically lowered the cost of creating videos. All our customers aren't necesarrily interested in real actors because of the high cost at scale. Synthesia helps us drastically lower that cost and offer an affordable alternative to their liking.
-saves us a lot of time in terms of production - lots of choice - captioning is good - like the gestures implementation - certainly a game changer for our company
- not enough choice in terms of export quality - would like the option to choose 4K - can't generate specific clips, causing us to generate an entire project again just to fix one small error - buggy, sometimes you'll press back from a project and it'll take you somewhere it shouldn't have. another example is when i started a Ai project, put all the information in and then it went back to the original menu and all work saved was lost. -generating can take very long for projects that are short - pasting in text will space it weird, won't put it in correctly forcing me to manually go through and space out all the text correctly... this particular issue needs to be fixed please :) - sometimes you'll put in normal text and the voice will take random pauses mid sentence for no reason - can look very unrealistic at times - some of the voices are very obviously robots
saves us a lot of time in terms of us filming, recording and setting up voice overs for clients. this benefits me as it cuts out all those steps and allows me to do it all from my workstation
The ability to easily edit videos without re-recording.
Limited female voice selection. In American US voices, limited to slight accents or white female voices. No African-American presence. Intonations are missing. Cannot form questions or exclamations. Speed adjustment is requested. The speed is too quick in some instances. The greatest feedback from users is that the speech is too fast. Am now downloading into Camtasia to edit the clip speed. In some instances, recording videos myself have turned out quicker.
When products have changed, rather than re-record a video, I can edit the text and republish.
The adaptability to use different avatars and voice choices to get the most impactful message possible in marketing campaigns.
There need to be more facial and body movements that are authentic.
This software has helped us develop better marketing tactics that gelp to gain consumer trust.
It is simple to use and user friendly...
More features for editing modes. Regarding Music and filters!
You can pitch your idea, story in a very short time frame and give your topic a new spin
Ease of use. Uniform videos. Ability to create our own avitar.
The length of videos that we can insert into the synthesia decks.
Onboarding uniformity.
It's super easy to use, great customisation and selection of avatars! It's very playful and can save a lot of time recording videos!
The voiceovers in german, spanish, french or italian sound still very robotic and not natural.
It saves time and costs when creating videos for our products or users.
The large variety of avatars and backgrounds
Avatars are too static, they always face cameras, and they're not enough diversity of clothing. And also the voice tones are a little bit limited.
Synthesia saves me the cost of hiring a model, booking a studio, and spending time creating videos.
It's quick and easy. Not all the voices sound natural, but there is one mens voice and one womens voice that sounds very human.
The pricing is weird. Supposedly, once you use up a certain amount of time, you can't make any more videos. That makes the product infeasible for larger projects. They should consider pricing by volume of video, not by month.
Creating training videos
The number of avatars and accents. But to be honest, I don't like the fact you cannot alter a rendered video (no access to source file) so you cannot make changes and render again.
The fact that I had to wait three or more days for render of video because you all went on holiday and didn't give a shit about your customers. As long as you were having a rest, that's great. Your customers can sit and wait while you're busy partying. I also cannot find the source file so if I want to make a change to a rendered video I have to start from scratch again. This is a serious weakness
online learning.
we can use the software for all areas of the business, from marketing to operational content, so we are now looking to use the software in other areas of the business
It did take a little time to learn the software and i would have liked to have my own image as the avatar .. however over all it works well for us, and we intend to continue to use it
its giving us a nother avenue to market the business
They have the best lipsync quality among all the services available in the market, the last avatars are good looking and a little more modern and updated.
In general the avatars are outdated and non sense. They create many voices in USA english, but only a few for other languages. In a world so diverse like today, they should include avatars that could express this multitude of cultures and languages.
When it is urgent to create a video and you have no actors, no place to record, you can consider to use Synthesia, but just for a few use cases right now; but is a valid and cheap solution.
-A i. Avatars -good Speech ability -user-friendly interface
Compared to application like powtoon or clipchamp, except for the Ai avatars add , the Synthesia application is still far from that level
Synthesia saves time and money for presentation , so it creates an added value to my presentation and is quite fast when you are used to work with different suites
It is nice to reduce the consumption of time to produce videos. It is also helpful into e-learning course developement.
Find voice pitch problem, lip sing not match, find joint of neck in mostly avatars, repetition of body posters.
It can be more useful to develop elearning content. Easy to develop training sessions.
Ease of use and the quality of the videos that are produced. Ability to customize and translate.
I still need to understand how to use the SW best.
How to communicate better? Still experimenting with the software, especially how to make a step change.
I like the ease of use, and realism/appearance of the avatars - especially the lip-sync capabilities.
I think there need to be more options for voices - especially urban/African/Caribbean tones. I would also like to see more clothing options for the avatars. There is an inconsistency in the accuracy of the audio - post rendering. I have experienced drastic changes compared to when I previewed the audio.
It has helped me to be more creative, but I wish there were more options to customise the avatars. I'm sure that's not a good business move on your part, but many of my clients simply can't afford a custom avatar at that price. Maybe offer a higher tier for advanced customisation???
The fact that you can create a video in multiple languages and change it in a sec after you found a mistake or the information changed is a breeze. We stopped hassling around with making videos, having to take care of background, lighting, multiple runs, editing, etc. This is our way to go now, and we have already had clients wanting to use it for their own business.
Mass generation of videos can be improved; we'd like to create millions per day, all personalized, but that's not an option yet. I know it'll come though; they've been adding new features very regularly.
Making videos and updating videos in multiple languages is a breeze now. That saves time and money and offers flexibility.
The avatars are good and diverse enough.
The desktop version for everything including billing
