Compare Synthesia with other popular tools in the same category.
Lipsync for text to video, easa uf use. Great Customer Support.
There is an opportunity to step up when it comes to equallity of dB levels of the generated mp4 files, as well as resolution (4K please!-). Clothing style of Avatars does not reflect a global audience.
Transforming boring PowerPoint files to exciting Explainer movies.
It is Simplicity itself and very ease of use
The occasional mispronunciation of english written words, you have to spell them phonetically to get the avater to pronounce correctly.
video production
Chance to use avatars in explanations Less "cold" experience for users
Should be able to make presentation with similar tools as Power Ponit, is tough to use some tools, and dont have same amount of tool as Power Ponit
Training use
Synthesia is akin to Powerpoint in some ways. Due to this similarity with a popular tool, the learning curve of Synthesia is relatively fast. The numerous training videos are a treat for customers wanting to learn Synthesia and take great videos using their tips and tricks. It is an excellent tool for quick video production without the hassle of "green screen, cameras, voice-over actors and a litany of other props."
The limited number of video minutes per month is a constraint. If they can allow the purchase of additional minutes and, more importantly, allow the carryover of unused minutes, the tool will become much more usable.
It allows us to produce product videos rapidly without needing external skills. Even a non-creative person can create a decent video. We have done a few videos now and it is super easy.
The language options are really important. Yes, the avatars are also good and a secent number of them have been presented.
The voice could have been more natural sounding, specially the propunciation of some Indian words.
Creating cost effective videos with avatars was always a challenge.
I love how Synthesia allows you or your team to create uniform videos that can be altered quickly by just changing the script.
The biggest downside is bandwidth. Sometimes you have to reload during creation or wait for content to process.
Uniform professional videos and eventually a quick way to convert videos to multiple languages.
I like the fact that it is very rapid to use, and also intuitive. Moreover, in cases of questions it is very easy to ask for help and receive a very rapid ans usually very usefull feedback.
I find that it could be helpful to be also able to export synthesia as a pptx format. Moreover, a lot of the photos and animations in the library are not usable because they have a writing on it. Lastly, an additional helpful feature would be to more easily be able to download content from other apps, for instance in order to create a cartoon video etc...
It helps me to create very intuitive and well explained tutorials, thanks to the diverse voices of the avatars that are particularly realistic.
High quality, great templates, fantastic support
Would prefer if the mouths of the avatars more closely aligned with the voice
Personalized customer marketing videos
The most helpful aspect of Synthesia was the easy-to-use layout. I was able to create realistic avatar videos in multiple languages in record time! Compared to competitors, it exceeded my expectations in terms of ease of use as well as realism in different languages.
The downside of Synthesia was the sometimes unpredictable time to generate videos. Overall, however, it was still relatively quick (within minutes). Possible improvements would include more avatars and more voicing options.
Synthesia is helping me solve the problem of low user engagement and helping to increase active participation.
Time saving Templates and design Ergonomy
Robot tone speaking in french some avatar's expressions possibility
Time saving
simplicity and ease of use number of avatars
- lack of African accents in French (West Africa) - impossible to make a simple video with avatar and transparent background
lack of video creation and editing skills
The best about Synthesia? It is particularly easy to use
The dislike about Synthesia? often the background image does not fit well
it helps me to easily create many videos in a short time and on a small budget
I loved the ease of use, the intuitive user interface and how simple the task of making a quick edit is. The processing time is fast and efficient, and the voice selections are very good. Some of the obviously older voices are a little robotic in their sound and diction, but overall, most of the english speaking voices are great!
We have an extensive list of distributors located throughout the world including but not limited to Europe, Asia, and the Middle East. We made a test video in French, German, Italian, Spanish, and Korean. The feedback from Korea was that the language used in the video was not Korean but a "jumbled language." French and Italian feedback was similar. The AI algorythms will need to be adjusted and refined. Would not recommend using any other language than the native language the script is written in.
Synthesia solves the need for a "talking head" for quick marketing and trainign content we want to produce to promote our products. A few more medical professional looking Avatars would be great for us!
The best thing about Synthesia is how user-friendly it can be. The avatars are realistic and natural-looking. It also allows for a variety of video presentations. I've had a couple of questions that were readily answered by the Synthesia support team which is a big plus.
The one area of improvement that I would love to see Cynthia and Jet take on is the ability to use more than one avatar in AC. Right now, you are limited to individual presentations. You can switch up the different avatars with each new scene but, you just cannot have two or three avatars speaking within the same scene. I am sure this is something the team at Synthesia is working on and hopefully the Beta will be available soon. There is nothing that I dislike as the support has been excellent and other than the issue above, I don't see any other negative feelings about the product.
In my business, social media, marketing is important, and video. Presentations are much more engaging than static photos. Since I am not the best on screen, I find working with this AI platform to be a huge boost to my lead development with my social media ads. In addition, I've been able to add variety to my presentations by putting in AI components with avatars as an interesting change of pace from when I was presenting at an event.
Variety of AI voices, ease of use, custom avatar (with a yearly subscription), and reasonable pricing.
More avatars would be better. Also, undo-redo operations are a bit clumsy but gets fixed with a refresh.
I don't need to hire a video artist to create content anymore.
Gets the job done. Overall a good experience
Sometimes difficult to navigate. Could be simpler
Support videos
The AI avatars look so natural. The templates makes our job easy. Most importantly the UI to looks clean and easy!
The only things is to find out the remaining minutes on the account, so that we can plan the video accordingly
We dont have to spend money on expensive video shooting apart from that we can control the dialogue delivery
Synthesia lets you generate training videos quickly and update them without having to start from scratch. The ability to create your own avatar is a very welcome addition.
The choice of avatars could be improved, but the possibility of creating your own avatar makes up for this lack of choice.
Synthesia allows me to generate training videos very quickly, and to update them even faster.
The thing I found most useful is the content generation and voice generation tool
Limited creation of backgrounds or videos appropriate to the content
Limited creation of backgrounds or videos appropriate to the content & Limitation of creating content in Arabic with proper language
The innovative concept and ease of use of the platform to create videos.
Poor lip sinc with avatars creating an artificial feel.
Synthesia is a great way to personalize videos. It speeds up the process of creating videos is much more affordable than doing it manually.
the customer support responds very quickly
no clear indication of how many credits you have available (the customer support can provide you this info but still not satisfying - no details)
no need to stand in front of the camera saves me time makes it look professional i am more productive
I can easily create videos for my How-To content. Dsahboard is nice
I cannot make Thumbnails for videos, Synthesia should give an option to create thumbnails of these AI avatars
Quite efficient and fast to make videos, i dont have studio at office but still can make good videos through AI avatars.
Making 'real life looking' avatars doing basic demonstrations is a breeze. The avatars that move a bit is very effective. I guess things will improve regarding the avatars being programmed to look in various directions, like at another avatar in conversation (hint!).
Contacting Synthesia's sales team to obtain corporate pricing. Their web automation is great, fast, reliable and can get a small presentation downloaded in minutes – this to me offsets the human factor which took almost a month to reply with basic pricing.
Saving production time.
I'm a teacher in a university and also need to create manuals and instructions and the use of Synthesia is helping me a lot to produce nice material and saving a lot of time
I'm a powerpoint and Goggle Slides user and the editing functions are much easier to use, I would like a manner to edit the slides in a faster way as I do with the mentioned tools we normally use for presentations
I need to produce classes and some of the material needed to be recorded as live lessons, with synthesia I don't need to care about my narratives and I also can use cool avatars that people likes a lot
I like that Synthesia has multiple avatars and are constantly adding new avatars. Even better is that they are adding some of the same avatars with different clothing options to use based on the topic and audience of the video.
The lip sync needs to be improved in some cases. Some of the actors/avatars need a lot of improvement. However, I don't think there is a single avatar that is perfect with the lipsync. I think that the actors need to do a better job of lip formation when they are reading the script while being filmed (certain consonants don't have appropriate lip formation).
Our biggest problem was coordinating schedules with our live talent to be able to be filmed in the studio...especially because many of the live talent didn't want to be videotaped and they would never make themselves available. Now, with Synthesia, we can have a "person" speaking to the audience whenever we need to create a video and not have to coordinate schedules.
Synthesia has made creating training videos so easy, before we would need to record ourselves, edit and export the footage, and whenever we needed to update the content we would have to repeat the whole process. Synthesia has saved us so much time, being able to edit the script and re-export our videos has been amazing.
When updating content, it would make life much easier if I could re-import powerpoint slides whilst editing a video. You can import slides when you first create a video, but I can't see a way to update these slides other than starting a new video.
Has saved me lots of time which I can dedicate to other areas, I used to need to re-edit and re-export videos when I changed the talk track in any of our videos, however now I can just edit the script and re-export. So much faster.
The plug and play principle. You just need to have your idea set and the outcome is simply as realistic as it can be. It is easy to use and user friendly. It is unbeatable.
Some avatar and their voices does not look and sound very realistic or simply human. I do believe that Synthesia has reach a major leap forward, but there are some room for improvement.
It solves the challenge of creating videos fast, with minimum resources and as realistic and human like as possible. The delivery is faster than any other service currently available.
The script options are quite vast with all the languages options
The animations and adding elements are bit diffficulta and quite limited
The problem of having to hire a photographer and and model to promote our brand
The Speed of making videos is fast and I love just inputting the script and the host does lines perfectly 1st time around.
does not have transitions from scene to scene
Lipsync with the avatars and speech speed with the avatars it is helping me bring text pages to life in video. great for marketing and doing social media I LIKE VERY MUCH
I don't need a green screen or studio gear! :)
Lags quite a bit and does not offer enough exports for the $270 a year price.
I do not have to record 100 takes; I simply update the script!
