I use Synthesia to create videos on courses, which has made our work more efficient by eliminating the need for individuals to memorize scripts and speak on camera. I like the feature of creating our own Avatars, as it captures a person's likeness and voice, including their accent and tone. The features added to how avatars pose and the scenarios in which they are placed are impressive. I also enjoy the gestures and outfit creation options in avatar creation. Synthesia's initial setup was very easy to understand, allowing me to quickly get into the flow of working.
It’s easy to use, and it makes it simple to duplicate work I’ve already done. I can create consistent videos without much effort, and the avatars look realistic and work well. I particularly like that when I have a script, it automatically maps text to a slide so I don't have to worry about the text on the screen.
