While deepfakes essentially means creating synthetic videos with deep neural networks, the colloquial use of the term is for transferring movements and expressions of one person to another; an equivalent in the real-world would be voice mimicking for speech.
At Rephrase.ai, we create real videos from scratch. What traditionally used to take a team of director, camera people, actors, sound engineers, costume designers days to create your perfect video, we create the same beautiful video in real-time with the help of Rephrase engine which is completely driven by software! A team of tech-savvy and responsible humans are teaching the software to become better everyday while learning how to do the same on their own.
The basis for our platform is facial re-enactment, where we predict the lip movements, facial expressions, head movements, eye blinks, and everything that goes into making the AI-driven presenter's face look photorealistic.
To conclude, while both technologies are very powerful, deepfakes have gained a bad reputation because of its use for iniquitous purposes (politics, pornography etc.)
