That’s pretty impressive, but it’s easier to fool our brain’s “human detector” for just a still photo. Photorealistic 3d models are still a bit “off”, but they are getting much better. I have been playing around with Unreal Engine 5 and the Metahumans creator, which makes very high quality photorealistic 3d models, but you can still easily notice they are not real humans, even at the highest rendering quality.
What is nice is that the rendering is done on Unreal’s servers, so you do not need a rack of computers dedicated to rendering to play around with this. You just design what you want on their website, then let them render it and download the result. And it’s free.
Do these apps build the images from scratch, or do they start with actual photos of real people and then modify them in some way?
