I tried the free version, and it did as advertised. On the basis of its representation that the pay version unlocks 4k video, I paid for the real-time deepfake. The quality is still poor, especially around the eyes and mouth. I used a high-res photo to deepfake a high-res video clip. The result was a working deepfake, but of sub-par quality. The look was rough. I run this on an iPhone 14 Pro Max. Hardware isn’t the issue. Other apps offer much sharper face swapping but with some limitations. I’m going to pass on the one time, forever unlock of unlimited video. If the quality of RealDeep improves, I would reconsider. Also, it would be nice if there were an option to hide the UI.
