😲 Deepfake Technology and Meta Humans

The speaker discusses the resurgence of interest in deepfake technology due to recent viral videos featuring meta humans. They mention that they used to create deepfake tutorials and have been asked for their opinion on the current trend. The video will show the tool being used, which is called DeepFaceLive, created by iprof, a Russian developer known for DeepFaceLab. The speaker advises caution when downloading and using such tools due to potential privacy concerns. They guide viewers on how to install DeepFaceLive and use it with pre-trained faces or by training it with new ones. The video also demonstrates how to use the tool with a live stream and a pre-recorded video of a metahuman, highlighting the limitations of the technology, especially in close-ups where the deepfake effect can become apparent.

🎭 Limitations and Potential Uses of Deepfake

The speaker elaborates on the limitations of using deepfake technology for animating meta humans, noting that while the models look good when static, they fail to convincingly mimic realistic facial movements, such as blinking or speaking, which can easily reveal the artificiality. They express a desire for future tools that can utilize deep learning to improve facial animation realism. Despite these limitations, the speaker suggests potential fun uses for the technology, such as pranking during video calls by superimposing one's face with that of a celebrity or character. The speaker concludes by inviting viewers to share their thoughts on the technology and expresses hope for advancements that could make deepfake more useful for animation and other applications.

Keywords

💡Deepfake

Deepfake refers to a technology that uses artificial intelligence to create realistic but fake videos or audios by superimposing existing images and voices onto source images or videos. In the context of the video, deepfakes are used to replace the faces of individuals with those of celebrities or other people, creating a 'deepfake' video. The script mentions that the tool 'Deep Face Lab' is used for creating these deepfakes.

💡Metahuman

Metahuman is a term used to describe highly realistic digital human characters, often used in video games, films, and other media. These characters are created using advanced 3D modeling and animation techniques. The video discusses the use of Metahumans in conjunction with deepfake technology to create realistic facial animations.

💡Deep Face Lab

Deep Face Lab is a software tool mentioned in the script that is used for creating deepfake videos. It allows users to train the software on a specific face and then use it to replace faces in videos. The script explains that the creator of Deep Face Lab has also developed a new tool called 'Deep Face Live' for live streaming deepfakes.

💡Pre-trained faces

In the context of the video, pre-trained faces refer to digital models of faces that have already been processed and trained by the software to be used in deepfake applications. The script mentions that 'Deep Face Live' comes with seven pre-trained faces, including those of well-known individuals like Elon Musk and Jim Carrey.
