As a month later, a neural network is used to impose celebrity faces on porn actresses

The application simplified the creation of commercials and led to dozens of examples on Reddit. But some users are trying to go beyond porn.

In December 2017, the network appeared fake pornographers with Gal Gadot, Emma Watson and Macy Williams. The user Reddit under the nickname deepfakes “transferred” their faces to already existing frank videos from porn sites, using the open algorithms of machine learning. About these videos for the first time in detail told the journalist Motherboard Samantha Cole (Samantha Cole), raising the issue of the ethics of technology.

A month later, she studied how the situation changed with the “painting” of faces on Reddit, and was convinced that the creation of fake pornographers was now “being done by everyone”.  chose the main conclusions from her material.

There were a lot of videos

Cole counted on Reddit dozens of new videos with popular actresses and singers, although even in December there were 5-6 of them. This is due to the advent of the FakeApp application: a tool with a neural network of deepfakes in the base, allowing people to change faces on the video even to users without programming skills and not familiar with machine learning. In January 2018 came out the desktop version of the program for everyone.

On Reddit, the users of the application have teamed up on sabreddita r / deepfakes , where they share videos and tips for beginners. The journalist Motherboard noted that the community is developing with “appalling speed”. Over a month, it was signed by more than 18 thousand people. And online there were pornographers with faces set by Daisy Ridley, Katy Perry, Natalie Portman, Jessica Alba, Natalie Dormer and other famous actresses.

Samantha Cole said that some videos became difficult to distinguish from reality. If in previous versions of the neural network, along with the “painted” face, you could see a frame that reduced the realism, then in a new application you can get rid of it almost completely. In January, one of the fake videos with Emma Watson appeared on the site CelebJihad, where all the leaks of intimate photos and video of celebrities gather.

The deepfakes itself, who developed the algorithm, is not involved in creating the program, but actively participates in the life of the sabreddita. He did not answer Motherboard questions.

Not at all it turns out to train neural network

To create your own video, you need to upload photos or celebrity videos into the application, as well as a video to which you want to “transfer” the face. Deepfakes in one of the discussions explained that neural networks need to be trained about 500 frames from different angles: a smaller amount will damage the details, and more will lead to problems with the algorithm.

Often, users use video actresses and singers from various interviews, where their face is clearly visible and is constantly in one light. Also, some community members teach a neural network on a video from Instagram or Snapchaat: they say there are more natural emotions on these videos.

However, to create a fake video using FakeApp, you need a powerful computer. With him, the training takes 10-12 hours, with a budgetary one – about a day. The stages are displayed in the application interface, but users still often complain about wasted time: in half a day they see that the quality “painting” did not work out.

FakeApp interface with an unsuccessful result

Another problem is that two persons must “approach” each other so that the result is more natural. Because of this, Reddit users join together into chats and together search for porn actresses that would resemble celebrities. Then they are collected into one database, which they share with the others. On sabreddite there are already “patterned” porn actresses for Emma Watson or Emilia Clark, who make it possible to achieve the greatest similarity.

Otherwise, the result may be blurry or with a large number of artifacts.

The creator of FakeApp under the nickname deepfakeapp acknowledged that the application still does not solve all the problems associated with training neural networks. But he called the instrument a “good starting point” for further improvements.

I want to improve the application to such an extent that potential users can simply select a video on the computer, download a neural network, select a person from the shared library and substitute it with a click of a button.

Algorithm is used not only for porn

Most of the entries on sabreddi deepfakes are devoted to “painting” porn actresses of celebrity faces. But not everyone uses a neural network just for this. Some users work with FakeApp to replace actors in Hollywood movies or “improve” them.

In 2016, the film “Izgoy Odin” was released, the action of which takes place in the universe of Star Wars. At one point in the picture, the young princess Leia was shown, although at the time of the filming of the actress, Carrie Fisher was 60 years old (she died on December 27, 2016). Leia “rejuvenated” with the help of CGI: Fisher’s face was imposed on the Norwegian actress Ingvild Dale, who played in the scene.

Media criticized this moment for unnaturalness. In January 2018, the user derpfakes tried to “improve” the scene with FakeApp and several hundred photos of “a similar actress.” Reddit noted that the result (from below) turned out to be more natural than that of the special effects studio working on “The Outcast One”.

The user under the nickname Z3ROCOOL22 regularly publishes videos made with FakeApp on sabreddi. None of them are connected with porn: mostly they are scenes from films and videos with politicians. Most of them can not be called qualitative. For example, he tried to “transfer” actor Dwayne “Rock” Johnson to “Terminator 2”, and Donald Trump – to “Thor: Ragnarok.”


Samantha Cole noted that one of the attempts was still realistic: Z3ROCOOL22 connected Argentinean President Mauricio Macri with images of Adolf Hitler from the German film “Bunker”, where he was played by Bruno Ganz.

Deepfakeapp in a conversation with Motherboard expressed the hope that in the future, the technology of machine learning will be used more widely, and tools like FakeApp will make neural networks accessible to “ordinary people.” According to the creator of the application, over time, ordinary users will be able to produce results comparable to the work of large companies to create special effects.

The experts interviewed by Cole agree that although the technology is not new, it has become so accessible for the first time in history. And this can greatly undermine the “whole institute of trust and reliability” of people to any video.
