In blogs i talk what is Deepfakes and why is very important and dangerous
What is Deepfake
Deepfakes (portmanteau of “deep learning” and “fake”) are synthetic media that have been digitally manipulated to replace one person’s likeness convincingly with that of another. Deepfakes are the manipulation of facial appearance through deep generative methods. While the act of creating fake content is not new, deepfakes leverage powerful techniques from machine learning and artificial intelligence to manipulate or generate visual and audio content that can more easily deceive. The main machine learning methods used to create deepfakes are based on deep learning and involve training generative neural network architectures, such as autoencoders, or generative adversarial networks (GANs). In turn the field of image forensics develops techniques to detect manipulated images.
Deepfakes have garnered widespread attention for their potential use in creating child sexual abuse material, celebrity pornographic videos, revenge porn, fake news, hoaxes, bullying, and financial fraud. The spreading of disinformation and hate speech through deepfakes has a potential to undermine core functions and norms of democratic systems by interfering with people’s ability to participate in decisions that affect them, determine collective agendas and express political will through informed decision-making.This has elicited responses from both industry and government to detect and limit their use.
From traditional entertainment to gaming, deepfake technology has evolved to be increasingly convincing and available to the public, allowing the disruption of the entertainment and media industries. And A deepfake is a video, photo, or audio recording that seems real but has been manipulated with artificial intelligence technologies. Deepfakes are usually pornographic and disproportionately victimize women. However, deepfakes can also be used to influence elections or incite civil unrest.
Anyone with basic computing skills and a home computer can create a deepfake. Some methods to detect deepfakes use AI to analyze videos for details that deepfakes fail to imitate realistically — such as blinking or facial tics.
However, detection is challenging because deepfake technologies evolve rapidly.
Potential errors in deepfakes
And how deepfake work
Deepfake videos commonly swap faces or manipulate facial expressions. The image below illustrates how this is done. In face swapping, the face on the left is placed on another person’s body. In facial manipulation, the expressions of the face on the left are imitated by the face on the right.
Face Swapping and Facial Manipulation
How can you spot a deepfake?
The figure below illustrates some of the ways you can identify a deepfake from the real thing. To learn more about how to identify a deepfake, and to learn about the underlying technology used, check out our recent A deepfake is a video, photo, or audio recording that seems real but has been manipulated with artificial intelligence technologies.

And now you know What is Deepfake and how it work Now you know how to use sadtalker to make deepfake video and now you have question what is sadtalker sadtalker is tools to make video by use deepfake but in now 2023 it have a many deepfake tools is did is not Dissociative Identity Disorder but it is tools to make video by use deepfake but did is use money to pay but sadtalker is free don’t pay money but install by github And how sadtalker work SadTalker Face Animation with AI is a tool that can make faces move using voice audio. It gives amazing results and is easy to set up with my guide. It uses Stable Diffusion to create animated faces. You can use either text-to-speech or actual voice recordings as input for the animation.
Ok now you know what is sadtalker now we will install and use let’s go
first one go to repository sadtalker from github
next step install sadtalker for linux
git clone https://github.com/OpenTalker/SadTalker.gitcd SadTalker
conda create -n sadtalker python=3.8
conda activate sadtalker
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu113
conda install ffmpeg
pip install -r requirements.txt
### Coqui TTS is optional for gradio demo.
### pip install TTS
nextstep install model by this commands
bash scripts/download_models.sh
run this script to donwload model from model repository
next step start webui by this commands
python3 launcher.py or this commands ./webui.sh
run by python3
python3 launcher.py
./webui.sh #run whit ./webui.sh
here this result
next step select image from directory examples/source_image to paste in Upload image but if you don’t like image in examples folder you can create your own image by use stable-diffusion from this repo https://github.com/AUTOMATIC1111/stable-diffusion-webui.git to create you own image and paste in examples/source_image but i use basic image in examples/source_image to teach you
next step select wav file from directory examples/driven_audio to paste in Upload or tts but if you don’t like wav file in examples/driven_audio folder you can create your own wav file by use this app in linux is https://flathub.org/apps/org.gnome.SoundRecorder to recoding your voice to use in this tools but i use my wav file from anthor repo but it live in examples/driven_audio
here this is result
in the face model resolution i recoment to select 512 but if you have a less memory gpu like me select 256 and in the preprocess i recoment to select full and batch size in generation you can select a lot more than 2 if you have a more memory of gpu ram but i select 3 because i have gpu memory 4 in gtx 1050 ok if you select all every thing ready click Generate now and watch the result
here this is result but this result is have underfiting but if you need to know what is underfiting checkout this blogs https://medium.com/gopenai/what-is-underfitting-overfitting-and-how-to-solve-2-issues-275b9933cd29
now you know what is deepfake and learn to you tools i hope you like my blogs thanks for read

As Andrew Ng put it: “Just as electricity transformed almost everything 100 years ago, today I actually have a hard time thinking of an industry that I don’t think AI will transform in the next several years.”
However, bad actors can misuse AI easily. Let’s look at an application of AI that’s been used to trick people and spread misinformation: AI-generated images, some of which we call deepfakes.
