[0:04]Imagine seeing a video of a famous person saying something shocking or watching yourself do something cool that you never actually did.
[0:11]It might look real, but here's the thing: it could be a deep fake created by AI.
[0:18]But what exactly is a deep fake and how does AI make it happen?
[0:24]Let's find out. A deep fake is a video or image that's been altered or completely made by AI to look like something it's not.
[0:30]AI can take real photos or videos and change them to show something or someone else doing or saying things they never did.
[0:39]The word deep fake comes from deep learning, which is a type of AI that learns from tons of data, like pictures and videos, and fake because it's not real.
[0:50]So, how does AI create these fake videos and images?
[0:54]It all starts with machine learning. AI looks at a huge amount of data, like hundreds of pictures or videos of a person's face and learns how they look from every angle.
[1:05]Once the AI knows what someone looks like, it can use that information to create a new video or image that seems completely real.
[1:15]For example, AI can take a video of someone talking and replace their face with someone else's, making it look like the second person is saying those words.
[1:23]And because the AI has learned so much about how faces move, blink, and smile, it can make the deep fake look incredibly realistic.
[1:32]Deep fakes can be fun and used in cool ways, like putting yourself in a movie or creating a funny video with your friends.
[1:39]But they can also be dangerous.
[1:43]Imagine if someone used a deep fake to make it look like a famous person said something they didn't or to spread false information.
[1:49]That's where things get tricky, and it raises some important questions about trust and ethics.
[1:58]Because deep fakes look so real, it's getting harder to tell what's true and what's fake.
[2:02]This is why researchers and tech companies are working on ways to spot deep fakes, using AI to fight AI.
[2:09]They're creating tools to help people identify fake videos and photos so we can stop misinformation from spreading.
[2:17]So, while deep fakes are a fascinating use of AI, it's important to be careful and think critically about what we see online.
[2:24]Remember, just because something looks real, doesn't mean it always is.
[2:30]AI is powerful, but with great power comes great responsibility.
