ELI5: how does HeyGen work

HeyGen works like a magical puppet show where you can change the puppet's words without re-recording the whole show.

Imagine you have a favorite toy puppet. Normally, if you wanted the puppet to say something different, you'd have to record a new video of the puppet saying new lines. HeyGen is like a super-smart puppet master that can make the puppet say new words without needing a whole new video!

Here's how it works:

• First, you give HeyGen a video of your puppet (or yourself!) talking. This is like showing the puppet master what the puppet looks like and how it moves its mouth when it talks.

• Then, you type in the new words you want the puppet to say. This is like writing a new script for the puppet show.

• HeyGen then uses a special computer brain (called Artificial Intelligence or AI) to figure out how to make the puppet's mouth move to match the new words. Think of it like the puppet master carefully adjusting the puppet's strings to make it look like it's really saying those words. It looks at the original video to learn how your face moves and then makes the changes.

• Finally, HeyGen creates a new video where the puppet is saying the new words, even though you never recorded it saying them! It's like magic! The puppet show is updated without having to start from scratch.
