A YouTube video creator

This is an idea for this app that I had a long time ago. The app would allow you to create a customised video with the following features:<br><br>1. You have an audio clip of someone saying a sentence, eg<br>> David Attenborough:<br>> “We are now on the hunt for the most valuable treasure in the forest”<br><br>2. You could choose an animation of a cartoon character, eg<br>> A monkey running<br><br>3. You could choose a background video (or animation), eg<br>> A forest<br><br>4. You could choose a theme for the video, eg<br>> Treasure hunt<br><br>5. The app would replace the audio of the background video with the audio clip.<br><br>6. The app would fit the animation of the monkey to the audio clip, so that the monkey runs to the beat of the audio and if the audio clip had a slight echo or reverb the movement of the monkey could be similar. The app would work on getting the monkey to move in sync with the sound effects of the background audio.<br><br>7. The app would change the animation of the monkey to fit the theme and background of the video. For example, the app could add leaves and twigs to the monkey animation and make the monkey change direction when it hits a tree.<br><br>8. The app would have a feature to add more features to the video, like before the monkey starts running, a treasure chest flies into the screen and lands somewhere random on the background.<br><br>9. The app would have a feature to change to a different theme. So maybe you could change the theme from a treasure hunt to a BBQ and the monkey would now be wearing sunglasses and the background could change to a beach. The app would make the treasure chest change to a picnic basket and things like that.<br><br>10. The app could also be used as a game, where you can control any of the animations on screen and the app would use AI to change the behaviours of the other animations in relation to the animations that you were controlling. Or you could control a character in the video and the app would change the behaviours of the other animations in relation to the controls that you are doing.
