Premiere is a computer program that helps people make videos. It's like a special tool that makes it easy to put together different parts of a video, like clips of people talking or doing things, music, sound effects and pictures.
You can use the tools in Premiere to edit the video by making parts longer or shorter, cutting things out or adding things in. You can also change the colors and brightness of the video, make it look like it's moving in slow motion or fast motion and add text to help people understand what's going on in the video.
Once you're finished editing your video in Premiere, you can then share it with other people by saving it as a file or uploading it to a website like YouTube. People all around the world can watch the video you made and they might even think it's really cool!
