Film editing is like putting together a puzzle. Imagine you have a big box of puzzle pieces and you want to create a picture. You start by sorting all the pieces out by color and shape. Then, you start putting the pieces together in the right order to make the picture you want.
Film editing is just like this! When a movie is filmed, there are a lot of different pieces that need to be put together to create the final product that you see on screen. There are scenes that were filmed from different angles and takes, audio recordings of dialogue and background noises, and lots of other added visual effects like color correction and CGI.
A film editor takes all of these pieces and puts them together in the correct order to tell the story of the film. Just like arranging puzzle pieces, the editor decides which parts to use and which ones to leave out to create the best version of the movie. They also need to make sure that the movie flows well, so that you don't get confused or bored while watching it.
Overall, film editing is a really important part of creating a movie. Without it, there would be no way to take all the different pieces of footage and audio and turn it into a cohesive story that entertains and moves audiences.
