 Hello everybody welcome back to another After Effects tutorial on this one I'm going to show you how to pixelate or blur something or somebody in a video. Here's the original footage of a couple running and then presto I added in a blur or a pixelation and I also only applied it to the half of the video that she's on so you can obviously use masking. How did I do this? Let me show you step by step it'll take 60 seconds. Stay with me so we're going to delete that footage and presto we've got this couple running. The next step this is not necessary but I'm going to do it to show you the effect edit duplicate so we've got two versions of them on top of each other. I'm going to turn the bottom one off and we're going to work on the top level. The next step go to your effects and presets panel and type in ball action I know I know ball action no joke apply that to the top layer like I've done that. If I zoom in here you're going to see that there is a slight pixelation effect or a mosaic type look excellent but we're not quite where we want to be what you want to do next is simply increase the grid spacing that's it now we've got a pixelated or blurred pixelated look now if we just wanted to blur the lady out for example we can just go up here to our little rectangle tool grab the rectangle tool and just watch presto we've grid we've blurred her out and because we've got a second layer underneath the left side will now appear and boom there you go
