You could export a video file like we just saw in the previous chapter, or you could use Loti, a free library that renders After Effect animation into code. With Loti, you can export your animation into a single.json file that can then be integrated into any website. This is way better than using a video file because it's less heavy and loads really quickly. Let's take this animation for example. Exported as a video it weighs about 3.5 megs. But as a json file created with Loti it's only about 250 kilobytes. That's a pretty big difference. And if you have a lot of animation on your website, it can add up really fast. And even more importantly, it keeps all your shapes in vector format. That means that your animation will be perfectly crisp on all resolution and devices. And since all the elements are in vector format, the developers can actually change their color and change the color of the background, just like they could with a SVG file. Another reason why Loti is so useful is that the developers can control the speed of the animation. They can make it play at the intended speed, but they can also speed it up, or slow it down, and the animation will stay at the same frame rate. So it won't look jumpy even if you're slowing it down by a lot, unlike with a video. The developers can also decide which keyframe to play. So let's say you have an animation with different steps inside. You could decide to animate the first step when you arrive on the website, then animate the second step only when you reach a certain point in the page, and then the third and the fourth. You could also decide to reverse the animation to make it disappear at the bottom of the page. All of that in one single file that weighs less than a meg. This is so useful because the developers no longer need to write thousands of lines of hard to maintain code. Now, as a designer, you can do it way faster directly in After Effects. It also gives you the bragging right to say that you coded part of the website by yourself.",
