A minimum of 25 fps is recommended for video, but at Creatomate, we render our videos at 60 fps for smoother animations. The lower the FPS, the more jerky the video will be. In video, we talk about frames per second as a measure of how many images are displayed every second. When we think about it, a video is nothing more than a series of images displayed in quick succession. Rather than making a still image, let's make a video with motion. The last step is to make an image file from the canvas and save it to disk: Next, we load assets/logo.svg and draw it at position x=100 and y=100 with dimensions 500 by 500. The context object gives us the interface for drawing on the canvas. Imagine it as a blank sheet of paper 1280 by 720 pixels wide, on which we can draw pictures, shapes, and texts. To begin with, we'll create a new Canvas instance. Let's start from the beginning by drawing a single frame first. Following these basic concepts, we will introduce easing, keyframes, drawing contexts, and transformations. In this step, we'll create a simple video with only a single element, just to go over the basics of video rendering. They want to create these videos in thousands, so we're going to build an application for them to render these custom videos in bulk. Let's say we're developing an application for a travel agency, which is looking to generate custom videos tailored to various travel destinations. In this tutorial, you'll learn how to accomplish this using pure JavaScript and Node.js, along with the help of FFmpeg for the encoding. The best part is that all of this can be done with open source software and without using C++ or any other low-level language. Wouldn't it be great if we could automate the creation of these videos programmatically, using something like a video template and dynamic data? As a matter of fact, this is possible. There is also a growing trend of using video in email campaigns. This is especially true for social media, which has become increasingly video-centric. There is no better way to convey your message than by using video, since it is more engaging and fun than any other medium.
