Discover the world of AI-based videos: basics and opportunities

In this guide, I want to answer the fundamental question for you: What is actually a video? In the age of Artificial Intelligence (AI) and modern media production, it is important to understand the concepts behind videos and their creation. You will see that a video is not much different from a compilation of images and that AI tools are able to generate these images and combine them into a functioning video.

Main Insights

• A video consists of many images that are played sequentially at a certain speed.
• AI can generate these images and create entire videos. The most common unit of measurement is Frames per Second (FPS).
• A better understanding of these basics is key to starting with the creation of videos using AI tools.

Step-by-Step Guide

What is a Video?

At the beginning, it is important to clarify what a video actually is. A video typically consists of a rapid sequence of images that are played at a certain speed. For example, when you hear "30 FPS", it means that 30 images are overlaid per second. So, when you watch a video recorded at 30 FPS, you are actually seeing 30 images shown in quick succession. This principle ensures that the movements in the video appear fluid.

How Does Video Creation with AI Work?

With today's technology, it is possible for AI to create entire videos. Essentially, if an AI can generate a single image, it can also produce many images sequentially to generate a complete video. This means that with the right tools, you can create a video based on a text description or existing images.

The Role of Frames

The quality of a video largely depends on the number of frames used. High-quality videos often use 60 FPS, resulting in smoother playback than the commonly used 30 FPS. If AI is able to generate many frames per second, it can deliver a high-quality video. It is important to understand these connections as they are crucial for how your own AI-generated videos will appear later on.

The Underlying Technology

A crucial element in AI video creation is the technology of diffusion models. Diffusion models can perform a variety of tasks, including creating "Deep Fakes" or transforming an image into a video and vice versa. All these processes work because we are able to recreate or transform each individual frame of a video.

Challenges in Image Creation

However, there are also some challenges when it comes to creating consistent images. A common problem is that it can be difficult to depict a character who looks the same in different environments. To achieve this, techniques and tools for support must be used, such as working with "LoRAs" specifically developed for diffusion models. But don't worry, in this guide, you will learn how to effectively utilize these technologies.

How AI Can Create Videos from Text

Now it gets exciting: AI can not only generate videos from images but also directly from textual descriptions. This means that you can start with a clear text instruction and have the AI generate the corresponding images to create a cohesive video. The use of such tools can significantly enhance creativity and efficiency in video production.

Next Steps and Further Learning Opportunities

In this course, we will take a closer look at the various tools and techniques that enable you to create AI-generated videos. One important aspect will be understanding and applying a diffusion model correctly. Once you are familiar with these fundamentals, you will find it much easier in the following lessons to turn your ideas into impressive videos.

Summary - Creating AI Videos: Basics and Functionality

In this guide, you have learned that videos consist of many individual frames and that Artificial Intelligence is capable of generating these frames. With a better understanding of the technology and fundamentals, you will be able to produce your own creative video content.
