How does AI Video Generation work to?

Video content used to be inaccessible to budget marketers due to its high production costs and technical expertise requirements. But now with the AI takeover, this barrier has been shattered. Now, with AI, you can create stunning video visuals with something as simple as a text prompt, and this is a greatly welcomed development. But what happens behind the screens of an AI video generator? How does AI video generation work?

How can an AI video generator create a masterpiece with just a bit of text? If you are curious, then stick around because we are going to unpack it brick by brick in this blog.

What Are AI Video Generators?

AI video generators are advanced technology tools that turn your texts into visually stunning videos. But how does it do it? It uses Natural Language Processing (NLP) to understand text prompts, find semantics, and then match them with its existing visual library to make a video.

Well, that is the brief overview of it. But don’t worry, let us simplify it more so we can figure out how it works exactly.

How does AI video generation work?

The input that you give these generators generally goes through layers of processing before it becomes the video that you get to publish. Let’s see what exactly happens in this instance.

1. Analyse Input

The AI video generator model first receives the text input that you give it. Then it uses Natural Language Processing (NLP) to understand the underlying meaning, sentiments, and semantic value of the message.

Once the system has an understanding of the user’s requirements through the input, it now converts the message into machine-readable vectors. These vectors are then used in subsequent steps to generate the video.

2. Generating scenes and composing visuals

The next step after understanding the message is to come up with a screenplay. The core message behind scenes and visuals needs to be finalised. These visuals can be anything from ones that are retrieved from existing visual libraries, stock images, or generated from scratch.

Generative AI models like Stable Diffusion or transformer models carry this part of the process.

3. Adding Voice to the Video

The next main part that needs to be tackled in a video creation process is adding the voice and audio to the video. But AI models have evolved from doing robot-like narrations and can now inflict emotions, have inflections, and even pause between speech like a human.

AI models like neural TTS (Text-to-Speech) and SSML (Speech Synthesis Markup Language) play a major part in getting this done.

If your video has avatar or human-like presenters in it, then by using viseme prediction, you can even make them lip-sync accurately to the audio.

These AI avatars can even be programmed to behave like humans by giving subtle facial expressions, voice pauses, and body language to match the audio. These small effects are a great step towards making videos more real.

4. Building a coherent video

Now that the technical portions of a video are taken care of individually, it is time to assemble them. And the first step to assembling it is to establish a timeline from start to end.

Once AI uses its logic to have a sequence of scenes to follow through, it then matches the scenes with the right text, voiceover, avatar, and so on. Transitions and overlays are placed strategically to ensure the video is understandable and natural.

5. Rendering the Final Product

Once every element is in place, the final video is made ready. With GPU-accelerated processing, the text, video, and audio elements are stitched together. Then compression tools are used to reduce the file size of the video without compromising the quality, even if you choose to download it in 1080 or 4K.

Based on how complex your prompt was, how long the final product is, and what your desired output format is, the rendering time can be different. Sometimes, it can even take up to hours to get it done.

5 Top Uses of AI Video Generators

Now that we know how does AI video generation work, next we have to see what its uses are. AI video generators greatly reduce the amount of time and resources it takes to make a video from scratch. So, any business or organisation that requires lots of videos to be generated can greatly benefit from AI video generators.

1. Repurposing Content

Repurposing content helps put the limelight on content that performed well in the past. If a blog of yours is performing well and you would like to convert that into a video, then AI video generators can do it for you in a hassle-free manner. 

2. Corporate Training Videos

Training employees requires a lot of time and resources, but with videos, this process can be made less painful. And, videos are easier to understand and more engaging than documentation. But if you want to make many modules, then the production cost can be high. In such cases, AI video generators can come in handy since they can produce high-quality content in less time and budget.

3. Social media content

Social media has become the primary tool for marketers around the world. This has made brands put significant efforts into maintaining their online presence. But managing many platforms, planning content, and posting consistently on top of running a business can be outright daunting. Taking the help of AI video generators can simplify the process immensely.

4. Online courses

Online courses have helped people learn skills from the comfort of their own homes. This is why most people prefer to learn things online. However, creating such online videos can require the creator to have video equipment and resources, which they otherwise might not have. By using AI video ad generators, the creators can make their video production easy and focus instead on curriculum development.

5. Marketing videos

Having demo videos in the landing pages and product videos in product pages has become the norm these days. Making these videos can be outsourced to AI to avoid the repetitive process and streamline the content creation process.
