How to Make AI Videos for TikTok

AI-generated videos are taking over TikTok feeds, and you can start creating them faster than you might think. From talking historical figures to mesmerizing animations, creators are using artificial intelligence to produce viral content without giant budgets or complex software. This guide breaks down exactly how to make AI videos for TikTok, guiding you through the best tools, a step-by-step workflow, and strategies to help your content get noticed.

Why AI Videos are Perfect for TikTok

Before jumping into the "how-to," it helps to understand why AI-powered content is such a great fit for the platform. TikTok's algorithm rewards novelty, consistency, and engagement. AI video creation taps into all three of these pillars.

• Speed and Efficiency: Let’s be honest, video production is time-consuming. AI tools can condense hours of work into minutes. You can go from a single idea to a fully scripted, voiced, and animated video in under an hour, making it possible to post new content daily.
• Limitless Creative Potential: Want to see what Vincent van Gogh would say about modern art? Or generate a video of a futuristic city based on a one-sentence description? AI removes the technical barriers to creative expression. If you can describe it, you can probably create it.
• Novelty That Stops the Scroll: The "For You" page is an endless competition for attention. The unique, sometimes surreal, nature of AI-generated content is a powerful pattern interrupt. Viewers often stop to figure out, "How did they make that?" - giving your video the initial watch time it needs to gain traction.

The Different Types of AI TikTok Videos You Can Create

The term "AI video" covers a wide range of content styles. Understanding these categories will help you decide what kind of videos you want to create for your brand or Personal Page. Here are some of the most popular formats on TikTok right now:

AI Avatars and Presenters

This is one of the most common and accessible styles. A hyper-realistic or stylized digital human speaks your script directly to the camera. It’s perfect for educational content, storytelling, brand announcements, or motivational messages. Imagine generating a consistent, on-brand spokesperson without ever setting up a camera.

Popular Use Cases: Explaining complex topics, telling historical stories, automating news updates.

Text-to-Video and Image-to-Video

These tools are game-changers. You can type a prompt like, "a golden retriever wearing sunglasses skateboarding through a vibrant city," and the AI will generate a short video clip matching that description. Similarly, image-to-video tools can take a static picture (AI-generated or a real photo) and add motion and life to it, turning a still scene into a dynamic moment.

Popular Use Cases: Creating surreal shorts, aesthetic montages, or visual loops for trending audio.

AI-Generated Animation

This approach combines text-to-image generators (like Midjourney or DALL-E) with animation tools. You create a series of character designs or cinematic scenes as still images, then use another AI tool (like Runway or Pika Labs) to add movement. It’s an incredible way to produce animated stories without needing any animation skills.

Popular Use Cases: Character-driven short stories, animated lore explainers for games or books, music video visuals.

AI Voiceovers and Scripting

Even if the visuals aren't 100% AI, the audio can be. You can use large language models like ChatGPT to brainstorm viral video ideas or write full scripts. Then, you can feed that script into an AI voice generator like ElevenLabs to create a high-quality voiceover, saving you time on recording and editing.

Popular Use Cases: “Faceless" channels that rely on interesting visuals (like gameplay or stock footage) with an engaging AI narrator.

Your Step-by-Step Guide to Making Your First AI TikTok

Ready to make something? Let’s walk through the full process of creating a common type of AI content: an educational tidbit video narrated by an AI avatar. This workflow is easy to replicate for tons of different topics.

Step 1: Ideation and Scripting with an AI Assistant

Your video starts with an idea and a script. Don’t overthink it, your first few videos are for learning. Let's use ChatGPT for this part. The goal is a script that's short, punchy, and perfect for TikTok - think around 100-150 words for a 30-45 second video.

For example, you could prompt it like this:

"Write me a 120-word TikTok script about a surprising and little-known historical fact. Make the tone friendly, enthusiastic, and easy to understand. Start with a strong hook to grab attention."

The AI will spit out a ready-to-use script. Read it aloud to make sure it flows naturally. Edit any clunky phrasing - your human touch is still important!

Step 2: Generate a Realistic AI Voiceover

Next, you need a high-quality voiceover. Hearing your own voice might not be your thing, and that's fine. Platforms like ElevenLabs or Murf AI let you convert your script into lifelike audio.

The process is simple:

1. Sign up for a voice generation service.
2. Choose a voice from their library. They offer a ton of options for different ages, accents, and tones.
3. Paste in your script from Step 1.
4. Click "Generate" and download the resulting MP3 or WAV file.

Pro Tip: Listen to a few different voices with your script to find one that matches the personality of your channel. A friendly, upbeat voice works well for fun facts, while a calm, authoritative voice might be better for business tips.

Step 3: Create Your AI Avatar Video

This is where your content starts to feel real. We’ll use an AI avatar platform like HeyGen or Synthesia. These tools let you choose a stock avatar or even create a custom one that looks like you (with some training).

Here’s the standard workflow:

1. Create your account and select an avatar from the library.
2. Choose a simple background or upload your own. For TikTok, keep it uncluttered.
3. Upload the voiceover audio file you downloaded in Step 2. The platform will automatically animate the avatar’s lip movements to perfectly match the words.
4. Preview the video. Once you’re happy with it, click "Generate" or "Export" to create the final video file.

Step 4: Editing and Adding TikTok Flair in CapCut

Your raw AI video isn't quite ready for TikTok yet. It needs captions, a little background music, and some basic cuts. CapCut, TikTok’s free sister editing app, is perfect for this.

• Import Your Video: Open a new project in CapCut and import the AI avatar video.
• Add Auto-Captions: Use CapCut's "Auto captions" feature. This is non-negotiable for TikTok, as many people watch without sound. Customize the font and style to be bold and easy to read. Fix any small errors the AI might have made in transcription.
• Add Background Music: Find a trending sound on TikTok that fits the vibe of your video. Add it in CapCut but lower its volume significantly (down to 5-10%) so it doesn’t compete with your voiceover. Having a trending sound can help the algorithm categorize and push your video.
• Make It Dynamic: Even a simple talking-head video can be more engaging with occasional "zoom-ins" or pop-up images that relate to what you're saying.

Once you’re done, export the video in 1080p and you're ready to post.
