How to Make AI 3D Pop Up Sketch Videos | Veo 3.1 Text to Video Tutorial

Have you ever seen those mind-blowing TikTok videos where someone gently touches a sketch on paper and—boom!—the drawing magically turns into a stunning 3D object that looks alive? Whether it’s a dragon, a car, or even a mythical creature, these videos are getting millions of views, and it’s easy to see why. They mix art, technology, and a touch of magic, creating that “wow” moment we all love to see in our feeds.

What’s even cooler? You can actually make one yourself! Yup, no need to be a professional artist or a 3D designer. With the power of AI and the right prompt, you can bring your drawings to life in just a few minutes. In this article, I’ll walk you through how to create an AI-generated video where a 3D object appears when your finger touches its sketch on paper. I’ll even show you the exact prompt and settings I used, so you can try it too. Trust me, once you see the result, you’ll be hooked.

So, grab your creative spirit (and maybe your coffee), because we’re about to dive into one of the most viral AI video effects that’s taking over TikTok right now.

Step 1: Understanding the Prompt

Before anything else, let’s talk about the magic ingredient — the prompt.

A good AI video starts with a good description, and this one’s all about transforming a simple 2D sketch into a realistic 3D masterpiece.

Here’s the prompt template you’ll need:

“User input:

Object: [fill here]

A cinematic close-up of a finger gently touching an intricate pencil sketch of an [object] on an antique manuscript. As the finger touches, ripples of ink spread outward, and the 2D image magically and seamlessly transforms into a photorealistic, wet, and shiny 3D [object]. The [object] slowly lifts its head and its [object body] wiggle, as if coming to life. The entire scene is illuminated by a single, warm light source above the dark wooden table, creating a mysterious and enchanting atmosphere.”

All you have to do is replace [object] with whatever you want to bring to life. It could be an animal, a historical figure, or even something completely imaginary. In my example, I’m using “Megalodon”, the prehistoric shark that once ruled the oceans. It gives the final video an epic, cinematic vibe — like you’re watching a creature from a documentary suddenly leap out of the page.

Once you’ve customized your prompt, copy it. We’ll use it in the next step.

Step 2: Generate the AI Video Using Veo 3.1 on Flow

Now it’s time to turn that prompt into an actual video. For this, I’ll be using Flow, one of the best online tools for generating AI videos. It’s fast, beginner-friendly, and perfect for projects like this.

Here’s how I did it:

1. Copy the Prompt. First, make sure you’ve filled in your object (in this case, Megalodon) and copied the full text.
2. Go to Flow’s Official Website. Open your browser and visit the Flow platform. You’ll need to log in, but don’t worry—it’s free to get started.
3. Create a New Project. Once you’re on the dashboard, tap Create New Project to start generating a new video.
4. Select “Text to Video”. Flow offers several generation tools, but for this one, choose Text to Video. This option allows you to create entire videos from your written prompt.
5. Paste the Prompt. Now paste your customized prompt into the text box. Make sure it’s formatted correctly, as described earlier.
6. Adjust the Settings. Tap the Settings button. Here, you can customize your video’s look and output. Aspect Ratio: I recommend choosing Portrait if you’re planning to upload it on TikTok or Instagram Reels. Model: Choose Veo 3.1 – Fast Generation. It’s a reliable model that creates cinematic videos quickly without sacrificing detail.
7. Generate the Video. Hit the Send button and wait for a few minutes. The AI will start generating your video scene by scene, interpreting your prompt to create realistic lighting, movement, and 3D transformation effects.
8. Watch the Result! Once it’s done, play your video and enjoy the magic! You’ll see your chosen object (like the Megalodon) come to life from the sketch, complete with lighting, reflections, and smooth motion that looks like a high-end cinematic clip.

And there you have it! You’ve just created a viral-level AI video that’s ready to impress.

Step 3: Download and Share

After you’re happy with the result, just download the video to your gallery. From there, you can upload it directly to TikTok, Instagram, or YouTube Shorts.

To make it even more engaging, try adding some background music that matches the vibe — something mysterious or cinematic works great. A subtle sound of water or a soft “whoosh” effect can make the transformation even more realistic.

Pro tip: Use hashtags like #AIVideo, #3DEffect, #FlowAI, and #MegalodonPopUp to help your content reach more people. The more creative your object and caption are, the higher your chances of going viral.

Experiment with Different Objects

Once you’ve nailed your first video, don’t stop there! The beauty of this method is that you can experiment endlessly.

Try swapping the object in your prompt to see how different subjects react:

1. Phoenix – watch it burst into flames and rise from the ashes
2. Ancient sword – see it gleam and lift off the paper like magic
3. Human face – make a portrait blink or smile
4. Car model – have it roll off the sketchbook and drive into the scene

Each result will look unique depending on your chosen lighting, texture, and object details. It’s a great way to learn prompt engineering too, since small changes in your words can drastically affect the video outcome.

Conclusion

And that’s it — the full, step-by-step guide on how to create an AI video where a 3D object pops up when you touch its sketch on paper. What once seemed like a complex effect that only digital artists could do is now totally achievable with just a good prompt and a few clicks.

Using the Veo 3.1 model on Flow, you can easily turn your creative ideas into visually stunning clips that look cinematic and realistic. It’s fast, fun, and a guaranteed way to wow your audience.
