How to Make a Game Teaser with Veo 3: A Step-by-Step Walkthrough
So, you’re making a game. You've poured your heart, soul, & countless late nights into creating a world, a story, a set of mechanics that you KNOW people will love. But here's the thing: how do you get them to see what you see? How do you capture that magic & share it with the world? The answer, my friend, is a killer game teaser. & it turns out, you don't need a Hollywood budget to make one anymore.
Enter Veo 3, Google's latest AI video generator that's been making some serious waves. This thing is a beast, turning simple text prompts into high-definition video clips, complete with synchronized audio. Yeah, you read that right – dialogue, sound effects, music, all baked in. For indie devs or even larger studios looking to visualize ideas fast, this is a total game-changer. I’ve been playing around with it, & honestly, it’s pretty impressive.
We’ve seen indie teams put together entire story trailers with Veo 3 for under a couple hundred bucks in a week. That’s insane. It's democratizing the ability to create high-quality marketing materials. But, like any powerful tool, there's a learning curve. You can't just type "make my game look cool" & expect a masterpiece.
That's why we're here. This is your step-by-step walkthrough for making a jaw-dropping game teaser using Veo 3. We'll go from the initial spark of an idea to the final, polished video that will get players hyped.
Part 1: The Blueprint – Pre-Production & Planning
Before you even think about opening Veo, you need a plan. A great teaser isn't just a random collection of cool shots; it's a short story. It needs a beginning, a middle, & an end. This is where you lay the foundation for everything that follows.
Conceptualization: What's the Vibe?
First things first: what is the core feeling of your game? Is it a heart-pounding sci-fi thriller? A whimsical fantasy adventure? A gritty, post-apocalyptic survival story? Your teaser needs to ooze this feeling from every pixel.
Think about your target audience. What gets them excited? What are their expectations for a game in your genre? Your teaser is your first point of contact with them, so you need to speak their language.
At this stage, just brainstorm. Write down keywords, themes, & emotions.
Genre: Sci-fi, fantasy, horror, slice-of-life
Mood: Mysterious, action-packed, somber, comedic
Key Features: What are the 1-3 things that make your game UNIQUE? Is it a novel mechanic? A stunning art style? A compelling character?
Storyboarding: Your Comic Book of Cool
Okay, you've got your concept. Now, let's visualize it. A storyboard is basically a comic strip version of your teaser. & don't worry, you don't need to be a professional artist. Stick figures & rough sketches are totally fine. The goal is to plan your shots & the overall flow.
A typical game teaser is short, usually 60-90 seconds. Don't try to cram your entire game's plot into it. You want to tease, not spoil. Here's a simple structure to follow:
The Hook (0-10 seconds): Start with something that grabs attention IMMEDIATELY. A stunning landscape, a mysterious character, an explosive action sequence. Make them stop scrolling.
Introduce the World & Conflict (10-30 seconds): Briefly establish the setting & the central problem. Who is the protagonist? What are they up against?
Showcase Gameplay/Key Features (30-50 seconds): This is where you show, not just tell. Demonstrate what makes your game fun & different. Focus on 1-3 key mechanics.
Escalation & Climax (50-80 seconds): Raise the stakes. Show a montage of increasingly exciting moments, building to a big reveal or a powerful emotional beat.
The Call to Action & Title Card (80-90 seconds): End with your game's logo, the platforms it'll be on, & a clear call to action (CTA), like "Wishlist on Steam" or "Coming Soon."
For each scene in your storyboard, jot down a few notes:
What's happening in the shot?
What's the camera angle (e.g., wide shot, close-up)?
Any specific text on screen?
What's the audio cue (e.g., dialogue snippet, sound effect)?
Remember, this is your roadmap. Having a solid storyboard will make the AI generation process SO much smoother.
Part 2: The Magic Wand – Generating Your Scenes with Veo 3
Alright, the planning is done. Now for the fun part. It’s time to bring your vision to life. Veo 3 is currently accessed through Google's Flow interface, & you'll likely need a subscription plan to get going. Once you're in, it's all about the prompts.
The Art of the Prompt: Speaking AI's Language
This is the most critical skill you'll need to master. Veo 3 is powerful, but it's not a mind reader. The quality of your output is directly tied to the quality of your input. A vague prompt will get you a vague video.
Here's a proven formula for writing effective prompts:
Shot Type: Be specific about the camera. Use terms like "wide shot," "close-up," "overhead view," "tracking shot," "handheld camera with subtle shake."
Subject: Who or what is the focus of the shot? "A heavily armored space marine," "a small, glowing creature," "a futuristic motorcycle."
Action: What is the subject doing? Keep it to a single, clear action per prompt. "running through a neon-lit alley," "casting a powerful magic spell," "looking out over a vast, ruined city."
Scene/Environment: Describe the background & setting in detail. "A dense, foggy forest at midnight," "a bustling cyberpunk marketplace," "the interior of a derelict starship."
Modifiers: This is where you add the artistic flair.
1
Cinematic wide shot of a lone knight in silver armor, holding a glowing sword, standing at the edge of a dark, enchanted forest at dusk. Eerie, mysterious mood, with volumetric lighting filtering through the ancient trees.
Bad Prompt:
1
dragon flying
Good Prompt:
1
Dynamic tracking shot of a massive red dragon flying through a stormy sky, breathing a torrent of fire towards the camera. Epic fantasy style, photorealistic, dramatic lightning flashes.
Pro-Tips for Prompting:
One Idea Per Prompt: Don't try to create multiple scenes in a single prompt. Veo works best when focused on one shot at a time.
Be Detailed: The more visual details you provide, the better. Mention colors, textures, weather, time of day.
Character Consistency is Key: This is a known challenge with AI video. To keep your character looking the same across different shots, try using an initial image prompt. Generate a character sheet or a key art image of your protagonist first. Then, you can use that image as a starting point for your video prompts to guide Veo. Some users on forums have had success with this "image-to-video" approach to maintain consistency.
Dialogue & Audio: Veo 3's native audio generation is a huge plus. To use it, include dialogue in your prompt. For example:
1
Medium shot of a grizzled detective saying, "I've seen it all, but this... this is different."
Also, describe background sounds: "sound of heavy rain," "distant sirens," "machinery humming."
Generate each shot from your storyboard one by one. This will take time & experimentation. Don't be afraid to regenerate a clip multiple times, tweaking the prompt until it matches your vision.
Part 3: The Cutting Room Floor – Post-Production & Polish
You've got a folder full of awesome AI-generated clips. Nice! But you're not done yet. A teaser isn't just a slideshow; it needs to be edited together into a cohesive, impactful whole. This is where you become the director.
Editing: Stitching It All Together
You'll need a video editing software for this. Something like CapCut (which is free & surprisingly powerful) or Adobe Premiere Pro will do the trick.
Assemble Your Timeline: Lay out your clips in the order of your storyboard. This is your rough cut.
Pacing & Timing: This is EVERYTHING. Trim the fat from each clip. Keep the pace moving. A good rule of thumb is to cut to the beat of your music. Use a mix of fast cuts for action sequences & slower, more deliberate pacing for emotional moments. The ideal length is under two minutes, so be ruthless.
Transitions: Simple cuts are often the most effective. But don't be afraid to use a few stylish transitions, like a quick zoom or a fade to black, to add emphasis. One YouTube tutorial suggests using a "horizontal open" effect at the beginning & a "horizontal close" at the end for a cinematic feel.
Text & Graphics: Add your title cards, feature callouts ("Forge Your Own Path"), & your final CTA. Use a font that matches your game's aesthetic. Keep the text short & punchy—no more than 5-6 words at a time.
Sound Design: The Secret Weapon
Visuals are only half the battle. Sound is what sells the emotion.
Music: This is the soul of your teaser. Choose a track that matches the tone of your game. You can find tons of copyright-free music on YouTube or use a service like Suno AI to generate a custom track. The music should have a clear structure—a build-up, a climax, & an outro—that you can edit your visuals to.
Sound Effects (SFX): Even if Veo generated some ambient sounds, you'll want to layer in more specific SFX. The clang of a sword, the roar of a monster, the whir of a spaceship door—these details make your world feel real.
Voiceover/Narration: If you have a narrator, now's the time to add it. You can use an AI voice generator like ElevenLabs for a high-quality, cost-effective solution. Make sure the audio levels are balanced. The voiceover should be clear, but not so loud that it overpowers the music & SFX.
Color Grading & Final Polish
The final step is to give your teaser a consistent look. All your clips might have slightly different color tones. Use your editing software's color correction tools to apply a consistent filter or "LUT" across the entire video. This will tie everything together & give it that professional, cinematic look.
Beyond the Teaser: Engaging Your Newfound Audience
You've done it. You've created an incredible game teaser. You've uploaded it to YouTube, Twitter, TikTok. The views are rolling in, people are hyped in the comments. Now what?
This is where the real work of community building begins. A teaser is a promise, & you need to continue the conversation. This is actually a perfect use-case for modern AI tools that go beyond video generation.
Here's the thing, you're going to get a LOT of questions: "When is the release date?" "What platforms will it be on?" "Can I play as the dragon?" Answering all of these manually is a full-time job. This is where a solution like Arsturn becomes incredibly valuable. You can build a no-code AI chatbot, trained on your own game's data (like your FAQ, dev blogs, & press kit). This chatbot can live on your website & instantly answer those common questions 24/7, keeping your new fans engaged while you focus on, you know, actually finishing the game. It helps you build a meaningful connection with your audience from day one.
Common Mistakes to Avoid
Making a teaser with AI is a new frontier, & it's easy to make a few missteps. Here are some common pitfalls to watch out for:
Over-relying on AI: AI is a tool, not a director. Don't just accept the first thing it generates. Guide it, refine it, & add your own human creativity in the editing process.
Ignoring Storytelling: Stunning visuals with no story are just a tech demo. Make sure your teaser has a clear narrative arc, no matter how simple.
Inconsistent Visuals: The "AI look" can be a problem. Use image-to-video prompts & consistent style modifiers to avoid your character changing their face in every shot. Brand consistency is key.
Poor Audio Quality: Don't neglect sound design. Bad audio can ruin even the most beautiful visuals.
Making it Too Long: Keep it short & sweet. It's better to have a 60-second trailer that's all killer, no filler, than a 3-minute one that repeats itself & makes your game look smaller than it is.
Creating a game teaser with Veo 3 is an incredibly powerful way to showcase your vision to the world. It’s a process that blends creative direction with technical skill. It requires planning, patience, & a willingness to experiment. But the ability to create a professional-quality trailer on an indie budget is a massive leap forward for developers everywhere.
So go on, start storyboarding. Write some killer prompts. Fire up that video editor. The world is waiting to see what you've created.
Hope this was helpful. Let me know what you think, & I can't wait to see the amazing teasers you all come up with.
