I need an AI to create a 15-second ad for my mobile game for TikTok.

Creating 15-Second Mobile Game Ads for TikTok with Invideo

A 2025 guide on how to use Invideo to create dynamic, 15-second, vertical-format ads for a mobile game, perfectly optimized for TikTok.

Why This Use Case Matters in 2025

Marketing a mobile game on TikTok requires a specific type of ad: extremely fast (under 15 seconds), vertical (9:16 aspect ratio), high-energy, and visually chaotic to stop the scroll. Creating these "scroll-stopping" ads traditionally requires a deep understanding of the platform's trends and a skilled video editor. As of late 2025, Invideo can generate these ads from a single prompt, handling the formatting, pacing, and visuals automatically.

How Invideo Simplifies TikTok Ad Creation

Invideo's platform is designed for social media, with built-in understanding of platform-specific styles like TikTok.

Automated Generation (Text-to-Video)

You provide a prompt specifying the platform ("TikTok"), the length ("15 seconds"), and the game's details. The AI generates a script, generates all visuals, and assembles a video that is natively formatted for the platform.

AI-Generated & Uploaded Visuals

This is the key workflow. You can upload screen recordings of your actual gameplay. The AI will then generate new, original video clips to supplement it, such as:

• High-energy, abstract motion graphics and "gamer" style effects (fire, lightning).
• "UGC-style" clips of AI avatars (e.g., "an excited gamer yelling 'No way!'").
• Dynamic, fast-paced text animations.

AI Scripting and "High-Energy" Voiceovers

The AI will generate a very short, punchy script designed to hook a viewer. You can choose from "high-energy," "intense," or "announcer" style AI voiceovers to create the right level of hype.

Intuitive Refinement (Text-Based Editing)

After the first draft, you can use simple text commands to optimize for TikTok: "Make the cuts even faster," "Add a text overlay: 'Level 100 Boss Battle'," or "Change the music to a 'trending phonk track.'"

Step-by-Step Workflow

Step 1: Upload Media & Write the Prompt
