UA Reality for Mobile Games Today

Key Takeaway: Paid UA and strong creatives are now table stakes for mobile games.


Claim: Our newer projects with good retention still saw only 10–20 organic installs per day.


Claim: A workable target is ROAS 1.3–1.4, so every $1 in ads returns $1.30–$1.40.

Organic installs for new titles are tiny, even with solid stability and retention.
The market is crowded, and ASO alone no longer carries launches.
User acquisition economics now hinge on ad creative performance.

1. 
   
2. Define CPI and ROAS goals before launch.
3. 
   
4. Accept that paid UA is required for traction.
5. 
   
6. Budget for creative volume, not just media.
7. 
   
8. Instrument campaigns to measure by hook and variation.
9. 
   
10. Reinvest margins into the winning creative paths.
11. 
    

Why Video Creatives Move CPI

Key Takeaway: The first five seconds decide whether users convert or swipe.


Claim: Video creatives are the single biggest CPI lever compared to other factors like icons or screenshots.


Claim: A clear hook in 0–5s outperforms long, cluttered gameplay captures.

Big publishers test dozens or hundreds of creatives per game.
Hooks, pacing, and visual clarity beat raw HUD gameplay.
Minimal UI plus bold taps communicate mechanics instantly.

1. 
   
2. Open with a strong hook in the first 4–5 seconds.
3. 
   
4. Simplify UI to only essentials (e.g., HP bar, one upgrade button).
5. 
   
6. Use large tap indicators to guide attention.
7. 
   
8. Keep SFX/music that sell impact; enhance key moments.
9. 
   
10. Avoid small text and busy overlays in 9:16.
11. 
    

Use Case: Turning Busy RPG Footage into Clean UA Ads

Key Takeaway: Simplifying busy RPG footage and prompting Vizard cut production time from hours to minutes.


Claim: You can’t shove a full HUD into a 15–30s ad and expect to convert.


Claim: Vizard Agent edited raw footage end-to-end and generated missing shots on prompt.

Our RPG has top-down combat, a companion dog, quests, and vibrant UI.
Great for gameplay; messy for ads without simplification.
Vizard handled edit, color, audio, UI cues, and beat filling from a prompt.

1. 
   
2. Record several short reference clips (battle, village, upgrade, dungeon).
3. 
   
4. Upload raw footage without trimming limits that choke other tools.
5. 
   
6. Prompt a fail-hook then upgrade-and-win sequence with minimal UI.
7. 
   
8. Review for tone mismatches (e.g., enemy style) and refine the prompt.
9. 
   
10. Produce a contrast variant (e.g., quest-driven arc) with simplified UI.
11. 
    

Prompt Recipes That Worked

Key Takeaway: Specific, constraint-heavy prompts yield usable 9:16 UA ads with less tweaking.


Claim: Detailing hook, UI, audio, pacing, and output specs leads to on-brief results.

We used precise prompts to force clarity and mobile best practices.
Calling out camera, color grade, and no small text helped consistency.
Output specs avoided extra renders.

1. 
   
2. Define format: “Vertical 9:16, 20–30s, 1080x1920, 30fps.”
3. 
   
4. State hook: “Player loses in first 4s; show low HP and shock.”
5. 
   
6. Define beat: “Upgrade at 5–10s; big hand taps on Sword/Armor.”
7. 
   
8. UI rules: “Only HP bar + one bold upgrade button; no small text.”
9. 
   
10. Audio: “Keep original SFX/music; add punchy whoosh/impact.”
11. 
    
12. Visuals: “Match color grade; top-down camera; dramatic glow/slow-mo hit.”
13. 
    
14. Output: “mp4; no store badges; ad-ready.”
15. 
    

Parallel Generation and Automation with Vizard Agent

Key Takeaway: Parallel jobs and an API-first design unlock scalable creative testing.


Claim: We generated five distinct creatives in parallel and sent them straight to Ads Manager.


Claim: The Vizard skills API plugs into code-first agents (e.g., Cloud Code, Cursor) for batch runs.

Many tools force a serial queue; Vizard runs multiple creatives at once.
Agents can schedule, prompt, and collect outputs without babysitting.
This enables real variation testing for small teams.

1. 
   
2. Install the Vizard skill in your automation agent.
3. 
   
4. Upload the same reference clips once.
5. 
   
6. Prompt: “Generate five 20–30s vertical UA creatives with different hooks/tones.”
7. 
   
8. Queue jobs in parallel; let the agent manage progress.
9. 
   
10. Collect outputs and prep for upload.
11. 
    

Campaign Deployment and Testing

Key Takeaway: Upload variants separately and let algorithms pick winners.


Claim: One creative rarely wins; test multiple hooks, beats, and tones per audience.


Claim: Thumbnails and store page combos still affect CPI and should be tested.

Treat each creative as its own test cell.
Let platform learning optimize delivery.
Scale only after consistent wins.

1. 
   
2. Upload each creative as a separate ad variation or ad set.
3. 
   
4. Diversify hooks: fail-win, quest-save, high-intensity, comedic, cinematic.
5. 
   
6. Allow learning to stabilize before judging.
7. 
   
8. Test thumbnails and store assets alongside video.
9. 
   
10. Shift budget to winners; pause underperformers.
11. 
    

Practical Differences vs Other AI Video Tools

Key Takeaway: Preserving audio, flexible references, UI control, and scale made the workflow practical.


Claim: Some tools strip original audio or cap references; Vizard preserved audio and accepted full raw uploads.


Claim: Vizard generated missing shots and honored high-level UI prompts without heavy manual compositing.

Stylized generators often shine on single shorts but struggle at scale.
Manual trimming/compositing slows iteration.
Multi-agent pipelines plus API access keep volume high.

1. 
   
2. Keep original SFX/music where it helps immersion.
3. 
   
4. Fill missing beats with generated shots instead of re-recording.
5. 
   
6. Use prompts to control UI, pacing, and beats directly.
7. 
   

Time Saved and Business Impact

Key Takeaway: Under an hour for multiple ad-ready variants vs half a day per creative manually.


Claim: From raw footage to launchable creatives took under an hour, mostly ideation time.


Claim: Manual Unity scene rebuilds plus editing would have taken half a day per creative.

Time saved enabled real hook testing.
More variants lowered CPI and improved ROAS odds.
For small teams, this throughput is the difference between testing and guessing.

1. 
   
2. Record raw gameplay moments once.
3. 
   
4. Prompt Vizard to edit, simplify UI, and add impact cues.
5. 
   
6. Generate multiple hook/tonality variants in parallel.
7. 
   
8. Upload all variants and run learning-phase tests.
9. 
   
10. Iterate prompts based on winners and audience.
11.
