Project Goal

Producing a cinematic 60-second game trailer using AI-assisted workflows — combining ChatGPT for JSON prompt engineering with Google Labs Flow (Veo 3) for video generation. Suno Music AI used for the game trailer music.

Objectives

• Create a fictional brand identity (Vice Streets: City Wars) with logo, narrative, and style direction.

• Build a complete trailer sequence (intro → city flythroughs → action → branding outro).

• Compose original AI-generated music that matches the tone of a crime-action trailer.

• Showcase how AI can accelerate content ideation, scripting, and video production, and sound for  clients and entertainment media.

Tools & Workflow

1. Ideation & Branding

• Collaborated with ChatGPT to brainstorm game titles, settling on Vice Streets: City Wars.

• Designed a neon-inspired logo in the style of classic open-world crime franchises with a modern twist.

• Defined the overall art direction: Miami neon, 80s synthwave, gritty crime aesthetic.

2. Prompt Engineering with ChatGPT

• Used ChatGPT to generate structured JSON prompts for Veo/Flow.

• Prompts included detailed scene descriptions, camera directions, and logo integration.

• Built modular scenes:

  • Intro overlay (Miami skyline + logo)

  • B-roll (drone city pans, street life)

  • Chase scenes (cars weaving through traffic)

  • Shootouts (nightclub firefight, rooftop ambush)

  • Billboard insert (logo displayed in-world)

  • Outro overlay (logo end card with synth hit)

3. Music Creation with Suno AI

• Defined the audio direction: dark synthwave with cinematic trailer build-ups, heavy bass, and electronic accents.

• Used Suno AI’s generative music tools to produce multiple variations of trailer music.

• Selected a version with a rising synth intro, pulsing beats for action, and a final cinematic hit for the outro.

• Synced the Suno-generated track to the video segments for pacing and dramatic impact.

4. Video Generation in Google Labs Flow (Veo 3)

• Fed JSON prompts into Flow to generate clips in 8–12s segments for consistency.

• Iterated re-renders for problem shots (e.g., cars flying unrealistically, logo clarity on billboards).

• Combined clips using Adobe Premiere video editing software to make a cohesive trailer.

Final Deliverables

• AI-Generated Game Trailer (60s) showcasing fictional open-world crime chaos.

• Logo Design: “Vice Streets: City Wars” in neon-styled block typography.

• Original Soundtrack: Suno AI–generated dark synthwave track.

• Case Study Documentation for portfolio demonstration.

Key Learnings

• Prompt precision matters: Small phrasing changes in JSON made big differences in character design and keeping the scene fully consistent, using a master block prompts

• Breaking scenes into chunks works best: 6–12s clips are easier to control and re-run without burning credits.

• AI music integration enhances immersion: Suno AI made it possible to create a fully original soundtrack without licensing concerns, giving the trailer professional polish.

• Overlay vs. ingredient approach: Overlay ensures logo clarity; ingredient makes it immersive (billboards/signs).

• AI + Human Collaboration: ChatGPT accelerated the scripting and structuring process, freeing me to focus on creative direction.

Outcome

The Vice Streets: City Wars trailer demonstrates how AI tools can simulate AAA-level marketing assets — not just video, but also music and branding — quickly and affordably. This project proves how creatives can prototype, test, and visualize entire campaigns without full production resources.

For my portfolio, it serves as both a technical case study in AI prompt engineering and a creative exploration of end-to-end branding through storytelling, visuals, and sound.
