Project Type: AI Video Production · Commercial Advertising · Product Videography · Video Editing

Client: CJ Juice Bar Deliverable: Vertical promotional video for social media Format: 9:16 vertical Reel AI Video Clips: Approximately 8 seconds per clip Tools: ChatGPT, AI Image Generation, Google Flow (Veo 3.1), Adobe Premiere Pro

Project Overview

CJ Juice Bar is a juice and fresh-fruit business that serves customers with fruit-based refreshments. The objective of this project was to create an engaging, visually appealing promotional video showcasing the business, fresh fruit preparation, juicing process, finished drinks, and product presentation for social media marketing.

I developed an AI-assisted video production workflow that combined creative planning, image generation, reference-guided video creation, and professional post-production editing. The focus was on creating realistic commercial visuals while maintaining consistent branding, product appearance, and the overall visual identity of CJ Juice Bar.

My Role and Responsibilities

I managed the creative and technical production workflow, including:

Creative Direction: Planned the advertising concept, visual style, shot sequence, and overall storytelling for the promotional video.

AI Prompt Engineering: Used ChatGPT to develop detailed prompts for individual scenes, define visual constraints, and improve the consistency of AI-generated footage.

Visual Reference Creation: Used AI image generation to create scene references and visual starting points for video production.

AI Video Generation: Used Google Flow with Veo 3.1 to generate short video clips of approximately eight seconds each from reference images and carefully structured prompts.

Brand Consistency: Worked to preserve the original CJ Juice Bar logo, store environment, product presentation, and visual identity across the generated scenes.

Product-Focused Cinematography: Designed close-up and macro-style shots emphasizing fresh fruit, hands-on preparation, juicing equipment, juice pouring, and branded drink presentation.

Continuity Management: Developed scene-specific instructions to reduce unwanted changes in ingredients, objects, clothing, environment, and branding between clips.

Video Editing and Assembly: Used Adobe Premiere Pro to arrange, connect, and edit the individual clips into one cohesive promotional video.

Final Post-Production: Refined the sequence, pacing, transitions, and overall visual flow to create a polished vertical advertising asset.

Tools and Technologies

ChatGPT — Creative planning, storyboard development, prompt engineering, scene descriptions, and troubleshooting AI-generated video inconsistencies.

AI Image Generation — Creation of visual references and starting-frame concepts to guide the appearance and composition of individual scenes.

Google Flow / Veo 3.1 — Generation of short, reference-guided AI video clips for the advertisement.

Adobe Premiere Pro — Video editing, clip sequencing, transitions, pacing, and final assembly of the complete promotional video.

Production Workflow

1. Creative Planning and Storyboarding

I translated the client's requirements into a structured commercial sequence, identifying the key scenes needed to communicate the business and showcase its products.

2. Reference Image Development

I prepared visual references to guide the composition, store environment, fruit presentation, equipment, and branding for individual shots.

3. AI Video Production

I generated individual clips in Google Flow using Veo 3.1. Each clip was designed around a specific action, with prompts controlling camera framing, motion, scene continuity, and visual details.

4. Quality Control and Refinement

I reviewed the generated footage for inconsistencies such as incorrect branding, changing objects, unnatural hand movements, ingredient duplication, and discontinuities between scenes. I refined prompts and reference instructions to improve the results.

5. Professional Video Editing

I imported the selected clips into Adobe Premiere Pro, arranged them in the planned sequence, connected the scenes, and refined the pacing and transitions.

6. Final Video Assembly

I combined the individual AI-generated scenes into a cohesive vertical promotional video suitable for social media marketing.

Creative Approach

The project focused on using AI as part of a controlled commercial production workflow rather than generating unrelated scenes. Each shot was planned to support the overall advertisement, while reference images and structured prompts helped guide the visual continuity.

The visual direction emphasized realistic fruit textures, natural hand movements, close-up product details, recognizable CJ Juice Bar branding, and a consistent commercial aesthetic.

Project Outcome

The completed workflow brought together AI-assisted creative development, reference-based video generation, and professional editing to produce a unified promotional video for CJ Juice Bar.

The project demonstrates my ability to combine generative AI tools with conventional video-editing techniques to develop branded advertising content, manage multi-scene visual continuity, and transform individual short clips into a complete marketing video.
