Course Introduction and Final Product

Lesson 01: Course Introduction and Final Product

This lesson is free.

Learning Objectives

By the end of this lesson, you will be able to:

• understand how this lesson fits into the full system
• complete the relevant configuration or implementation
• verify the result and prepare for the next step

Lesson Overview

Understand the project goal, commercial use cases, final application features, and learning path.

Final Project Outcome

By the end of the course, you will have a Windows desktop tool that can:

• open by double-clicking launch.bat
• accept Chinese and English tool names and descriptions
• accept 4–10 images in exact upload order
• optionally accept 0–3 demo clips
• generate Chinese and English MP4 files
• play AI narration during image sections
• preserve demo audio while narration pauses

Core Workflow

Enter descriptions
→ Upload images and demos
→ Validate and create a render job
→ Generate Chinese and English narration
→ Build the Remotion timeline
→ Export Chinese and English MP4 files

Step-by-Step Instructions

Step 1: Confirm the Current Project State

Before continuing, confirm that the project directory, dependencies, and previous lesson output are working. Commands in this course use Windows CMD.

Step 2: Complete the Lesson Implementation

Create or update the relevant files shown in this lesson. Keep responsibilities separated instead of placing GUI, file handling, TTS, and Remotion rendering in one file.

Step 3: Run Checks

After making changes, run syntax checks, relevant automated tests, and one minimal functional check.

Common Issues

Why must upload order be preserved?

A showcase video normally follows a deliberate product workflow. Sorting by filename can destroy that sequence, so array order must remain authoritative.

Why use a separate job folder?

A unique job folder prevents different generations from overwriting each other and provides a clear place for media, logs, JSON, and troubleshooting evidence.
