Environment, Accounts and Project Preparation

Lesson 02: Environment, Accounts and Project Preparation

This lesson is free.

Learning Objectives

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

• explain how “Environment, Accounts and Project Preparation” fits into the complete system
• complete the configuration or implementation step by step
• verify the result and identify common failures

Estimated Study Time

10–15 minutes

Prerequisites

Complete the previous lesson and be able to run commands in Windows CMD.

Lesson Overview

Prepare Python 3.11, Node.js, FFmpeg, AI services, and the project directory.

Core Concepts

A reliable media application requires a reproducible environment. Python coordinates the desktop application and services, Node.js runs Remotion, FFmpeg handles media, and AI services provide transcription, analysis, visual understanding, and speech generation.

Step-by-Step Instructions

Step 1: Confirm Python 3.11

python --version

Expected output:

Python 3.11.x

Create the virtual environment:

python -m venv app\.venv
app\.venv\Scripts\python.exe -m pip install --upgrade pip

Step 2: Confirm Node.js and npm

node --version
npm --version

Step 3: Confirm FFmpeg

ffmpeg -version
ffprobe -version

Step 4: Install Dependencies

app\.venv\Scripts\python.exe -m pip install -r requirements.txt
cd remotion
npm install

Step 5: Keep Credentials Safe

Store API keys in environment variables or an uncommitted .env file:

OPENAI_API_KEY=your-placeholder-key

Never include a real key in source code or a course ZIP.

Expected Result

Python, Node.js, npm, FFmpeg, and the project dependencies are available from the command line.

Common Issues and Solutions

Python points to the wrong version

Use the full Python 3.11 executable path when creating the virtual environment.

FFmpeg is not recognised

Add FFmpeg's bin directory to Windows PATH and reopen CMD.

Best Practices

Use one virtual environment per project and run pip check after installation.

Lesson Summary

The core development and runtime environment is ready.

Practice Task

Run the version checks for Python, Node.js, npm, and FFmpeg, then save the output.
