## What it is
An open-source, hands-on tutorial introducing digital video technology, covering image fundamentals, codecs (H.264, H.265, AV1, VP9), compression concepts, and FFmpeg encoding through practical examples. It includes Jupyter notebooks and Docker-based exercises, with translations in eight languages.

## Use cases
- learn how video codecs like h264 and av1 work
- understand video compression concepts like I, P, B frames
- get started with ffmpeg encoding commands
- learn about chroma subsampling and YCbCr color
- understand adaptive streaming with HLS and DASH
- study how motion estimation and residual coding work
- learn video technology as a software engineer

## When to choose
- you want a beginner-friendly, visual introduction to digital video concepts
- you prefer learning through hands-on exercises with real tools like ffmpeg
- you need to understand codecs, frame types, or streaming protocols from scratch

## When to avoid
- you need a comprehensive reference manual or formal specification of codecs
- you want production-ready video processing software rather than educational material
- you need an up-to-date course on the newest codec standards

## Facets
- artifact type: learning-resource
- maturity: stable
- function: video-processing, compression, developer-tools
- domain: media, tutorials, education
- platform: cross-platform, browser
- tags: video-codec, ffmpeg, h264, h265, av1, vp9, hls, dash, bitstream, jupyter-notebooks, hands-on-tutorial, adaptive-streaming, video, docker
