Containers vs Codecs: What’s the Difference?

Before diving into the formats, it’s important to understand two key terms:

• Container: This is the file format (like .mp4, .mov, or .mkv) that holds everything together (video, audio, subtitles, and metadata).
• Codec: This handles the compression and decompression of the video and audio streams inside the container (like H.264, H.265, or VP9).

Think of a container as a suitcase and the codec as how the clothes are packed inside. The same suitcase can carry clothes packed in many different ways.
