## Video Container Formats Explained
When downloading or streaming video content, choosing the correct container and codec directly impacts compatibility, device battery life, and storage space.
MP4 (MPEG-4 Part 14) MP4 is the universal standard for digital video storage across Android, iOS, Windows, and macOS. It offers high visual fidelity with modest file sizes using H.264/AAC encoding.
WEBM Developed by Google, WEBM is optimized for web streaming using VP9 or AV1 codecs. While highly efficient, older hardware devices may require more CPU usage to decode WEBM than hardware-accelerated MP4.
