Video Compression Explained: Codecs, Bitrates, and Quality

2026-03-16 · ai-mp4.com Team

Video compression is a balance: smaller files vs visual quality. Understanding the basics helps you choose the right settings.

How It Works

Video codecs compress by: storing only the changes between frames (temporal compression), reducing color precision in areas the eye won't notice (spatial compression), and using mathematical models to predict motion.

Common Codecs

H.264: Universal compatibility. Good compression. The safe choice. H.265 (HEVC): 50% better compression than H.264. Some compatibility issues. AV1: Newest. Best compression. Growing support.

Our video compressor uses optimal settings for each codec automatically.
