Video files are often the largest assets on a website. Proper compression can reduce sizes by 50-90% while maintaining quality.

Key Concepts

Bitrate: Amount of data per second (higher = better quality, larger file)

Resolution: Frame dimensions (1080p, 720p, 480p)

Codec: The compression algorithm (H.264, VP9, AV1)

Container: File format (MP4, WebM, MKV)

1. Lower resolution has more impact than lowering quality

2. Remove audio if not needed

3. Trim unnecessary footage before compressing

4. Use 2-pass encoding for best quality-to-size ratio
