The media server that uses the least data

How we measured it

Measured on live Plex, Jellyfin and Emby servers with 8 film and TV test clips. Silux Media had to match or beat each server's picture quality (Netflix VMAF, every frame) before we counted every byte sent — video, audio and container.

Why it uses less data

• Modern video codecs (AV1, then HEVC, then H.264 for older devices) that need far fewer bits for the same picture
• Quality-targeted encoding: each scene gets just enough bits to look right, never a fixed, wasteful bitrate
• Efficient Opus audio instead of 256 kb/s AAC — sound that's indistinguishable at a fraction of the size
• Adaptive streaming that measures your connection every 3 seconds and never sends more than the screen needs
