Sei Media Formats

The Sei Media Formats are read-only text files designed to store audio/video content for playback on SAE/SAL and SVE/SVL compatible players. There are four types of formats, as listed below.

Sei Audio Embedded (.SAE)

This format is designed for chained audio files with UUIDs directly embedded into the file. This is used primarily for short audio clips.

Sei Audio Linked (.SAL)

This format is designed for chained audio files indirectly hosted on the NTBI Group Media Database. This is used for longer audio clips, music, etc.

The advantages to using link-hosted files is that it dramatically decreases the filesize - while .SAE files take up 32 bytes for every 10 seconds of audio, .SAL files only take up 32 bytes for the reference link and do not expand based on file length. This only affects the length of the .SAL file itself - when played, the equivalent .SAE file is internally generated anyway in the player. Note that the resulting file will still be greater than 32 bytes due to header information.

Sei Video Embedded (.SVE)

This format is designed for chained audio/video files with UUIDs directly embedded into the file. This is used primarily for short video clips.

Sei Video Linked (.SVL)

This format is designed for chained audio/video files indirectly hosted on the NTBI Group Media Database. This is used for longer video clips.

Like .SAL files, .SVL files benefit greatly due to less space required in the file itself. This is especially useful for video, since .SVE files take up 64 bytes for every 10 seconds due to having an audio and video stream, while .SVL files only take up 32 bytes for the reference link.
