Standard vs Master HLS output

The important difference is hierarchy

Standard output has one media playlist that directly lists segments. Master output adds a top-level playlist that points to a media playlist in a child directory.

Neither choice automatically makes the source clearer or smaller. The choice controls how a player enters the package.

Standard: playlist.m3u8 -> segment_000.ts
Master:   master.m3u8 -> 720p/index.m3u8 -> segment_000.ts

What this converter creates

For video, Master mode creates one 720p H.264/AAC rendition. For MP3, it creates one AAC audio rendition. That is a valid master hierarchy, but it is not a multi-bitrate adaptive ladder.

A true adaptive ladder needs multiple encoded renditions with aligned segment boundaries and honest bandwidth attributes.

Choose for the player

Use Standard when the player accepts a media playlist and you want the simplest folder. Use Master when an integration expects a top-level master playlist or you want a hierarchy that can later be replaced with a properly authored ladder.

• Standard primary URL ends in playlist.m3u8
• Master primary URL ends in master.m3u8
• Do not point a player at an individual .ts segment

Keep the whole result together

Extract and upload the complete ZIP. In Master mode, moving master.m3u8 without its 720p or audio directory breaks the URI inside it.

Test the exact public primary URL after deployment; a working local file does not prove server paths, headers, or CORS are correct.
