Each pack is an outcome preset family. Use packs to choose the behavior you want first, then tune criteria/actions if needed.

In the sections below, each heading uses a friendly label while the exact selectable pack id is shown inline.

Read Profile Pack Strategy for the rule of the road:

• fixed named packs for user-facing selection
• internal policy composition under the hood
• quality modes layered on top instead of multiplying pack names too early

Subtitle behavior is now described via the canonical policy taxonomy:

• smart_eng_sub
• all_sub_preserve
• subtitle_convert

Read Subtitle Policy for the policy model and how current packs map to it.

Quality behavior is also orthogonal to pack names:

• standard
• aggressive_vmaf

Read Quality Modes for the quality-mode model and the current implementation boundary.

If you want to see how these stock packs could be expressed declaratively, read Profile Pack YAML Examples.

Selection Model¶

Use this shorthand:

• choose a pack for subtitle + audio + delivery intent
• choose a quality mode for how hard video optimization should push

Today that means:

• pack choice is explicit
• aggressive_vmaf now exists both as a reusable quality mode and fixed named craigstreamy packs
• subtitle handling is now split more clearly across preserve vs convert variants
• both aggressive packs keep audio policy unchanged and only push video harder

Further pack evolution is documented in Profile Pack Strategy.
