8.3. Mix and Preset Files

A .hdjmix file contains the current Mix document: its track references, order, roles, locks, exclusions, target values, key profile, transition-profile snapshot, rules, authored incoming-transition explanations and context, sharing details, and other planning state. It does not contain audio, private undo history, or the live association with a published Mix page. Importing the file creates a new local Mix identity, so it cannot update or advertise the source Mix’s published page. Duplicate Mix follows the same rule.

Exported transition presets contain a reusable transition profile. Applying one copies that profile into the active Mix; the Mix does not depend on the preset file remaining available later.

Mix import and export, along with transition-preset management, are available in Community. Imported Mixes with five or fewer tracks are editable there. Larger imported Mixes remain readable and auditionable until Pro is active. Imported Mixes and presets are validated before replacing local state. Keep exports alongside normal project backups when a tracklist or custom relationship is important.
