Static Buffs - A static buff is a buff that snapshots. The buff does not scale off any attribute, or if the attribute which the buff scales off changes during the buff's duration, the buff will not change.
Dynamic Buffs - A dynamic buff is a buff that does not snapshot. If the attribute which the buff scales off changes during the buff's duration, the buff will change.
Direct Buffs - Buffs that do not modify the damage dealer's attributes, and instead directly apply to real-time damage calculations. These buffs are completely unaffected by snapshotting. This is a separate concept from Static and Dynamic Buffs and coexists with them.
If a buff results in a visible change in the stat menu (e.g. ATK buffs, Elemental DMG Bonus buffs), it is not a direct buff. If a buff does not result in a visible change in stats (e.g. Elemental Burst DMG Bonus buffs, Flat DMG Bonus buffs), it is a direct buff.

Direct Buffs do not change the stats of the character, and instead directly affect the damage output of the character after a snapshotting Skill/Burst is cast. These buffs include:
