About clip‑based and track‑based effects

All video effects—both Fixed and Standard effects—are clip‑based. They alter individual clips. You can apply a clip‑based effect to more than one clip at a time by creating a nested sequence.

Audio effects can be applied to either clips or to tracks. To apply track‑based effects, use the Audio Mixer. If you add keyframes to the effect, you can then adjust the effect either in the Audio Mixer or a Timeline panel.
