All video effects—both Fixed and Standard effects—are clip‑based. That is, they alter individual clips. Since all clips include Fixed effects, you only need to apply Standard effects to a clip to create a result. 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 the Timeline panel.
