Each time you record or import audio, video, and MIDI, Pro Tools creates
clips for the new track data, which not only indicate where the material begins and ends, but also provides visual feedback on its general character and content. When you record additional takes, or “punch in” on a specific location within a track, Pro Tools creates additional clips.
Clips are also created by cutting and pasting, resizing, separating, and re-capturing existing clips. Clips in a session are listed in the Clip List, where they can be dragged to existing tracks. A track can contain any number of clips, in any arrangement. The order and location of clips in a track define its
playlist.
In addition to audio and MIDI clips, tracks provide automation playlists of any automation data (such as volume and pan). Automation can be recorded and edited in the Mix, Edit, and MIDI Editor windows (see
Automation).
