Understanding Basic and Advanced Sequences

When you create a sequence from the Assets pane, you can choose whether to create a basic sequence or an advanced sequence. Interplay Production supports basic sequences and advanced sequences. Interplay MAM supports only basic sequences.

• A basic sequence includes a timeline with one video track and one audio track. The single audio track represents all source audio tracks. A portion of media that is contained on a track in a sequence is called a segment. The following illustration shows a basic sequence with one video segment and one audio segment.

A basic sequence consists of cuts only. It is sometimes referred to as a shotlist or a cut list, or, in an Interplay MAM context, as an EDL (Edit Decision List). You cannot add video dissolves or audio dissolves to a basic sequence.

All source audio tracks in the clips that compose a sequence are monitored in a single audio meter. You can select which channels are monitored. See Audio Monitoring for Assets and Basic Sequences.

- Interplay MAM supports audio-only basic sequences, which contain one audio track but no video track (see Audio-Only Basic Sequences (Interplay | MAM)). It does not support video-only basic sequences.

- Interplay Production does not support audio-only or video-only basic sequences.

• An advanced sequence includes a timeline with one video track. By default it includes three audio tracks, named NAT (natural sound), SOT (sound on tape), and VO (voice-over) for use with iNEWS stories. You can create a sequence that is associated with an iNEWS story, or you can create and edit an independent sequence.

Different colors for segments in the timeline indicate relationships between the segments:

- Video with associated SOT, Video with associated NAT and SOT, or SOT only: light blue

The following illustration shows, from left to right, Video with NAT and SOT, VO, Video with NAT, and Video only.

An administrator can rename the audio track labels. An administrator also determines the audio track mapping, which you can change. For information on renaming, mapping, and configuring audio tracks, and adding audio dissolves, see Working with Audio Tracks in Advanced Sequences.

You can add video dissolves to an advanced sequence. See Inserting Video Dissolves (Advanced Sequences Only). Audio dissolves are added automatically. See Working with Audio Tracks in Advanced Sequences.

Interplay Production supports audio-only and video-only advanced sequences. See Audio-Only and Video-Only Advanced Sequences (Interplay | Production).

When you create a sequence from the Queue/Story pane, the sequence is automatically created as an advanced sequence.

You cannot convert a basic sequence to an advanced sequence, or an advanced sequence to a basic sequence.
