MediaCentral | UX User’s Guide : Working with Video Media : Playing Assets : Playback of Simple and Complex Sequences

Playback of Simple and Complex Sequences
 
You can play sequences that are stored in an Interplay Production or Interplay MAM database, but some sequences require additional preparation to be completely playable.
Sequences created in Avid editing systems that include effects other than dissolves must be rendered in the editing system. You then need to check them into Interplay Production before you can play them correctly in MediaCentral UX.
Sequences that are fully supported for playback in MediaCentral UX are marked by a green triangle in the State column in the Assets pane. These sequences play as the editor intended, with all effects rendered.
*The State column is not displayed by default. For information about how to display it, see Adding or Removing Property Columns.
Simple Sequences and Complex Sequences
MediaCentral UX can play simple sequences that are checked into the Interplay Production database or the Interplay MAM database. Simple sequences are defined as:
Shotlists created in Avid editing applications (NewsCutter, Media Composer, and Symphony) and Interplay Assist that consist of cuts only, with no effects.
Sequences created in Avid Instinct and MediaCentral UX that consist of cuts, L-cuts, audio pan/volume effects, audio dissolve effects, video dissolve effects, and no more than one video track.
Edit Decision Lists (EDLs) created in Interplay MAM Desktop that have one video and one audio track, and consist of cuts only, with no effects.
Sequences that you create in MediaCentral UX are considered simple sequences. See Using the Sequence Pane.
MediaCentral UX can also play complex sequences. Complex sequences are sequences created in Avid editing applications that have multiple video tracks and various kinds of effects. If you load a complex sequence in MediaCentral UX, the MediaCentral UX playback server attempts to play the sequence. If the sequence has unrendered effects it will not play. To assure correct playback, a sequence must have all effects rendered and must be checked in again when the rendering is done.
*If you render only high-resolution effects, the MediaCentral Playback Service server plays back effects as high-resolution and plays back other segments as the proxy resolution.
An editor working in a multi-resolution workgroup can take the following approach to prepare a complex sequence for review in MediaCentral UX:
1. Make a copy of the sequence.
2. Change the Dynamic Relink settings as desired.
3. Render the copy of the sequence.
4. Check the copy in to an Interplay Production folder.
5. Restore the Dynamic Relink working resolution settings.
6. Continue working on the original sequence.
Mixing Down Complex Sequences
If a sequence is not playable in the Media viewer, and you do not want to render it, you can use the MediaCentral UX Mixdown feature to create a playable master clip. See Transcoding Assets.
