CREATING PLAYOUT SCHEDULES

A playout schedule is a schedule created with the intent of decoding the media in QuickTime files on

Pipeline, and converting to SDI for playout in real time.

Only QuickTime-compatible media files containing video and audio formats are capable of playout by

Pipeline Control. Supported video formats are DV, DVCPro, IMX, Pro Res 422, Motion JPEG. Audio must

be uncompressed, in discrete mono tracks.

Here are the steps you’ll take to create and use a playout schedule:

1. If Pipeline Control isn’t running, start it now (Opening Pipeline Control on page 96).

2. On Mac OS X, choose Schedule Recording document. On Windows, create a new, untitled schedule

(Select File > New Schedule).

3. Select the Pipeline device which you want to use to playout your video clips as SDI (Selecting a

Pipeline. (page 102)).

4. Select the video codec and configure it to meet your video decoding requirements (Selecting and

Configuring a Video Codec. (page 103)).

5. Likewise, configure the audio codec to meet your audio decoding requirements (Selecting and

Configuring the Audio Codec (page 104)).

6. Specify your clock source (Selecting a Clock Source. (page 104)).

7. Select QuickTime as your wrapper (file) format (Selecting a File Format. (page 106)). You can’t play

out media saved in TIFO files.

8. Set up handles as necessary (Setting up Handles (page 106)).

9. Optionally, select and configure a publisher to perform additional actions as part of a workflow

(Selecting a Publisher. (page 106)).

10. Save your schedule and name it, then continue.

11. Add one or more clips to the schedule (Creating Clip Events (page 130)). Each clip has a start time

and a duration.

12. Save the schedule.

13. Click the Play button to place the playout schedule into play mode.

Now, Pipeline Control displays the outgoing video stream. Pipeline Control waits for each clip event,

and delivers each clip in real-time to the Pipeline, which decodes it and plays it out as SDI.

You can only create play out schedules in Pipeline Control on Mac OS X. Pipeline Control for

Windows does not support scheduled play out.
