Reconstruct playback state before resuming the show

Specify the state that must be reconstructed

Choose representative interruption points where playback contains more than one meaningful state: a clip running over a background bed, a paused segment or an upcoming transition. Record the intended audience picture and sound at that point. Include the selected list and next intended cue, not just a slide number or time in the run of show. Those labels may describe the story without identifying what the engine will do.

Use a rehearsal copy or approved non-live setup with no connections to machinery, effects or safety systems. Agree who observes the playback interface and who observes the receiving output. Define the scope of the exercise before executing any command. This is a controlled acceptance test, not an invitation to interrupt a live event to discover how its system behaves.

Distinguish commands by their resulting state

QLab 5’s workspace sidebar separates pause/resume-all from reset, which stops running cues and returns list playheads to their starts. GO addresses the active list’s standby cue. Sidebar panic fades and stops cues. These application controls are not emergency-system guarantees.

Have the playback specialist document the commands actually used in the show and their observed effects in the test configuration. Record active and paused items, remaining output, current standby item and any relevant pending sequence. Avoid assuming that silence means everything stopped, or that selecting the desired cue cancels earlier activity. When the system behaves unexpectedly, preserve the observation and investigate before writing a recovery instruction from memory.

Prove the next transition from the interrupted condition

For each tested interruption, state the desired recovery outcome: continue the interrupted content, restart an agreed segment or move to a prepared alternative. Let the authorized operator choose and demonstrate the product-specific steps. Observe the transition itself, including whether previous material persists, restarts, overlaps or disappears. A correct final picture can conceal an unintended burst of audio or a repeated introduction during recovery.

Test the intended next action only after confirming the starting state. Record whether the result depended on a particular list, cue selection or retained paused item. If recovery requires a complex improvised sequence, ask the show owner whether a simpler prepared playback state is preferable. Do not turn the worksheet into universal keyboard instructions: shortcuts, workspace arrangements and cue relationships differ, and an untested recipe can act on the wrong target.

Hand over evidence that another operator can use

Write the accepted recovery entry condition in observable terms. “After the clip is paused with the background bed still active” is more useful than “after a problem.” Include the expected output before and after recovery, the tested workspace revision and any limitations. Keep the run-of-show decision about whether to resume separate; this record explains the technical state required once an authorized decision has been made.

Repeat affected tests when cue relationships, playback layers or the workspace structure change. A new cue inserted near the recovery point can change what comes next without changing the visible file name. Retain failed observations and the corrected result so the next operator understands which assumption was wrong. Acceptance means the named recovery paths were demonstrated; it does not promise recovery from every failure or make application controls suitable for life-safety functions.

Make the reasoning concrete.

A fictional awards presentation pauses a nominee film while a separate background bed continues. The operator moves to the following award cue and assumes the paused film can no longer return.

The team chooses state reconstruction and records the tested outcome separately from the show caller’s authority to continue.

Use these prompts in your own notes. Nothing is submitted from this page.

1. Entry

   Which active, paused and stopped items define the interrupted condition?

2. Output

   What does the receiving audience path currently show and play?

3. Standby

   Which list and cue will the next action address?

4. Recovery

   What outcome was actually demonstrated from that state?

5. Revision

   Which workspace changes require renewed acceptance?

Watch for the wrong conclusion.

• Treating silence as proof that all playback stopped.
• Confusing the running-order position with engine state.
• Using application panic terminology as a life-safety claim.
