Event backup playback coordination
If the playback laptop fails during the opening video, someone has to know what happens in the next ten seconds.
The short answer
Backup playback coordination means agreeing, before show day, what the second source is for slides, video and audio, where it is physically kept, who decides to switch and how long a failure is tolerated. The AV supplier designs and operates the backup. The organiser sets what must be protected and who decides.
A backup only helps if it holds the same locked files as the main system and has been tested at rehearsal.
Decide what needs protecting
- Opening and closing videos and the awards segment, where a failure is most visible.
- Slides for a keynote speaker with no alternative materials.
- Audio such as walk-on music and any pre-recorded segment for a remote speaker.
- Lower-risk items such as break slides, which may not need a backup.
- Livestream or recording sources, if used; see recording deliverables.
Questions to ask the AV supplier
| Question | Why it matters |
|---|---|
| What backup does the supplier propose: second laptop, second playback device, or something else? | The organiser needs to understand the proposal, not design it. |
| Does the backup hold the same locked files from the asset register? | Mismatched versions cause confusion at the moment of failure. |
| Who operates it, and where is it positioned relative to the stage manager? | Switching is a joint decision, so people need to see each other. |
| How quickly can it take over, and what does the audience see during the switch? | Sets expectations for the stage manager and speaker. |
| What is tested at rehearsal? | A backup not tested at rehearsal is an assumption. |
Decide who calls the switch
- Name one decision-maker, usually the stage manager, and one deputy.
- Agree the signal between the AV desk and the stage manager, for example a short phrase on the intercom.
- Write the trigger: for example a video does not play within a time the organiser and supplier agree.
- Add the instruction to the stage cue sheet at each protected cue.
- Brief the speaker on what to do if their slides fail: pause, wait, or continue speaking.
Test it
At the technical rehearsal, rehearse a deliberate failure with the AV supplier: for example, stop the main playback at a protected cue and switch to the backup. Record how long it took and what the audience would have seen in the rehearsal issue log. Do not accept a verbal statement that the backup works.
Worked example · Fictional example
An awards evening with a short film
Fictional organisation and figures, for illustration only.
A fictional industry association has a 4-minute tribute film at its awards evening. The organiser asks the AV supplier to hold the same locked file on a second playback device next to the main desk.
At rehearsal the film is stopped on purpose; the switch takes longer than the organiser would like because the backup is at the side of the room. The supplier moves it to the main desk. The stage manager is given a script line to cover the switch and the cue sheet records the decision.
Use this yourself
Backup playback plan
Fill in one plan for each protected cue. Ask the AV supplier to confirm the technical answers.
- Protected cue and why (link to cue sheet):
- Main source and backup source (as described by the AV supplier):
- Locked files on both sources, version and date:
- Position of the backup and who operates it:
- Trigger for the switch:
- Decision-maker and deputy:
- Signal between AV desk and stage manager:
- What the speaker or host says or does during the switch:
- Time to switch measured at rehearsal:
- Confirmed by AV supplier (name, date):
Handle it in-house, or bring in help?
Your team can usually handle this when
- A short programme with few media cues and an experienced AV supplier.
- Speakers can carry on without slides if needed.
- A team member can attend the rehearsal and test a failure.
Outside planning help earns its fee when
- Video-heavy programmes, awards or hybrid sessions where a failure is very visible.
- Several playback sources: room, livestream, remote speaker.
- No one on your team can set the triggers and test them at rehearsal.
Need the backup plan agreed and tested?
A conference project lead can list the cues that need protection, put the questions to the AV supplier, write the triggers and decision-makers into the cue sheet, and make sure the failure test happens at rehearsal. The backup design and operation stay with the AV supplier.
Questions organisers ask
Does every cue need a backup?
No. Choose the cues where a failure is most visible or hardest to cover. Ask the AV supplier for a view on risk.
Who pays for backup equipment?
It is a commercial matter with the AV supplier. Ask for it to be quoted separately so you can decide.
Can the speaker carry slides on their own laptop as a backup?
It can help, but it must be agreed with the AV supplier and tested in advance, since connections and screen shapes may differ. See aspect-ratio checks.
