Does Projection Mode cover every network-loss scenario?

No. The current public claim is narrower: prepared local projection can continue when the ASM console and Projection Window were already open and prepared before venue internet loss. This does not cover browser refreshes, reopened-browser recovery, or audience mobile viewers without cloud connectivity.

What should I test before relying on local projection continuity?

Before showtime, save the preset, open Projection Screen A, confirm the Projection Window responds, then run a controlled offline test. In Chrome, press F12, open Network, change No throttling to Offline, test the cues, then switch back to No throttling.

Preparing Projection Mode for Showtime | SurtitleLive Guides

Use for: Theatre projector workflows and prepared local projection continuity.

Core rule: prepare before showtime and keep both ASM and the Projection Window open.

Important boundary: If ASM and the Projection Window are already open, projected text may keep responding during venue internet loss. Audience phones do not get that same protection. Mobile surtitles stay cloud-delivered, so if the venue has no internet, phones will not keep receiving subtitles.

What Projection Mode Covers

Projection Mode is designed for theatre projector workflows: a computer connected to the venue projector or LED screen opens a Projection Window, and the ASM console cues the projected surtitles during the show.

When the setup is prepared before showtime, already-open ASM and Projection screens may keep responding during venue internet loss. This does not mean the whole SurtitleLive workflow works without internet, and it does not extend to audience phones.

Prepare the room before the audience enters

Open the ASM Console and unlock it.
Open Projection Mode Setting.
Use Save Preset and confirm the preset is ready for the venue screen.
Open Projection Screen A and confirm the Projection Window connects.
Keep the Projection Window open on the computer connected to the projector or LED screen.
Confirm that cue changes in ASM move the Projection Window before the audience enters.

Test prepared local projection continuity

Run this only after the normal live path already works.

Deploy the show and open ASM.
Open the Projection Window and confirm it responds.
Go Live.
After both windows are already open, press F12 in Chrome, open the Network tab, change No throttling to Offline, run the test, then change it back to No throttling when you finish.
Advance, jump, and blackout from ASM.
Confirm the already-open Projection Window still responds.

What This Does Not Cover

It does not mean the whole SurtitleLive workflow works without internet.
It does not cover browser refreshes or reopened browsers after venue internet loss.
Mobile surtitles stay cloud-delivered.
It is not a guarantee against interruption.

Practical Show Checklist

Use a dedicated projector computer where possible.
Keep ASM Console and Projection Window open for the whole show.
Test the projector resolution, text size, and blackout behavior in the room.
Test mobile surtitles separately on the venue network if audience phones are part of the plan.
Keep an export or backup display plan for venue-device, browser, or power failures.
