Can't Preview Videos in the Browser
If videos won't preview in SignPresenter's editor, it's almost always a Chrome autoplay restriction — not a problem with your video. The fix takes one click.
The error
You'll see something like:
NotAllowedError: play() failed because the user didn't interact with the document first. https://goo.gl/xX8pDD
This is Chrome blocking autoplay on a freshly loaded page. The video itself is fine — it'll play correctly on your Fire Stick.
The fix
Click anywhere inside the preview popup while it's loading. Once you've interacted with the page, Chrome allows the video to play.
As you keep using SignPresenter, Chrome learns it's a trusted site and stops blocking autoplay altogether.
We recommend Chrome for editing in general — it handles SignPresenter's video and design tools most reliably.
Still not working?
If clicking the popup doesn't help:
- Try a different browser (Firefox or Edge).
- Clear your browser cache — see Clear cache.
- Try previewing on the Fire Stick directly via Run Schedule — that's where it really matters.
If the video still won't play on the Fire Stick, see Uploading Videos → What if the video fails to process?.
