Installation guide
Alerts: install in Streamlabs Desktop
Follower, Subscriber and Donation videos for your alert box.
In Streamlabs Desktop: Works as deliveredPut the videos in the Alert Box
- In Streamlabs Desktop: + next to Sources, Widgets tab, Alert Box (skip if your scene already has one).
- Open the Alert Box settings. For each alert type (Follow, Subscription, Donation), replace the image or video with the NanoCrea .webm of your language (07_ALERTS, folders EN, FR, DE, DA).
- Set the alert duration to 8 seconds, the length of the videos.
- The Alert Box source should cover the whole 1920x1080 canvas so the videos land where they were designed.
- Use the test buttons (Test Follow and so on): the video must play over your scene with its transparency.
Put the viewer name on the alert
- The long bar of each NanoCrea alert is the place for the viewer name. The alert video carries no text of its own there.
- In the settings of the alert, keep the message with the name variable of your alert tool (for example {name} is followed!) and set the text layout over the image, so the text sits on the bar.
- The alert videos have no sound: pick the sound in the settings of the alert, then send a test alert.
Menus are named as in the English version of the software. Checked on 23/10/2026 with Streamlabs Desktop 1.20.9 and OBS Studio 30.1.2 (Windows).
If something goes wrong
The animation has a black background
Use the .webm file (it carries the transparency) and untick the hardware decoding option of the source.
The alert does not show or shows a black box
Check that the alert box source covers 1920x1080, that the alert uses the .webm file (not the .png) and that its duration is 8 seconds. In OBS Studio, refresh the Browser source (Properties, Refresh cache of current page).
The alert or the stinger makes no sound
That is expected: NanoCrea alerts and stingers are silent videos. Pick a sound in the settings of each alert of your alert tool. In OBS Studio, tick Control audio via OBS on the Browser source of the alert box, then check its volume in the Audio Mixer.
