YouTube alerts need a channel connection, an alert widget, and media to play. AlertForge creates the media. A provider such as Streamlabs connects the supported YouTube events to that media, and OBS displays the widget.

Choose the events first

Check your widget's YouTube settings before creating the set. Subscriber notifications, memberships, Super Chat, and Super Stickers depend on channel eligibility and provider support. Not every subscription is visible to third-party tools.

Super Chat and Super Stickers are live-chat features for eligible streams and Premieres. Super Thanks applies to eligible long-form videos and Shorts; do not treat it as an interchangeable live Super Chat event.

There is no separate YouTube "channel follow" event equivalent to a Twitch follow. Use the event names your connected provider actually supports.

Create the alert media

You can use a theme, upload a video you already own, or generate one with AlertForge. For a matching pack, choose one visual direction and review each result for consistent colours, characters, and lettering.

AlertForge's existing alert templates are not dedicated integrations for every YouTube event. Create suitable media, then assign it to a supported event in your widget. Leave space for the widget to display changing names and messages rather than baking them into the video.

The standalone transparent video builder exports the finished video. Audio is optional and off by default. Uploading a reference is free; AI reference generation and video generation use credits, with the quote shown before confirmation.

How to connect the files to OBS

Sign in to your alert provider and connect your YouTube channel.
Open the supported event you want to customize.
Upload your transparent WebM as its alert media.
Set the duration to match the clip and check text placement and sound.
Copy the widget URL and add it as an OBS Browser Source.
Place it above your gameplay or camera sources.
Use the provider's test event and inspect a short OBS recording.

Streamlabs' YouTube guide explains its channel-connection and widget setup. Our AlertForge OBS guide covers where each exported file goes.

Browser Source or Media Source?

Use a Browser Source for a connected alert widget. The widget listens for events and plays the uploaded media.

Use a Media Source for a local file you want to preview or trigger manually. You can configure playback and assign hotkeys, but a Media Source does not detect YouTube events by itself. Automatic local playback requires a separate integration; hiding and showing a file is not an event connection.

Both approaches can display the same transparent WebM. Custom files and a connected widget work together; they are not competing choices.

Troubleshooting

A test works but real events do not: check the channel connection, eligibility, and provider event support. A test animation alone does not prove the live integration.
Black background: use the original alpha-channel WebM, not an MP4 conversion.
No sound: confirm the generated clip contains audio and check both widget and OBS mixer settings.
Duplicate sound: disable either the video's audio or the separate widget sound.
Text covers the animation: adjust the widget layout and test with a long name or message.

Do not spend money sending a real Super Chat just to test your design. Use the provider's test controls. YouTube restricts Super Chat availability on private and unlisted videos, so those are not a substitute for an eligible live event.

FAQ

Can the same video be used on Twitch or Kick? Yes, when the destination accepts the format. Configure event routing separately for each channel.

Does a WebM trigger automatically? No. It is a media file, not an event listener.

Does AlertForge supply a separate sound-effect file? The standalone video builder supplies the finished video. Do not plan around a separate audio download.
