If your videos are playing in the editor, but not in the exported builds, it’s most likely that you didn’t add the video for formats to your export settings. By default Godot doesn’t put your videos in the finished export. It’s just a matter of adding ‘*.mp4’ (or any other video formats you use) to the expert settings for each platform you want to build for ;)

Thanks. Yeah, had those already as my pathways under the export tab. Been having real challenges today getting it to work. Been in it all afternoon, troubleshooting with AI best I can. Still showing a gray screen, even for dummy projects I open and test with the asset. Feel like it's probably a matter of one button not being pressed.
