> Does Discourse automatically generate video thumbnails for uploaded videos? By default, Discourse does not automatically generate video thumbnails for uploaded videos. However, the Insert Video (theme component) plugin does generate video thumbnails automatically. Is there a way to enable Discourse to automatically generate video thumbnails for uploaded videos by default? Note: The Insert Video (theme component) plugin currently only works with MP4 videos.
