Gotchas
- Landscape videos and clips longer than 3 minutes are rejected. They will not publish as regular YouTube videos.
- CLI and MCP uploads need width, height, and duration on the media asset so DunSocial can confirm the clip is a Short.
- YouTube may show a note about channel requirements when you connect. Follow the on-screen guidance if it appears.
- If the channel disconnects, reconnect it from the Connect screen. DunSocial keeps the connection fresh in the background.
- YouTube also caps how many videos a channel can upload per day. DunSocial cannot raise that limit — wait for YouTube to reset it (usually within 24 hours) and try again.
