Video Playback Issues

Video won’t play or shows a blank area

Try these first:

YouTube content is embedded directly in Juno. Common issues:

Network blocking: If your company’s network or firewall blocks youtube.com, embedded videos won’t load. Try on a different network (e.g. mobile data) or contact your IT team.
Video unavailable: The video may have been set to private or removed by the creator. Contact your admin to update the content.
Aspect ratio: YouTube videos display in a fixed 16:9 ratio. Black bars may appear if the original video has a different aspect ratio — this is normal.

Videos uploaded directly to Juno (not from YouTube or Vimeo):

Still processing: Recently uploaded videos may take a few minutes to become available. If the video was just added, wait and try again.
Blank player: If the video area appears but nothing plays, the file may be in a format your browser doesn’t support. Contact your admin.
Slow loading: Large video files on a slow connection may take time to buffer. Wait for the loading indicator to complete.

Juno’s video player supports:

If any controls are missing or unresponsive, try refreshing the page.

SCORM content (interactive e-learning modules) opens in an embedded viewer within Juno. Common issues:

Blank frame: The embedded viewer may fail to load. Try refreshing the page or clearing your browser cache.
“No valid SCORM file found”: The uploaded package has an error. Contact your admin — they may need to re-upload the SCORM file.
Progress not saving: SCORM packages control their own completion tracking. If you’ve finished the module but Juno still shows it as incomplete, the package didn’t send a completion signal. Contact your admin to manually mark it complete.

If your organization uses Juno’s built-in video recording feature:

Recordings are saved in WebM format. Most modern browsers support this, but Safari on older macOS versions may not.
If you can’t play back a recording, try opening it in Chrome.
Download failures may show a “format not supported” message — this is a browser limitation, not a Juno error.
