Question

The video on the box cannot be previewed online.

Hi everyone,

We noticed a strange issue with Box video preview.

We uploaded the same video file (about 5MB) to two different folders:

  • one for internal use
  • one for external access

The video plays smoothly in the internal folder, but in the external folder it just keeps spinning/buffering and won’t preview properly.

We also tried uploading another small video file (about 1MB) from a different account, and that one also could not be previewed online.

Since both files are very small, we’re wondering if this could be related to folder settings, permissions, or shared link settings.

Has anyone seen this before or know what might cause it?

Thanks!
