Moodle 4.5 through 5.2. The current release is 1.18.2 (Stable).
Yes. Premium shares the same component (mod_modernvideoplayer) and carries a higher version, so you upgrade in place. Existing activities, files, progress, completion, gradebook entries, captions, bookmarks, reports, privacy data, and backup/restore data are all preserved. See Installation & Upgrade.
Uploaded and cloud videos are served through user-bound, time-limited signed URLs, with optional dynamic learner watermarking for supported sources — so credentials are never exposed and copies are traceable. See Content Protection.
No. It's best-effort browser heuristics (PrintScreen, hidden tab, focus loss, context menu) recorded in a tamper-evident, hash-chained audit log. It is deterrence and evidence, not DRM.
Yes, if you enable it. Premium emits xAPI / cmi5-style statements to an external LRS for initialized, completed, and flagged events, with asynchronous retry. See Exports & Integrations.
S3-compatible: AWS S3, Cloudflare R2, Wasabi, DigitalOcean Spaces, Backblaze B2, MinIO, and other S3-compatible stores. Also Azure Blob Storage. All are served via short-lived signed URLs. See Video Sources.
Yes. Instructor digests and asynchronous xAPI delivery run on Moodle cron, so cron must be configured and running.
Yes — GNU GPL v3 or later. You're free to modify it for your own installation.
