Q: Videos in shared albums?

Hello there, sourthwestform.

It sounds like you want to know if videos can be shared with iCloud photo albums. The short answer is yes. The following Knowledge Base article provides a great resource for iCloud Photo Sharing:

iCloud Photo Sharing FAQ - Apple Support

With iCloud Photo Sharing, you can share photos and videos with just the people you choose, and you can let them add their own photos, videos, and comments. Friends and family can subscribe to your shared albums to view them on all of their devices, leave comments, and get notified automatically when you add new photos and videos.

What do I need to use iCloud Photo Sharing?

To use iCloud Photo Sharing, you need an iCloud account (Apple ID), compatible devices, and up-to-date software:

• iPhone, iPad, or iPod touch using iOS 7 or later
• Mac using OS X Mavericks v10.9 or later and either iPhoto 9.5 or Aperture 3.5
• Apple TV with Apple TV software 6.0 or later
• PC using Windows 7 or later and iCloud for Windows (or iCloud Control Panel 3.1 or later)

If you enabled the Public Website option when you set up your shared album, your friends and family can view your photos and videos from any current web browser using a link that you provide.

How long are iCloud Photo Sharing photos and videos stored in iCloud?

The photos and videos you share (and the comments or likes associated with those photos) remain in iCloud until you or the contributor delete them manually, or until you delete the shared album completely.
