Apple introduced the ability to share files in iCloud Drive starting with macOS High Sierra and iOS 11. The new sharing option is called Add People, and it creates a sharing link to a file you've uploaded to iCloud Drive. So when you upload a video and set the options in Add People, iCloud sends a link to the people you want to view the video. They don't download the file; it stays where it is.

iCloud accounts are free for anyone with an Apple ID, which is also free. Create and access an iCloud account on your iPhone, iPad, iPod touch, and Mac computer. If you have a Windows PC, you’ll get web-only access to iCloud anywhere you have an internet connection.

iCloud comes with 5GB of free iCloud storage, which is shared with other Apple services. If you plan on uploading a lot of video, 5GB might not be enough. Apple offers several tiers of paid storage, starting at 50GB for $0.99 per month. Subscriptions go up to 2TB and can be shared with your family.

Whether you're making homemade movies in iMovie or short videos to post on social media, you can upload the video file to your iCloud account if you want to share it with others.
