If you want to share a video with friends and family members, but not have to worry about file formats and codecs (NTFS, FAT32, etc.) that may be incompatible with their computer/device, upload to Youtube. You don't even have to make Youtube videos public, as there are a couple of options that keep your upload out of public searchability. "Private" allows ONLY the person logged into the account to view the video, most likely you (the uploader). However, "Unlisted" allows the uploader to send a simple link out to acquaintances, who can then watch it on their screens without being logged in.
Eric is starting an aerial photography business and he'd like to link videos on his site. What video portals are best? Leo says most people use YouTube because it's free, but it's ad supported. Vimeo Pro is better because you don't have to use ads and can use higher resolution video. Then you embed the video into your website. That way they can watch it without leaving your website. And they all use embed codes on it. Square Space will also support it without problem. Pay for the Vimeo pro service. It's worth it.
