Ed converted a bunch of home movies into digital format on a USB key. He wants to share them with family, but he has to convert them. What does he do? Leo says that as long as the USB key is formatted for FAT32 or ExFAT, it should be compatible with both. NTFS won't work for most macs. Then there's the video format. If it's WMV, Macs can't play it back. But MP4 is modern and ubiquitous. What if the person he's sharing with has a mobile phone? Leo recommends sharing them on YouTube. Set videos to private and then send them a link to share. That's the easiest way. Then anyone can watch it.
