It's the same as sending a photo. You touch the icon on the bottom that has the arrow. It pulls up that option list asking how you want to send it such as message, email.... The hard part is that you can't send the file if it is too large. It will ask you if you want to edit video to a sendable size. Say yes and move the bars on either end to incorporate the parts that you want to send. It'll turn green (if I remember correctly) when it's within the allotted size. If its a video that you don't want to edit down (like if it's all important or you wouldn't understand what's happening if you don't send it all) then edit it to send it in segments. Send the first half then the second half or smaller chunks if it's even longer than that.
