Why Won't My Phone Allow Me to Send a Video Through Text?

Welcome to Android.
I could go on about the many things you are unable to do in iOS but you probably know the limitations. But really, take a video in full resolution on your iPhone, send it to me. Just add it to the messaging app and hit send. Like you claim there's nothing to do on your part. It will resize and format and just work right? I'd love to see what shows up on this end.
