Iphone 5s...will not send Videos I recorded that are any longer than 1 minut...
Email usually doesn't work for large videos. Air Drop works great. But you need to be close to who you're sending it to. I can send a 43 second video ok. But 1 minute won't work. I sent a 4 minute video to my Wife via Air Drop. Works great.
Note: This is true with any platform.
