How much storage do iPhone videos take?

We're gonna be traveling in December and I'm expecting to take around 30-40min of video on my iPhone 6. It'll probably be a collection of videos from 1-5minutes long put together in an iMovie. About how much storage would this take? My phone is 64GB and I have 16.8 GB left.

Enough

It varies. There's no xxMB/min video measure, but it sounds like you should be fine with what you have left.

  • Why do my pictures take up so much storage? I have a black iPhone 5s and it's capacity is 12.1 gigabytes. I also have bought 200 gigabytes for iCloud storage. I've had my iPhone 5s for almost a year now, and my storage has been acting up lately. I've deleted most of my pictures and I now only have 35 pictures and 2 videos. The weird part- it says that my photo library takes up 10.2 gigabytes! I can't download and other apps and the only other apps that I have are Clash of Clans, PlayBuzz and Wishbone. I have no songs.
  • Why do my photos on my iPhone 4s take up so much storage? I have 455 items on my camera roll. I have about 80 videos, none go over 2 minutes. The total storage used by my 455 items on my camera roll is 8.83 gb. How do I fix this problem?
  • What to do about my iphone storage saying I'm using up way more photo storage than I actually am? My storage says I have 132 photos that's using up most of my storage; almost 3 GB. I have only 52 photos and 15 videos in my phone. It seems like it may be using storage from pictures I deleted, but apparently they're still using space? ? Has this happened to anyone else. I've taken my phone to an apple store, and I didn't get any answers.
  • On the I cloud on the Iphone what does total storage and available storage mean? Basically it says total storage 5gb and availible storage 5 gb. Does that mean there's already 5 gb of files on the Icloud?
