Now you are all ready to go. Just remember that changing to the 4K format in settings will keep this feature live when you come to record. If you want to change to another format, you'll need to go back into settings and update accordingly. This may not be a problem if you purchased the 64GB, or 128GB models, but if you go for the 16GB it could be. Recording footage using the default 1080p setting will use around 200MB for every 60 seconds of film captured, whereas 4K will consume almost double that, a whopping 375MB.
