Downloading/Sending video from my iphone to some other device in different ways
Try a peer-to-peer file transfer service to move the video directly from your phone to computer, like BitTorrent Sync. This would be faster then using a cloud solution like uploading to Dropbox or YouTube and then downloading it again. It's very simple to use too, just download the BitTorrent Sync app on your phone and Mac, turn on the Camera Roll backup feature from you phone, and then send the link to your Mac to begin the transfer. This is the probably the fastest way to transfer files with out a wired connection.
