How can I wirelessly transfer video from iPhone to Mac? I took some video on my iPhone and would like to transfer it to my Mac. However, it happens that I don't have my iPhone-to-USB cable with me today, so how I can I do it? If it was a photo I would just get it from my PhotoStream in iPhoto, but it seems videos don't appear there.

This has been asked here, but the accepted answer just says to buy an app. It's also been asked here, but the accepted answer says to email it. This doesn't work, because I get a message saying the video is too long and asking whether I want to select a shorter clip from it. (I do not.)

It seems unlikely to me that there's no way to do this with standard Apple software - so how can I do it without installing anything?

If it makes a difference I'm using Mountain Lion on a Macbook Pro and iOS 6 on an iPhone 5. I have an unlimited data plan.
I know you say you do not want to install. But you can get a free Dropbox account.

Install it on you Mac and iOS device.

Then in the iOS Dropbox. 

Tap the 3 blue circles in the Menu bar.





Select the + Upload menu.







Allow Dropbox to see you Photos if Asked.

Navigate to the camera roll or Album that contains you video.

Tap it/them to select it/them

Tap The Upload menu to upload.

Once done they should be on you Mac.
