Adding ads or sending videos to be accepted by a copyright central are not very far away. Youtube already does this. If the video editing tool was bundled exclusively with youtube (a extreme an absurd concept I know), the examples would be instantly true. So far, I don't know of any video editing tool directly connected to youtube, but then I haven't checked on every video editing tool on iphone and android. I would be surprised if there didnt exist at least one.

Hidden watermarks already happen by printer software and some screenshot programs. Some digital cameras also do this. It not a really a big leap to say that a proprietary editing tools would/could auto-include watermarking if there was a business case for it. I would imagine that a photo editing tool bundled with getty or flickr could very easy find a business case to know when a image get posted outside its domain. Actually, there might already exist some photo-editing tools on iphone/android that do this already.
