I had a 3d ultrasound today and I want to put the vid on my computer, but I don't know how to get it on there. Is it locked or something? I cant just drag it onto my desktop cause it creates a short to drive E which is not what I want. Is there a free program I can use to help me with this?
Format Factory can convert it to a movie file you can save on your computer.
