Sean is looking to get a video camera for private investigations work. He needs a camera that will "burn" the time/date stamp on the video itself as opposed to only being able to see that time/date stamp in the viewfinder.
Leo says that used to be a popular feature, but people have complained because they don't remember to turn it off. So it's fallen away as a feature in most video cameras. In that case, Sean may need a program that will read the meta data from the video and burn it into the image while importing to the PC. Final Cut Pro and Adobe Premiere both support this.
