Take the shot of your person and duplicate it on top of itself. (The blur feature on whatever program you use will probably be found under filters.) The trick is to use two lines of video to make one part of the image blurry and the other part not blurry. This is true for all editing software, no matter how sophisticated. If a video editing program has the capacity to blur a shot, it will blur the ENTIRE shot. When you see multiple images on the video screen, for example shots of credit cards, or words, or logos, those are small video images stacked on top of the shot of the person speaking.Īnyway….to blur the background behind people takes two lines of video. The more complex the program, the more lines of video and audio you have available to you. When you are editing video, the process is to stack video and audio elements onto lines inside what is called a timeline. WMM is a limited program and you could not do this technique in WMM. The timeline is the bottom portion of the screen. Here is an example of Windows Movie Maker. First, here is some quick background on video editing basics to make sure you understand what I am about to talk about. This is considered an advanced editing technique. If you want to blur the background while EDITING, it takes a video program that has at least 2 lines of video. In short, as the videographer, you need to create the proper circumstances to make the background appear out of focus. Tripods are essential when using a telephoto lens. One of the characteristics of a long lens is that camera shake is magnified. Whenever you are using your long lens zoomed in, make sure and use a tripod, otherwise the shot will look shaky. The more you zoom in, the more shallow your depth of field becomes. Then you have plenty of room to zoom in as much as possible. It’s best to have the camera back about ten feet away from the subject. In order to use your long lens, you will need a bit of room. The blurry background on the baby picture is just a few inches. With an extremely shallow depth of field, you could get away with MUCH LESS space than that. ![]() With a shallow depth of field, this much distance will ensure that the background will be out of focus naturally. On top of this, select a location where can have about five to ten feet of space between your subject and the background. But soft, diffused light, about the quantity you’d want in a fairly well-lit living room will produce the results I am talking about. Of course you can’t go TOO low with your light or the picture will not look good. So you combine the two techniques for the most dramatic results. Low light also gives you a shallow d-o-f. A long lens automatically gives you shallow depth of field. If your video camera has a zoom lens, then it is in the “long” position (telephoto) when it is zoomed all the way IN. To get a shallow depth of field, shoot using a long lens in fairly low light. Basically depth-of-field boils down to how much of your shot is in focus from front to back. If you would like to read more about the basic concept of depth-of-field, you can read some background information by clicking here. ![]() In other words you want everything BUT the subject matter out of focus. Just like the baby picture above, you want a SHALLOW depth of field.
