Subtitles of the Movie
Let's create a camera. I am going to set this panel by going to panels perspective, camera one as seeing through the camera that I've just created. Now you can see that I can move the camera, and I move the camera the view here adjusts. I can use the camera controls with the mouse and the Alt button, as you are accustomed to. You must be careful though, if you are setting up the camera for animation it's easy to forget that it's not the perspective camera, and move the camera from a setting that you wanted it to be at by accident. Ok, we are going to select the camera and open up the attribute editor for the camera. You can aim your camera if you like, and here we have the various attributes of the camera which can be adjusted and controlled. Let's look in the camera one window, as I change the focal length of the camera - I am going to change it from 35 to 300. Take a look at the perspective window, we have not actually moved the camera, but we have changed the focal length, by giving the camera a longer lens. So, I am going to try and give the camera a 5mm lens. Now we've changed the view again, again the camera has not actually moved - note the distortion in the grid. I've created a very wide angle camera, and like a real camera, it has distorted the image to some extent. Ok, note the clipping plane controls, these are important when rendering – only items that occur within the clipping plane area will be rendered. In order to speed up rendering time, it can be wise to focus the clipping plane just on the area that you wish to see rendered. By focusing the clipping planes and making them smaller, it will speed up render time. Let's take a look at depth of field. You can control depth of field by turning on depth of field, this gives you the distance at which an item will be in perfect focus. The 's' stop behaves just like it does on a conventional camera. The higher the stop the deeper the depth of field, the lower the stop the less depth of field. The focus region scale, scales the focus distance. In the environment setting, you can set a background color other than black for when you render, or you can set a texture to create an environment map, when looking through or rendering with that camera. In the environment window, you also can create and apply an image plane, a tool used when modeling. Open the special effects twirly, you see that you've got control of the shutter angle. Changing the shutter angle affects the amount of motion blur that is attributed to a moving object when you’ve selected motion blur for the object in the render global windows. Let's take a look at the display options – you’ll see you can display a field chart, a traditional animation field chart, and also display the title save area, and a save action area. All tools designed to help guide when you create your motion, action or titles. You can also display the resolution that you've selected - the film gate can be displayed. You can also select journal command, this is an interesting command, in that as I described, as you move your camera, it behaves normally just like any other camera view and you cannot undo this movement of the camera, however when you turn on journal command, the undo function affects the camera. And we are going to now close the attribute editor for the camera, keep in mind when you are rendering, be certain you go to render globals and select the proper camera to render through. In this instance we would want to select camera one.
