MEDIASTUDIO PRO USER GUIDE276Working in different display modesIn Video Paint, you can choose to view edit windows in a number ofdifferent display modes. These modes make identifying your edits easier.They also provide a means for creating mattes and animations. There arefour display modes to select from: Normal, Onionskin, Ruby Mask, andNo Source Video, each of which can be selected by clicking their respec-tive buttons on the Standard toolbar or choosing their correspondingcommands in the View: Display Mode submenu.Normal modeNormal mode displays the contents of the active frame in the Filmstrippanel. This mode is best when you wish to see the actual frame and selectparts of it, or to use it as a reference for performing various painting andretouching tasks.Ruby Mask modeThe Ruby Mask mode is useful when you want to create a video orimage matte that protects certain areas of an underlying video from anyedits you may perform. Mattes are often used in conjunction with VideoEditor. A good example of this is a "hold-out" matte that is used to removethe matte-lines that often occur around objects which have been filmed ona blue screen background.Note:To apply the video matte, you must load it into Video Editor.A Ruby Mask works by placing a semitransparent ruby colored layer overan image. Whenever you paint on the image, you are actually removing themask, therefore revealing the underlying image. The advantage here is thatyou do not see the color of the paint as you go, which makes it easier toidentify elements in the image to either cover or remove. When youchange modes, the removed area of the mask is filled with the currentforeground color.
