34 Chapter 4: Projects See "Trimming Files" on page 42 for more information on setting the In/Out points. Below the In and Out indicators, the duration of the source movie and the current frame time are shown. The time format is: hours:minutes:seconds:milliseconds. This differs from normal SMPTE time code, which specifies the frame, not milliseconds of the current time. See "The Cleaner Time System" on page 43. The Source File Tab The first tab in the Project window displays the source video information, the Display aspect ratio, the Crop aspect ratio, and the Frame Format pulldown menus, as well as the source audio information. The name of the tab indicates the method used to read the source file. Aspect Ratio Correction Some formats, such as DV, do not have square pixels and must be corrected to look normal on a computer screen. Cleaner automatically does this by default for DV and other common sources, but you can manually change the aspect correction applied to the source file by using the Display aspect ratio pop-up menu in the Project window. Note: Changing the display aspect ratio does not alter the final file in any way. It merely changes how it is displayed within Cleaner. Sometimes, you may want to set a specific aspect ratio correction to compensate for unusual source material. The Display aspect ratio pop-up menu in the Project window enables you to adjust how Cleaner displays the file and can help you see how the image will look when displayed on a television screen or monitor. This makes cropping easier by allowing you to accurately determine which parts of the image you want cropped. To manually control aspect ratio correction: Choose one of the following display aspect ratio options from the Display aspect ratio pulldown menu. • raw pixels - 1:1 square pixel aspect ratio. • 4:3 - Standard NTSC/PAL aspect ratio. • 16:9 - Standard HDTV aspect ratio.
