Still Picture Capture Settings Captured still images can be altered to increase their suitability for use on your PC. q Reduce Interlace Noise Movie scenes captured from digital cameras are rewritten to your hard drive at a rate of one every 1/30 second. However, the individual frames (from which you would capture a still picture) are not completely rewritten at this rate. Rather, rewriting is performed at the rate of one "half-frame" (half the number of horizontal lines or "pixels") every 1/60 second. When a computer is used to capture still pictures from movie scenes, some blurring may occur between the two halves of the one frame being captured, especially when the subject in the movie scene is moving relatively quickly. Interlacing eliminates this blur and produces a better quality still picture. In this process, however, one half of a frame is essentially preserved to "fix," or "support," the other half, thereby lowering the resolution. Therefore, we recommend you leave this box unchecked unless you plan to capture still pictures from "fast action" movie scenes, such as those taken of sporting events, etc. q Lock Aspect Ratio If your digital video camera uses the NTSC format (standard in the United States, Canada, Japan, and elsewhere) the resolution of still picture files will be 720 x 480 pixels, which is most likely slightly longer horizontally than the display of your computer. When you display these still pictures on your PC monitor, the width will be elongated when compared to its appearance on a standard-sized TV. Locking the aspect ratio, however, will compensate by reducing the image to 720 x 640 pixels, thereby preserving the originally intended size of the image. If your digital video camera uses the PAL format (standard to Australia, New Zealand, many European nations, and elsewhere), the resolution of still picture files will be 720 x 576 pixels, which is most likely slightly longer vertically than the display of your computer. If you preserve the originally intended size of the image by locking the aspect ratio, the 576 pixels will be reduced to 540, however, the resolution of image will also slightly decrease. q Crop surrounding pixels according to settings below Excess or unwanted portions around the edges of the image can be cut off. This is referred to as "cropping." Here you can enter the number of pixels you wish to have cut off from the edge of the image. Audio CD Setting
