A high-resolution image is useful to pan and zoom in or out of an image (such as a scanned map or photograph). There won’t be any image degradation because you typically won’t need to zoom more than 100 percent.
Scaling video and still images up to more than 100 percent creates artifacts: individual pixels become noticeable, causing a stair-stepping effect on high-contrast diagonal lines.
Sometimes the frame size of your imported graphic doesn’t match the frame size of your edited sequence. If the frame size of the graphic is too large, only a small part of your image appears in the Canvas. If it’s too small, the background color of the Canvas (usually black) appears behind the graphic.
To scale an imported graphic to match the frame size of a sequence, use the following frame sizes:
Frame size (pixels) | Type of video |
|---|---|
1920 x 1080 | High definition, 16:9, square pixel |
1280 x 720 | High definition, 16:9, square pixel |
720 x 486 | Standard definition, 4:3, nonsquare pixel for NTSC |
720 x 480 | Standard definition DV, 4:3, nonsquare pixel for NTSC |
720 x 576 | Standard definition, 4:3, nonsquare pixel for PAL |
640 x 480 | Multimedia, 4:3, square pixel |
480 x 360 | Multimedia, 4:3, square pixel |
320 x 240 | Multimedia, 4:3, square pixel |
240 x 180 | Multimedia, 4:3, square pixel |
160 x 120 | Multimedia, 4:3, square pixel |
