Horizontal Format
Figure 26. Horizontal Format
The Horizontal Format has the following controls.
Square Pixels | Use the Square Pixels setting for normal 4:3 video (Figure 26) that is viewed | |
via a computer monitor. This setting results in a square aspect ratio sampling | ||
| ||
| of the source video and a source image of 640 x 480 for | |
| 768 x 576 for | |
|
| |
| Use the | |
monitor. This setting results in a | ||
| ||
| video. It results in a video input horizontal size of 720 pixels for both | |
| and | |
| resulting video appears horizontally stretched | |
| on a computer monitor. | |
| It is more efficient to set the horizontal mode to match the size of the output. | |
| For example, if your target video size is 640 x 480, using Square Pixel sizing in | |
| PostProcessing Mode will avoid an unnecessary software scaling step in the | |
| driver. | |
| On some systems, for reasons external to this driver, 640 x 480 video renders | |
| on screen a lot faster than 720 x 480 video – that is, the speed difference is a | |
| lot more than the 9:8 ratio of numbers of pixels. | |
