Sharp Motion | The Sharp Motion option makes detail in motion areas sharper, but at |
| the expense of somewhat jagged diagonal edges. |
|
|
Test Mode | The Test Mode option causes the motion adaptive algorithm to enter a |
| test mode that displays motion pixels as bright green dots. The dots are |
| mainly along edges that are in motion, but if the motion threshold is set |
| too high there may also be a random distribution of green dots caused |
| by pixel jitter and instability of the video signal. The extensiveness of the |
| green areas vary according to the settings of the other adjust controls. |
| Test mode is always automatically exited when you exit the Adjust |
| dialog. |
| In Test Mode, with the Sharp algorithm green speckles are on alternate |
| lines only, and with the Smooth algorithm they are on all lines. |

∙If your video format results in exact 2:1 or 4:1 vertical scaling for a particular pin, then all the video comes from one field. This is the case for uncropped NTSC CIF (320x240) or QCIF (160
x120). It may be the case for special cases of cropped video as well.
∙In the PostProcessing sequence as currently implemented, the sharp motion adaptive deinterlacing algorithm has no effect on
adetectable blurring effect on areas of motion. (Sharp and smooth are set in the Adjusts subdialog.)
∙Inverse telecine, if enabled, does not affect the individual fields for a
∙When Auto mode is selected, some kinds of content cause the driver to frequently switch between Inverse Telecine and Motion Adaptive processing. Content such as title sequences and commercials are often telecine, but cuts between scenes generally break the telecine sequence, forcing the driver to resynchronize. It takes it a number of frames to lock on to the new sequence. The driver drops back to the Motion Adaptive algorithm as soon as it becomes aware that telecine sync has been lost. However, it may take it several frames to discover that this has happened; these frames are not correctly deinterlaced.
∙You should decide whether to use Auto, Inverse Telecine, or Motion Adaptive mode depending on the type of content you expect.
∙ If the content is consistently telecine, then either Auto or Inverse Telecine is recommended for perfect recovery of the original progressive format.
∙ If the content is telecine with
