Video Preprocessing Filters
Instant DVD includes video preprocessing lters which provide the ability to remove some of the noise found on old
video tapes, TV reception or other noisy video sources.
Spatial Filtering
This refers to ltering pixel data that are all located in the same video frame. The Spatial lter is a low-pass lter.
This lter removes part of the high frequency noise components. Too much ltering can reduce image sharpness to
the point of looking very smooth or blurry. The selection range for this lter is from 0 to 7.
Temporal Filter
This lter processes pixel data that are located in the same pixel coordinates but across two frames of video, usually
the current video frame and the previous frame. Because of motion in video sequences, and object located in one
position may have moved in the next video frame. Thus, if there is a log of motion, temporal ltering may cause
blurring or introduce other artifacts. The selection range for this lter is from 0 to 255.
What is the best lter to use for your video? There is no magic formula, you will need to experiment with different lter
settings and pick the lter level that removes noise but does not create blur.
Use Deinterlacing (Preview/Playback)
The MPEG-2 software playback codec that we use does not de-interlace video by default. Interlaced video will show
horizontal lines when you preview or playback the video. This interlacing does not affect video quality. All NTSC and
PAL video is interlaced. You will not see the interlacing when playing back a DVD disk on TV.
De-interlacing the video during preview and playback makes the video quality look better on the computer screen.
The default capture settings have de-interlacing turned on by default. De-interlacing the video takes a bit more CPU
processing power. Some slower PC’s may experience jerky video. In the custom settings, you have the ability to
enable or disable de-interlacing. Experiment with your system and your personal preferences to determine if you
want to preview with de-interlacing enabled or disabled.
