Video processing
Video prefiltering
| Parameter | Description |
|---|---|
| Deblocking filter | Removes the MPEG2 blocking artifacts. This filter is fully automated to remove the blocking and ringing effects. |
| Cross-talk filter | Removes noise by processing noise in the source frame by frame. If activated, reduces crosscolor and crossluminance artifacts remaining in the input video. |
| Sharpening filter | Filter applied on all output profiles with a resolution lower than the selected resolution. Used to increase image sharpness. Example: Enhance text readability on lower resolutions. |
| Spatial denoising filter | Removes noise by processing noise in the source frame by frame. |
| Diamond filter | Removes noise by processing noise in the source frame by frame. The adaptive mode uses both edges and noise detection filters to choose the areas to filter, and to adapt the filtering strength. |
| MCTF | Removes noise by processing noise in the source with a temporal factor. Has a 7 frame rolling window. The 'Adaptive' mode uses a noise detection filter to adapt the filter strength. |

Video adjustment
| Parameter | Description |
|---|---|
| Crop overscan | Removes the input video overscan area from each edge (left, top, right and bottom). |
| Adaptive inverse telecine | NTSC content is encoded at 30 fps unless the filter is selected. |
| Frame rate conversion | You can convert the frame rate from PAL to NTSC or NTSC to PAL.Video frame rate can be converted from PAL to NTSC (25i to 29.97i / 50p to 59.94p) or NTSC to PAL (29.97i to 25i / 59.94p to 50p).<br>Subtitles, closed captions or timecode are not converted. |
| Aspect ratio | Aspect ratio can be passthrough from WSS and AFD information. You can also override/force the aspect ratio to 16/9 or 4/3. Possible values: Auto, Force 16/9, Force 4/3 Note: See Picture aspect ratio handling (Auto) for more information. |
| Noise edge removal | Number of lines removed from the top of the video (up to 6 in SD and 14 in HD) Possible values: From 0 to 6 for SD, from 0 to 14 for HD Note: 0 means no adjustment. |
