Video prefiltering
| Parameter | Description | Details |
|---|---|---|
| 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. |
The cross-color processing is only visible on "rainbows" in PAL and NTSC sequences. If the video has been scaled beforehand, the filter is not efficient. That's why the cross-color processing is deactivated on HD sequences. The cross-luminance artifact is a temporal effect; it is not transformed after upscale. The filter is still efficient on HD sequences. |
| Sharpening filter | Filter applied on all output profiles with a resolution lower than the selected resolution. Used to increase image sharpness. |
|
| Spatial denoising filter | Removes noise by processing noise in the source frame by frame. |
Possible values: Off, Low, Medium, High |
| Diamond filter | Removes noise by processing noise in the source frame by frame. |
Possible values: Off, Medium, High, Adaptive |
| 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. |
TPossible values: Off, Low, Medium, High, Adaptive |

Video adjustment
| Parameter | Description |
|---|---|
| Crop overscan | Removes the input video overscan area from each edge (left, top, right and bottom). |
| 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). |
| 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. |

Video colorimetry
| Parameter | Description |
|---|---|
| Brightness, Contrast, Saturation, Temperature, Hue, Gamma | You can adjust these parameters by dragging the sliders back and forth or enter a value.Possible values: from -100 to +100 in whole digit increments.Note: A value of 0 has no effect. |

Freeze frame management
| Parameter | Description |
|---|---|
| Activate | Display a replacement image when an input freezes (due to input loss or image freeze), if this option is deactivated, then the last decoded image is displayed. |
| Type | The replacement image can be predefined or custom. |
| Image | Replacement image displayed when input freezes (due to input loss or image freeze) |
| Image URL | The path to the replacement image (GIF, PNG or JPEG file). /var/mediakind/streamsThe image URL should then be: /tmp/streams/<your-file-name>; for example, /tmp/streams/<your-file-name> |
| Insertion delay | The time between the loss of input (full stream or elementary stream) and the switch to another source. |

| Parameter | Description |
|---|---|
| Timecode | Origin of the timecode that can be inserted in the SEI (Insert timecode option is available from the Encoding tab in the Video encoding>Stream metadata settings). Choose Passthrough for the input stream timecode. |
