Input parameters
Video
Video selection and media processing parameters are used for video pre-filtering, video adjustment and video colorimetry.
Video pre-filtering
| Parameter | Description |
|---|---|
| Deblocking filter | Remove the MPEG2 blocking artifacts. This filter is fully automated to remove the blocking and ringing effects. |
| Cross-talk filter | Remove noise by processing noise in the source frame by frame. Also reduces crosscolor and crossluminance artifacts remaining in the input video. |
| Spatial denoising filter | Remove noise by processing noise in the source frame by frame. |
| Diamond filter | Remove noise by processing noise in the source frame by frame. In Adaptive mode, adapts the filtering strength and uses both edges and noise detection filters to choose areas to filter. |
| MCTF | Remove noise by processing noise in the source with a temporal factor. Has a 7 frame rolling window. In Adaptive mode a noise detection filter adapts the filter strength. |
Video adjustment
| Parameter | Description |
|---|---|
| Crop overscan | Remove the input video overscan area from each edge (left, top, right and bottom). |
| Adaptive inverse telecine | Select to detect 30/60fps telecine contents and convert them to 24fps. |
| Aspect ratio | Select the Auto option to passthrough from WSS and AFD information, or force to a specific ratio. |
| Noise edge removal | Number of lines removed from the top of the video (up to 6 in SD and 14 in HD). |
Video colorimetry
| Parameter | Description |
|---|---|
| Brightness | Define the content's relative lightness or darkness. Possible values: From 100 to 100 |
| Contrast | Define the separation between the darkest and brightest areas. Possible values: From 100 to 100 |
| Saturation | Saturation increases the separation between colors, whereas contrast increases the separation between shadows and highlights. Possible values: From 100 to 100 |
| Temperature | Define a color's perceived warmth or coolness. Possible values: From 100 to 100 |
| Hue | Define a color's perceived purity. Possible values: From 100 to 100 |
| Gamma | Increase Gamma to make an image look brighter. However, being nonlinear, this only increases brightness of the shadows and midtones in an image, without affecting the highlights. Possible values: From 100 to 100 |
Closed Caption
| Parameter | Description |
|---|---|
| Select | Select the Closed Caption tracks to include in the output. The tracks can be added by generating a TTML file in output. |
| Language | Specify the language for the Closed Caption track. Entries must comply with ISO 639_2 language standards. One entry per track. |
| Track ID | The number assigned to a Closed Caption track used to identify the track. |
Audio
Selection
| Parameter | Description |
|---|---|
| Selection | The encoder selects the first track that matches the defined codec and language criteria. |
| Codec | Set your codec selection criteria. You can select multiple codecs and order them using drag and drop. The first codec to match the selection in the defined order is used. Use any to match with any codec. |
| Language | Set your language selection criteria using the ISO6392 format. You can select multiple languages and order them using drag and drop. The first language to match the selection in the defined order is used. Use any to match with any language. |
| PID | Enter PID(s) and validate using the space bar. The first PID to match the selection in the defined order is used. Use 'any' to match with any PID. A PID is a number between 16 and 8190 |
Audio processing
| Parameter | Description |
|---|---|
| Default language | Default language is used when there is no language specified on the ingested stream. Use ISO6392 format. |
| Gain | Amplify or attenuate the incoming signal Possible values: From 100 to 20 |
| Target loudness | Maintain the audio level at the level defined by the Target loudness parameter. Loudness refers to the perceived strength of a piece of audio (music, speech, sound effects, etc.). It is defined by International Telecommunication Union in ITU-R BS.1770. The result is a value expressed in either LKFS (Loudness K weighted Full Scale). Loudness can be measured on mono, stereo and 5.1 audio signals. In the case of 5.1 audio signals, the five main channels (left, center, right, left surround and right surround) are considered. The LFE (low frequency effects) channel is excluded from the measurement. Loudness measurement is done in several steps. On-Demand Encoder algorithm: The loudness level of the first minute of the asset is measured before actual encoding. The measured value is used to initiate the algorithm and correctly adjust loudness at the very beginning of assets or for short assets. Then the algorithm regularly measures and adjusts the loudness all along the asset to keep the target level. Note: For more information, refer to the dedicated Technical Note, "Target Loudness Management". |
| Audio delay | Adjust the delay between audio and video. Example: helps resolve lip sync issues. Possible valuesFrom 300 to 300 |
| Downmix channels compression mode | Select a mode for Dolby input stream downmixing from 5.1 to stereo. |
Subtitle
Selection
| Parameter | Description |
|---|---|
| Type | Select the subtitle based on its stream type. |
Subtitle processing
| Parameter | Description |
|---|---|
| Default language | Enter a language according to ISO6392 language standards. This language is used to specify the subtitle track language. The specified language will be defined as default if no default language have been defined in the input files.Note: Click the Force language button to set the specified language as default over the default language defined in the input files. |
| Default language | Enter a language according to ISO6392 language standards. This language is used to specify the subtitle track language. |
| Filename pattern | The file pattern is relative to the input file directory. Following file pattern are supported: {inputFileName}. |
| Delay | Delay from video start time in ms. |
| Charset | Optional, default 'auto'. Only SRT, it could be used to force file decoding method to 'ansi' or 'utf8'. In case of 'auto', worker will try to autodetect file encoding or otherwise use 'ansi'. |
Metadata
Selection
| Parameter | Description |
|---|---|
| Type | Select the metadata based on its stream type. |
Teletext processing
| Parameter | Description |
|---|---|
| Max bit rate | Set the max bit rate of the teletext stream. When under estimated, some underflow may appear in the output, resulting in a job failure with an explicit message. |
SCTE-35 processing
| Parameter | Description |
|---|---|
| Source | Select the appropriate source for SCTE35. It can be outofband (provided through job metadata) or inband (provided by the asset itself, through an embedded SCTE35 track). |
