Video Encoder Settings

• BNC-1
• BNC-2
• BNC-3 (only available on Makito XR)
• BNC-4 (only available on Makito XR)

This is the input signal auto-detected from the video source. It includes the number of pixels per line, whether the video is interlaced or progressively scanned (indicated by i or p), and the number of frames per second.

Note

If the signal cannot be detected (or is outside the supported range), the Input Format will be Unknown.

Copy Protected Content DVI only

Select the Video Input type for the encoder:

Note

Automatic mode will cause increased delay during an input switch event. To reduce the re-lock delay, set the Input Type to SDI or Composite as appropriate.

Check this checkbox to enable HDCP (High-bandwidth Digital Content Protection) for the DVI interface.

• When enabled, HDCP sources will detect the Makito X as a HDCP sink. The source will decide whether or not the content it sends to the Makito X needs to be protected/encrypted. The Makito X will not encode encrypted/protected content.
• When disabled, the authentication phase where keys are exchanged will fail and the content source will detect the Makito X as a device that does not support HDCP. At this point, the source will not send any protected content to the Makito X but can still send unprotected content.
  
  

Note

Disabling HDCP will allow the Makito X to inter-work with Apple products such as the MacBook and iPad.

Select the stream output resolution (i.e., the number of lines per frame and pixels per line to be encoded):

• Automatic: Encodes at the same resolution as the incoming video.
• Manually select the coded picture resolution from the list of available options (includes down-scaled resolutions). The options depend on the Input Format detected.

Note

For supported video encoding resolutions, see Video Encoding.

This parameter crops the input and encodes to a rectangle within the input image while discarding the rest of the input image.

By default, input is scaled to the output resolution. When Cropping is enabled, the output resolution is the portion of the input that is encoded from the center. This may be done instead of downscaling.

Note

Cropping is disabled if Resolution is Automatic, 960, or 1440, or if Resolution (i.e., output resolution) is set to equal or larger than the input resolution.

Select the coded picture frame rate per second:

• Automatic: Encodes at the same frame rate as the input
• 60..1

Note

The frame rate cannot exceed the input frame rate.

Select the video compression mode for the encoded video:

• I: I frames only (lowest delay; lowest quality)
• IP: I and P frames only
• IBP: I, B and P frames (H.264 only)
• IBBP: I, BB (two B frames in sequence) and P frames (highest delay; highest quality) (H.264 only)

Note

B frames require a Main Profile decoder. B frames provide more quality as the encoding is more efficient; thus more details can be rendered in the same bandwidth/bitrate.

Tip

When B frames are used, the GOP may be rounded up to make the sequence end with a P frame.

Specifies the aspect ratio of the video source and signals it into the MPEG stream:

• Automatic: Aspect ratio is derived from the incoming video source resolution.
• Manually force aspect ratio to either: 3:2, 4:3, 5:3, 5:4, 16:9, 16:10, or 17:9.
• WSS/AFD: Aspect ratio is extracted from the incoming video source based on WSS (Wide Screen Signaling) or AFD (Active Format Description) if detected.

Note

WSS is only supported with analog PAL video; AFD is only supported with SDSDI video.

(Optional) Check this checkbox to enable Closed Captioning on the output Stream.

Note

For more information, see Closed Captioning.

Timecodes are used to mark video frames, for editing purposes or for multi-channel synchronization. This field either disables timecoding, or selects the source to “timecode” the encoded video frame. The following selections are available:

• None: No time code will be inserted in the video stream (saves bandwidth if not required).
• Video (SDI only): The timecode will be extracted from the incoming video signal.
• System: If no timecode is included in the video feed, the encoded timecode is based on the encoder’s system clock. In this case, it is is recommended to enable NTP (see Configuring Network Settings).

Note

See TimeCode Source for additional information.

(H.264 only) Select the compression scheme:

• CAVLC: Context-adaptive Variable-length Coding is a lower-complexity alternative to CABAC. CAVLC produces lower quality, but is easier to decode.
• CABAC: Context-adaptive Binary Arithmetic Coding is an algorithm to losslessly compress syntax elements in the video stream. CABAC compresses data more efficiently than CAVLC and should produce better quality, but requires considerably more processing to decode.

Note

The H.264 decoder must be Main Profile compliant or higher to decode a CABAC video stream.

Tip

CABAC provides better visual quality because it is more efficient.

(H.264 only) Check this checkbox to enable Intra-Picture Sub-Partitioning.

Intra-Partitioning is a setting that allows the use of a smaller macroblock partition during the video macroblock encoding process.

Note

Intra-Partitioning requires that the H.264 decoder be High Profile compliant.

Intra-Partitioning provides better visual quality because it gives the video encoder better coding tools.

Tip

Noisy Matrix completion is enabled automatically when Partitioning is enabled and video bitrate is under 800 Kbps. Noisy Matrix completion enhances video image “noise” reduction to improve video quality at lower bitrates and make blocky artifacts less visible.

(H.264 only) Check this checkbox to enable Intra-refresh video encoding support.

Intra-refresh is a video encoding mode of operation in which no distinct IDR frame is sent in the video elementary stream. Instead, the macro-blocks that make up the IDR frame are sent gradually within a certain time so that the entire video reference frame is rebuilt (at the decoder) within the number of frames specified by the Intra Refresh Rate parameter. Intra-refresh minimizes latency, smooths the video bitrate, and minimizes GOP pulsing artifacts.

Tip

Intra-refresh requires that the decoder and streams be started first.

(H.264 only) Specifies the number of frames over which the entire picture is refreshed. 1..5000

Note

If the refresh rate is set too low, a leftto-right wave-like artifact may result.
