MPEG-TS Settings

MPEG-TS Settings

  • Stream ID – the transport stream ID of the PAT (Program Association Table).

  • Insert Every – the time interval in seconds for a new PMT to be inserted.

  • PID – the PMT PID that will be used.

Program Clock Reference (PCR) Settings

  • Insert Every – the time interval in seconds for a new PCR to be inserted.

  • PID – the PCR PID value.

MXF OP1A Output Settings

Select the required subtype that will be used for the MXF OP1a output:

  • Generic;

  • AS03;

  • AS11.

MXF OPAtom Output Settings

MXF_OPAtom_output

For this wrapper type tick the "Use Avid folder structure" checkbox to limit the creation of media files and folders to the specified Avid folder only.

If the "Create AAF file" option is selected, the AAF file is created along with all MXF files, in the same output folder. The AAF file is regularly updated during the recording session.

Direct Transcoding

As Cinegy Capture supports the ingest from the stream sources like RTP/UDP/SRT, the direct transcoding option has been introduced to avoid re-encoding such streams if they are transmitted in the natively supported formats (MPEG2, H.264, HEVC, or Daniel2). It is very useful with an RTP input, using Cinegy Capture to ingest RTP streams from a satellite to files without re-encoding.

A new virtual encoder named "Direct Transcoding" is added to the encoders list. Additionally, a similar virtual wrapper named "Auto" is added to the wrappers list. To select direct transcoding for the ingest profile as a video track, it is necessary to choose the "Direct Transcoding" encoder together with the "Auto" wrapper. For direct transcoding mode, only PCM audio is used.

The "Auto" wrapper has the format mapping in its configuration; having pressed the "Setup" button, define which container file should be created for the specific video codec. MPEG2 and H.264 codecs allow selecting among MOV, MP4, and MXF Op1a containers, while Daniel2 and HEVC codecs support only MXF Op1a and MP4 containers respectively.

Auto_output

When the ingest session is started, the Cinegy Capture engine tries to recognize the coming stream type and creates the container file according to the format mapping. The stream will be then written to that container "as is", i.e., without transcoding.

Caution
 If no suitable encoded stream is recognized in the ingest source, the ingest session will fail.
