The Transcoding Profiles screen displays all existing transcoding profiles and details about their configuration. When a profile is selected, the details of that profile are shown on the right side of the screen.
The main display includes the following data for each Transcoding Profile:
| **Parameter** | **Description** |
| --------------- | ------------------------------------------------------------------------------------------------------------------------ |
| **Name** | The name of the transcoding profile as configured in ZEN Master. |
| **Video** | The main video transcoding settings:
* Resolution
* Bitrate |
| **Video Codec** | The video codec setting selected in the profile. Options include:
* H.264
* H.265
* MPEG2 |
| **Audio** | The main audio transcoding settings:
* Bitrate |
| **Audio Codec** | The audio codec setting selected in the profile. Options include:
* AAC
* Dolby Digital Plus
* MPGA (MPEG-1 layer2) |
When you select a transcoding profile the details of the selected profile are shown on the right side of the screen.
The Details pane includes the following data for the selected profile:
| **Parameter** | **Description** |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Name** | The name of the transcoding profile. |
| **Video Codec** | The video codec that is used, e.g. H.264/AVC or H.265/HEVC. |
| **Encoding profile** | The encoding configuration type, options are:
* Main
* Baseline
* High |
| **Resolution** | The video resolution settings. |
| **FPS** | The frame rate. Frames per second. |
| **GOP** | The number of frames in a GOP (Group of Pictures) |
| **Closed GOP** | Indicates whether or not the GOP is closed. |
| **Fixed GOP** | Indicates whether or not the GOP is fixed. |
| **VBR** | Indicated whether or not Variable Bitrate was enabled. |
| **Avg. Video Bitrate** | The Average bitrate for the profile. |
| **Max. Video Bitrate** | The Maximum bitrate for the profile. |
| **Performance** | The performance of the transcoding ranging from 1 (Super Fast) to 8 (Very Slow). |
| **B Frames** | The maximal number of consecutive B frames in the GOP. |
| **Interlaced** | Indicates whether or not Interlaced video was enabled. |
| **Reference Frames** | The number of frames that can be referenced for each frame. |
| **HRD Buffer** | The length of the HRD buffer in MPEG-2. |
| **Chroma Subsampling** | The Chroma Subsampling conversion setting that was selected:
* As Source
* 4:4:4
* 4:2:2
* 4:2:0 |
| **Audio Codec** | The audio codec that was selected:
* AAC
* Dolby Digital Plus
* MPGA (MPEG-1 layer 2) |
| **Audio Profile** | The audio profile that was selected:
* *AAC Low Complexity*
* *AAC High Efficiency*
* *AAC High Efficiency v2* |
| **Audio Sampling Rate** | The audio sampling rate that was selected:
* Original
* 44.1 kHz
* 48 kHz |
| **Audio Gain** | The audio gain setting that was selected. The audio gain increases/decreases the volume of an audio PID encoded using this profile.
* Values between 0-1 means to decrease volume.
* Values > 1 means to increase volume.
* 0 - (if allowed in that screen) means mute
* 1 - no change |
