### General

Open **Encoding Settings** for the project.

#### Encoding Activation

* **Activate Encoding&#x20;**<mark style="color:$danger;">**(Must have)**</mark>\
  Enables automatic encoding after media upload.
* **Default Source File Language**\
  Defines the language of the original audio track.

#### Subtitles and Language Processing

* **Generate Subtitles Automatically**\
  Automatically creates subtitles from the source audio.
* **Automatically Translated Subtitles**\

Under **Encoding Settings → Output Formats**, define which renditions are generated during encoding.

{% hint style="info" %}
The platform provides a **preconfigured default setup** that covers the requirements of most standard use cases. This default configuration is suitable for typical editorial, corporate, and informational video content and does not require adjustment in most scenarios.
{% endhint %}

A commonly used setup includes the following resolutions:

* 1080p
* 720p
* 480p
* 360p
* 240p

Higher resolutions such as **1440p** or **2160p** can be enabled if required, but should only be activated when necessary, as they increase encoding time, storage usage, and delivery bandwidth.

{% hint style="info" %}
**H.264** and other output formats can be combined. Mixed codec formats are created automacially and merged as combined streaming format in HLS and DASH.
{% endhint %}

**Custom Encoding Profiles**

For specialized content types, such as **sports, live recordings, or high-motion footage**, the default settings can be adapted:

* Target video bitrate can be adjusted per rendition
* Frame rates such as **50 fps or 60 fps** can be configured (We recommend to use the default setting passthrough)
* Audio bitrate, sample rate, and channel layout can be modified
* Video profile and codec settings can be fine-tuned

These options allow customers to optimize output quality for specific content characteristics while maintaining full control over resource usage and playback compatibility.

### Advanced Options

Under **Encoding Settings → Advanced Settings**:

* **CMAF Packaging (Fragmented MP4)**\
  Recommended for modern HLS and DASH delivery. (Default in the near future.)
* **Cover Creation Control**\
  Automatically generates multiple thumbnails at defined intervals.
* **Normalize Audio**\
  Optional loudness normalization.
* **Include Audio-only Version**\
  Adds an audio-only track to the streaming manifest.

### Watermark Configuration

Under **Encoding Settings → Watermark**:

1. Upload a watermark image (PNG with transparency recommended).
2. Enable **Use Watermarks**.
3. Select position and transparency level.

Watermarks are applied during encoding.

The **AI Glossary** feature allows you to improve the accuracy of automatically generated subtitles and AI-based audio processing by providing a custom pronunciation and terminology reference.

An AI glossary can be uploaded in **CSV** or **JSON** format and defines specific terms, names, abbreviations, or technical expressions, along with their intended pronunciation. This is especially useful for:

* Proper names (e.g. people, brands, locations)
* Technical terminology
* Foreign words or abbreviations
* Domain-specific vocabulary

**Uploading an AI Glossary**

To upload a glossary:

1. Open **Encoding Settings → AI Glossary**
2. Select a glossary file in **CSV** or **JSON** format
3. Specify the language the glossary applies to
4. Upload the file

Once uploaded, the glossary is automatically applied during subtitle generation and AI-driven language processing for this project.

**Supported File Formats**

**CSV format**\
Each entry consists of a term and one or more pronunciation examples.

**JSON format**\
Allows structured definitions with multiple pronunciation variants per term.

Example structures are displayed directly in the interface to ensure correct formatting.

**Scope and Behavior**

* The glossary applies **project-wide** to all newly processed media
* Existing subtitles are not retroactively updated
* Multiple glossary entries can be maintained and updated over time
* If no glossary is uploaded, standard AI language processing is used

Using an AI glossary helps ensure consistent terminology and significantly improves subtitle quality for specialized or branded content.
