**Enterprise- or Add-on Feature**

Stream videos straight from Kontainer to websites and webshops. Find out more and get started today. [Book a meeting with customer success](http://calendly.com/kontainer_/support).

Once the video streaming tool is activated, you are good to go. Follow the simple steps below to get a custom embed link or set up a video format template.

## Activate Video CDN

Find your video file and open it in gallery mode. Make sure the info bar on the right side of the image is open, or open it by clicking on the "i" icon in the top menu bar.

At the bottom of the info menu, you'll find the option to activate **Video CDN**.

Once you have ticked the **Activate** box, Kontainer will start converting the video file to be available in different sizes. This can take a few minutes, so feel free to get on with other tasks and refresh the window to check when the conversion is complete.\

## Embed settings

When the conversion is complete, you'll get a URL you can copy and an **Embed settings** option to customize your IFRAME or HTML embed link.

Options include:

- Autoplay
- Looped video
- Muted sound
- Hiding controls
- Sizes
- Enable download (needs to be activated before you open the **Embed settings**)

To make this quicker and easier for colleagues and external users, you can set up presets.

## Presets

Under **Resources** and **Video presets**, you can set up your own quick selection formats with the same options as the Embed settings.\

## Copy IFRAME or HTML link

When you're happy with your settings, you simply copy the IFRAME or HTML link and paste it into your website.\
 ![Copy final link within the Embed settings of Kontainer video streaming tool](https://helpdesk.kontainer.com/wp-content/uploads/2024/05/Kontainer-video-streaming_Copy-link.png)\

## Automatic subtitles & closed captions (CC)

Kontainer can automatically transcribe the spoken audio in a video and generate subtitles, so you don't have to create them manually or rely on a separate tool.

To start transcription, click the CC option and Add subtitle.

![](https://helpdesk.kontainer.com/wp-content/uploads/2026/08/Generate_Add_CC_Video_Streaming-1024x667.png)

### Language detection

The spoken language can be detected automatically, or you can select a specific language yourself before starting the transcription. There is no limit on the number of languages you can generate subtitles for.

![](https://helpdesk.kontainer.com/wp-content/uploads/2026/08/Select_Language_CC_Video_Streaming-1024x668.png)

### The CC modal

Once a transcription exists, it is managed from the CC modal. From here, you can:

1. **Translate** the transcription into other languages
2. **Edit** the transcription (text and timing)
3. **Download** the transcription as an **.srt file**
4. **Duplicate** an existing transcription
5. **Delete** the CC for any selected language

![](https://helpdesk.kontainer.com/wp-content/uploads/2026/08/CC_Options_Video_Steaming-1024x668.png)

Once transcription is complete, Kontainer automatically generates a subtitle track for the video.

![Automated CC generated in Kontainer DAM Video Streaming Tool](https://helpdesk.kontainer.com/wp-content/uploads/2026/08/CC_Example_Video_Streaming-1024x671.png)

### Uploading existing subtitles

If you already have a subtitle file for a video, you can upload it directly instead of generating a new one. Only **.srt files** are supported for upload.

![Add CC to videos with Kontainer DAM Video Streaming Tool](https://helpdesk.kontainer.com/wp-content/uploads/2026/08/Add_Existing_CC_Video_Streaming-1024x668.png)

***Note: Subtitles are not enabled by default during playback — viewers need to turn them on via the three-dot menu in the bottom-right corner of the video player.***

## Available Video Player Controls

Developers can control the video player programmatically by sending it messages via postMessage. The player can receive these messages and perform actions like play, pause, change volume, or go fullscreen — all without the user needing to click on the player itself.

This works even if the video is embedded in another page or inside an iframe.

Below, you can find a list of available controls for the Video Player:

### Playback Controls

- **Play**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'play' });`
- **Pause**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'pause' });`
- **Stop**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'stop' });`

### Audio Controls

- **Mute**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'mute' });`
- **Unmute**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'unmute' });`
- **Toggle Mute** \
   `window.postMessage({ type: 'kontainer-video-player', action: 'toggleMute' });`
- **Set Volume (0.0 – 1.0)**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'setVolume', data: { volume: 0.5 } });`

### Playback Position

- **Seek (jump to time in seconds)\**
   `window.postMessage({ type: 'kontainer-video-player', action: 'seek', data: { time: 60 } });`

### Fullscreen Controls

- **Fullscreen\**
   `window.postMessage({ type: 'kontainer-video-player', action: 'fullscreen' });`
- **Exit Fullscreen**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'exitFullscreen' });`
- **Toggle Fullscreen**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'toggleFullscreen' });`

### Video Quality

- **Set Quality**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'setQuality', data: { quality: 720 } });`

  - `0` = Auto
  - Or specific resolutions like `360`, `480`, `720`, etc.

### Targeting a Specific Player by ID

- **Send action to a specific player instance**\
   `window.postMessage({ type: 'kontainer-video-player', action: 'play', targetPlayerId: 'player_12345' });`

  Note: The playerId can be set via URL parameter ?playerId=your_custom_id or will be generated based on video source.

### Usage in iFrames

- Same commands, but post messages to the iframe’s `contentWindow`.

  Example:\
   `const iframe = document.getElementById('your-iframe-id');`

  `iframe.contentWindow.postMessage({ type: 'kontainer-video-player', action: 'play' });`
