We’re excited to introduce a new Live Viewers report that gives you a clearer, more immediate view into how audiences are engaging with your live streams.

This report provides near–real-time insights into live viewership over the last 24 hours, including:

• Total, peak, average, and minimum viewers.
• Rolling channel and event performance for the most recent 120 minutes.
• Viewer distribution by platform and country.
• Top channels and events by peak concurrency.

Whether you’re monitoring major events or tracking day-to-day channel trends, the Live Viewers report helps you understand where your audience is, how they’re watching, and when engagement is strongest.

You can explore the full breakdown in the Live Viewers section of the Analytics dashboard. Check out our documentation for more information, and if you have questions or feedback, our Support team is always here to help.

You asked for the ability to control your CDN delivery and we listened! We have introduced a new Multi CDN user interface to allow you to dynamically control your CDN distribution between Uplynk's default CDN and your own CDN(s) of choice.

What’s New?

• Intuitive UI: This new UI allows an easy selection of CDN distribution.
• Dynamic Control: On your live and linear streams, changes to your CDN distribution will take place in about one minute.
• Bring Your Own CDN: For increased modularity, you can now easily use your own CDN(s) with Uplynk.

Why This Matters

This feature allows you to dynamically change CDN distributions on-the-fly to balance cost, performance, or both.

Questions or Concerns?

If you are interested in using this feature, your CDN(s) need to be onboarded by us. Please reach out to our Support team - we’re here to help.

We have introduced a new API called Get Session Statistics that makes it easier to debug issues with individual playback sessions. It is especially useful for debugging HTTP 4xx errors and DRM-related errors.

More information on this new API can be found at Get Session Statistics.

We’re excited to introduce a new Audio tab on every asset, giving you more control over how your audio is organized and delivered.

What you can do

• View all audio tracks in one place.
• Add new languages or mixes.
• Update track detail.
• Replace existing audio.
• Remove tracks you no longer need (with safeguards).

Enhanced Dolby Options

You’ll also see two simple controls when adding or replacing audio:

• Dolby - Create new Dolby 5.1 and 2.0 versions.
• AC3 Pass-Through - Preserve existing Dolby audio from your source file.

Use either or both depending on your workflow.

This update makes it easier to manage multilingual and alternate audio directly in the UI. You can learn more in our documentation. If you have any questions, our Support team is happy to help.

We’re rolling out a refreshed Live Events Dashboard this Wednesday, bringing a more modern, streamlined experience to your event operations.

What’s New?

• Modernized UI: We’ve given the existing dashboard a visual and functional facelift, updating components for better usability and consistency.
• Unified Layout: All event controls are now consolidated into a single, flexible layout - no more switching across multiple tabs.
• More Flexible Structure: The new layout adapts better to different screen sizes and operator workflows, making it easier to navigate during live events.

Why This Matters

This update simplifies the day-to-day work of event operators and brings the dashboard into alignment with the UI improvements across the rest of the platform. The updated dashboard will be deployed this Wednesday (11/19).

Questions or Concerns?

If you have feedback, see anything unexpected, or need help adjusting to the new flow, please reach out to our Support team - we’re here to help.

You can now create DVB subtitles directly from your existing VTT files using Syndication.

When you add subtitles to your content on Uplynk, those subtitles are automatically converted and stored in VTT format. If you want Syndication to generate DVB subtitles from those VTT files, just include the following key/value in your Syndication job: show_vtt = 1.

For more information about Syndication, check out the documentation.

We’ve made a couple of important improvements to how you interact with tables:

• Multi-row selection: Hold down Shift and click another row above or below to select a range of rows at once.
• Keyboard navigation: Move through rows using your keyboard - press Tab to go to the next item, Shift + Tab to go back, and Space to select or deselect an item.

These updates make managing tables faster and more efficient, whether you prefer using your mouse or keyboard.

Multi-row selection

Keyboard navigation

We’ve made a small but impactful improvement to Playlists!
You can now view asset details directly by clicking on any entry in your playlist - and if you need a closer look, you can open the asset in a separate tab with a single click.

This update helps you move faster by reducing unnecessary clicks and page navigation, making it easier to manage and review your playlists.

We’ve just upgraded MP4 Exports to give you more control and flexibility! You can now export any available rendition of your asset, whether it’s high, low, or anything in between, and get direct download links for both MP4 files and any other available sidecar captions.

Whether you’re distributing content, running QA, or just need a quick download in a specific resolution, it’s now faster and easier.

Head to the Export tab of any asset to try it out.
