Viewing content is only half the story
High-quality video encoding and delivery is table stakes. Productions that need to review, discuss, annotate, and make creative decisions in real time need more than a video stream – they need a complete managed collaboration environment.
No built-in collaboration tools
A video encoder delivers the signal but doesn't provide a channel for the team conversation around it. Productions using encoder-only tools typically bolt on a separate conferencing platform – creating split-screen workflows, sync issues, and added technical complexity on both ends.
Self-managed – no specialist support
When a self-managed streaming setup fails mid-session, your team is troubleshooting alone. Streambox is a product you install and maintain – there's no 24/7 managed service team who owns the end-to-end delivery and can intervene when something goes wrong.
Public internet dependency
Streaming over public internet means your session performance is at the mercy of network conditions outside your control. On productions where real-time review consistency matters, that variability is a risk Sohonet's private network eliminates.
The complete managed remote review platform
ClearView Flex combines high-quality live streaming with the collaboration layer productions actually need, all on a managed infrastructure backed by 30 years of M&E expertise.
In-channel voice communication, on-screen annotation, and support for up to 40 simultaneous participants, all within the ClearView Flex session. No Zoom bolted on the side, no switching tools mid-review, no context lost between platforms.
ClearView Flex is a fully managed service, not a product you deploy and support yourself. Sohonet handles infrastructure setup, configuration, monitoring, and 24/7 support. When something needs attention, there's an M&E engineer on the other end of the phone.
ClearView Flex streams over Sohonet's private media network, dedicated, uncontended bandwidth optimised for M&E workflows. Ultra-low latency is consistent infrastructure performance, not public internet best-case.

"It was Disney who recommended ClearView Flex to me. Immediately, I could see that this was a game-changer. All of a sudden, we could review mixes in real time and bring everyone in on ClearView to look at material at the same time as if they were in the room."
