A more powerful eight-SDI-channel version of Lightspeed Live has been announced by Telestream. Lightspeed Live C4 includes robust support for IP inputs, and builds on the company’s introduction of an entry level dual-channel version this summer.



Telestream: The Lightspeed Live C4 server has up to 50% more encoding and processing power compared to the C3

The addition of a third model within Telestream’s Lightspeed Live family increases customer choice when addressing various applications and budgets. The new model enables remote content capture and production workflows – something that many users have requested in response to the current pandemic.

The Lightspeed Live C4 server has up to 50% more encoding and processing power when compared to the current C3 server and is capable of running Telestream’s Live Capture and Live Stream applications simultaneously across up to eight SDI channels and IP inputs of live video data.

It addresses a diversity of market applications. Lightspeed Live Capture is designed to meet the needs of production and post production teams, focused on editing and archiving content from live feed.

For these applications, the introduction of Lightspeed Live C4 offers the highest level of performance for capturing SD, HD or UHD/4K media. Live Capture C4 supports capturing from eight concurrent SD/3G-HD SDI inputs or two concurrent 4K/UHD inputs, or from several Transport/RTMP IP inputs. Live Capture C4 records in multiple video formats, including AVC-Intra, XAVC-Intra Class 100/300/480 and many more, all while simultaneously creating H.264/AVC proxy files, and storing them to a large local media RAID or to external shared storage such as a NAS or SAN.

At the same time, Lightspeed Live C4 supports Telestream’s Live Stream application, which targets live and on-demand streaming event producers and others involved in stream encoding for OTT distribution. The product of an intensive development initiative within Telestream, Lightspeed Live C4 sets new standards in UHD ABR encoding, high channel count and deep ABR ladder support – equating to more ABR encoding streams for more granular player choices in response to bandwidth fluctuation.

“Lightspeed Live C4 represents state of the art in live broadcast production. Importantly, it has the best capacity for combined Live Capture and Live Stream use cases – up to 50% higher than its C3 sibling,” commented Scott Matics, Senior Director of Product Management at Telestream. “The most powerful member of the Lightspeed Live family, Lightspeed Live C4 retains the core capability of supporting dual, redundant, synchronised streaming content delivery to CDNs in order to maximise uptime. If delivery is disrupted, there is always a synchronised, backup stream for recovery purposes.”

Lightspeed Live C4 is available globally now.
