Higher bitrate audio archives files and broadcasts The platform update includes support for 128kbps audio in MP4 archive files. This will increase bitrate of archives, allowing higher fidelity audio within recordings and broadcasts to benefit certain application use cases. See the Archiving developer guide.

AV Synchronization optimizations for composed archives and live streaming broadcasts This video platform update includes a number of optimizations to handle poor network conditions during real-time composing to improve resilience of audio/video synchronization in composed archives and live streaming broadcasts.

Longer Archive Recordings The Vonage Video Archiving API has been updated to 240 minutes, so users can archive longer meetings and video sessions (see archive duration). Automatically archived sessions will restart recording at 4-hour intervals.

New Screen share layouts for composed archives and live streaming broadcasts New screen-sharing layouts prioritize screen-sharing streams so that the user’s presentation or share always takes precedence in the archive or broadcast (see Layout types for screen sharing). Use this feature, along with the layout stream prioritization rules for composed archives and broadcasts, to make sure presentations, screen shares, and selected streams get priority in archives and broadcasts.

Increased number of audio participants composed archives and live streaming broadcasts Composed archives and live streaming broadcasts now include audio from up to 50 participants simultaneously (up from 9 streams previously). See the archiving and broadcast developer guides.

Screen share optimizations This platform update includes optimizations to prevent subscribers on poor networks from bringing down the quality of non-simulcast video streams, like screen-sharing streams, for other participants.
