Marquis has enabled growing file support within its live production workflow with both LiveU Ingest and Sony C3 Portal, which will be launched at IBC 2024. Ideal for fast-turnaround news and sport programmes, the growing file support lets customers begin editing in Avid as soon as live recording starts via either the LiveU Ingest web portal or Sony C3 Portal, dramatically reducing the time required to create a final edited programme or versions for different platforms.

The novel innovation is to enable the use of chunked transport streams, which realises a 20% network efficiency over conventional file transfers. Marquis uses compute-only translation of the transport streams to OPAtoms for immediate news and sports editing.

The growing file workflow is enabled via Marquis Medway middleware, which connects LiveU Ingest or Sony C3 Portal directly with Avid. The files – complete with associated metadata – are automatically ingested directly into Avid MediaCentral or Interplay as soon as recording has started, removing the need for an expensive video server. This means an Avid editor doesn’t need to wait for the live file to finish recording before beginning the edit and is able to get finished programmes to air or social platforms as quickly as possible.

Marquis Medway is a powerful and scalable workflow software system, used globally by broadcast, production, post-production, newsrooms and playout facilities. In the new growing files workflow, Medway can see that a live recording has started from either the LiveU Ingest automatic recording system or Sony C3 Portal cloud-based content collaboration platform, then automatically begins the file transfer to Avid MediaCentral or Interplay.

An editor working in Avid Media Composer can see the live recording as a clip and import it into their sequence. As the media transfer ‘catches up’ with the live recording, the placeholder clip begins to fill up with media chunks as the stream comes in and, although the file is still growing, it is fully editable. When the live recording finishes, Medway will automatically update the clip with its final duration within Avid.

Marquis is also launching a native Avid Media Composer panel at IBC, which is now fully approved by Avid. It supports the Sony C3 Portal ingest and proxy-relinking workflow launched last year, allowing the editor to see directly into the Medway system to select and ingest any new media from the Medway watch folder, removing the need to operate a separate Medway client.
