Low Latency Multi-region Cloud Collaboration
The specific use case was centred around the creative talent in this agency being located in New York and the producer being located in Los Angeles. Our client required low-latency, frame-accurate, local representation of the content with Audio and Video in synchronisation.
The first challenge was to ensure seamless integration from on-premise edit stations to the cloud-based Virtual Machines (VMs). Using Adobe Team Project we were able to create a workflow that synced the on-premise Premiere projects to a cloud instance of Adobe Premiere. To improve performance and allow a less powerful VM to be used, only proxies were generated to the cloud.
The Virtual Machine hosts a custom network device interface (NDI) transfer application which takes an NDI signal from Premiere and securely transfers it via a peer-to-peer connection to another NDI transfer application on a machine in Los Angeles. The NDI signal is then converted to serial digital interface (SDI) using a BirdDog NDI converter. This signal is then passed to a broadcast monitor for low-latency review and approval at 1080p screen resolution.
To reduce egress costs the NDI transfer application only sends data when the non-linear editor (NLE) is playing the media, saving costs on outgoing bandwidth.
Azure Nv6 Virtual Machines
The NV-series virtual machines are powered by NVIDIA Tesla M60 GPUs and NVIDIA GRID technology for desktop accelerated applications and virtual desktops. Users are able to visualize their graphics intensive workflows on the NV instances to get superior graphics capability and additionally run single precision workloads such as encoding and rendering.
Adobe Premiere Pro is a timeline-based video editing app developed by Adobe Systems and published as part of the Adobe Creative Cloud licensing program.
NDI Streaming Protocol
Remote Monitor Server downlinks the canvas output from your Premiere or MediaComposer system and delivers it to the Remote Monitor client on your remote desktop computer. A dedicated monitor window provides you with instant high quality and very low latency video, and a local NDI Stream is also generated – to feed out to an SDI output if required.
BirdDog NDI Convertor
The BirdDog Studio SDI/HDMI to NDI Converter takes HDMI or HD-SDI signals and converts them live to NDI . It supports plug-and-play operation and can be powered via AC, DC, or Ethernet (PoE). The converter can be implemented on a device and external tally displays.
