Open Source Days 2024

NanoColor is a new addition to OpenColorIO based on work from multiple projects, people, and companies to solve a common problem - needing a "lighter" version of OCIO with a specific subset of functionality. Presenters from OCIO, USD, and MaterialX, representing companies such as Autodesk, Pixar, and Lucasfilm will talk about the design goals, development process, and scope of NanoColor, and (hopefully) have a working prototype to share. We feel that this work will be applicable to many other projects, applications, and pipelines, and are excited to continue this development.

This talk will discuss a bit how we use (and perhaps more importantly, how we don't use) AI techniques. This includes briefly exploring the boundaries of AI and what that might mean to the motion picture industry. Additionally, will talk about tooling, and open problems.

OpenEXR has reached a 25 year milestone, first created in 1999 by ILM. This talk discusses that history, and with performance engineering, security practices, and continued innovation, what the TSC is doing to ensure it survives for another 25 years. What is performance engineering? Will cover that. What are security practices? Will cover that. How does this apply to your code bases? This talk should enable that. Should you open source everything? developing a good open standard isn't a smooth road, but this will discuss the value of that

At Framestore, OpenQMC is a technology born from our desire to raise the quality and efficiency of our in-house renderer Freak. We are bringing this technology to ASWF as a sandbox project, and to the larger open source community. In this talk we will dive into how OpenQMC can be used to integrate advanced sampling techniques into pre-existing graphics applications, and the benefits this can provide. We will touch on how OpenQMC was built from the ground up with open source as a key part of its vision, and on our motivation to bringing it to the larger community. Finally, we want to let you know how to get involved, and be a voice in shaping OpenQMC moving forward.

After providing a brief update on the latest Blender development, the presentation focuses on the controversial topic of “industry adoption”. Covering topics such as project organisation and governance, the viral GPL, Blender LTS (Long Term Support), commercial support, issue triaging, open source contribution best practices and funding, the presentation aims at raising awareness about less-known aspects of the Blender project, and start meaningful conversations about adopting and investing in the popular open source DCC.

This technical presentation will dive into the development of AWS Deadline Cloud, a fully managed cloud rendering service, built in parallel with the open source Open Job Description (OJD) specification. We'll explore the architectural decisions made to integrate OJD as the foundation for defining and executing render jobs within Deadline Cloud, while ensuring OJD remained an independent open source project which could be valuable for the broader community. Attendees will gain insights into how the Deadline Cloud team worked to implement scalable and performant execution of OJD job specifications, addressing security and access management concerns specific to cloud rendering environments. Key focuses include the monitoring and orchestration solutions built atop OJD, techniques for optimizing cloud resource utilization, and lessons learned in developing a cloud service around an emerging open standard.

This presentation will showcase live how OpenRV, an open source playback software, can enable cloud-based review sessions by integrating with three streaming solutions - Colorfront, Streambox, and Ultragrid. OpenRV leverages AJA's virtual KONA card to output video in the open source Cloud Digital Interface (CDI) format for reliable transport of uncompressed video between applications to facilitate high-quality video streaming directly from the cloud. The session will cover technical details like architecture, configuration, best practices for optimizing video quality/latency, and the future potential of open source tools like OpenRV for cloud-based review workflows.

In this talk, beloFX CTO Graham explores how beloFX has implemented OpenCue in a pure cloud environment. He will provide practical insights into optimizing scaling of resources to minimize costs, as well as dealing with the complexities of managing multiple clusters in different regions. Attendees will gain an understanding of hosting a cloud-native render farm. This session offers actionable strategies for scalability and performance optimization in VFX production pipelines using Cloud services.
