In this episode, Professor Maggie Zhu and her student Zhihao Duan describe the state of the art in AI codecs and their diverse applications. AI compression can be applied to video three ways: augmenting conventional video codecs, completely replacing a conventional codec and also to compress the AI models used for various video applications. They discuss how the proliferation of lightweight video-capable devices is driving new applications and changing the balance between encoders and decoders, and how their novel architecture can beat the state of the art.

On average a 30-second video costs around $2,000 to produce. Trying to create thousands of videos at that rate can get quite costly. Wu0Hsi of Firework asked the question, what if we treated a video more like a script, that could be easily edited, modified, and templatized? This approach led them to develop a scalable solution that lets you input your content and data and let AI spit out thousands of videos for the same cost dramatically affecting the ROI of each video.Learn more about Visionular and get more information on AV1.

Thomas Davies is a Principal Codec Engineer at Visionular working on all aspects of video codec development and optimization with a special focus on RTC (real-time communications) use cases. Thomas developed the first real-time AV1 HD software video codec, for Cisco Webex, writing video enhancement algorithms, video analysis, real-time pre-filtering, and post-filtering for Webex clients and infrastructure. Thomas is a key contributor to the AV1 video codec standards development and his contributions include key codec technologies, such as entropy coding design, quantization, error resilience, and bitstream syntax.In this interview, we dive into a discussion about how RTC encoding is different from file-based streaming or live broadcast streaming. Thomas provides key insights into the main challenges around how to deal with lossy networks, low latency, low bitrates, and difficult rate control issues. We touched on methods for maintaining AV sync in software-based clients, how to optimize for minimal CPU usage, what to do with intra frames, SVC, and more. This is an episode packed with knowledge. You will want to stay to the end.Watch the full video version.Learn more about the Visionular AV1 RTC encoder.
