Today on the Video Verse, we have Thomas Davies, tech lead for Visionular. He will be discussing the hybrid world of video conferencing: where it started and how its use has developed over time. In addition, he'll let us in on some of the amazing changes this technology has undergone in a mere fifteen years as well as businesses slowly adapting to take full advantage of what it can offer them.

In today's episode of the video verse, we have Jan De Cock, Director of Coding Development at Synamedia, joining us to discuss the new encoder HEVC and the complexity of delivering 8K 50 Hz video to today's limited networks and devices. While quality has always been a top priority for Synamedia, they continue to make significant steps forward in optimizing their encoders and improving quality control. With a brand new statistical multiplexing algorithm ready to go, they are poised to stay ahead of the curve in the ever-changing landscape of video delivery.

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.

What variables do you need to be aware of when deciding the level of latency you need for your stream? Low and ultra-low latency is a hot topic in sports, live, poker tournaments, or online betting. Video R&D lead engineer at Evolution Gaming Behnam Kakavand, joins us to discuss some things you might want to consider as you make these decisions.

Most people have heard of VLC, but not everyone knows about VideoLAN, the parent company behind it.   Founder Jean-Baptiste Kemp shares humble beginnings by a group of university students as a non-cross-platform and non-opensource solution. 

Then we discuss other equally exciting projects that VideoLAN is currently working on.

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.

In part 2 of our sitdown with Vimeo's principal codec engineer Thomas Daede, he shares how AV1 is making 10-bit HDR the new standard for all online video. He also shares his views on the best way to evaluate the quality of an encoder, including the ever-debated VMAF scoring method. Is it the best approach, or are there other scoring systems that should be included?
