Description: The VP9 codec is at an interesting inflection point. On the one hand, VP9 provides better quality than H.264, and similar quality but much better browser support than HEVC. On the other, AV1 plays in most of the same browsers as VP9, though AV1's encoding times are much, much longer, and AV1 doesn't (yet) share VP9's support in the installed base of SmartTV and OTT boxes.

Interest in VP9 production seems high. In the Bitmovin 2020 Video Developer Report, 12% of respondents already supported VP9, and 18% planned to add VP9 support in 2021. VP9-related articles on the Streaming Learning Center are pulling plenty of viewers. This webinar will help producers ascertain VP9's viability and optimal implementation options.

Specifically, the webinar starts by presenting how VP9 compares to H.264, HEVC, and AV1 quality and performance-wise. Then it reviews options for live encoding and transcoding and VOD encoding. It concludes with a look at the most relevant compatibility and quality-related VP9 configuration options and provides an optimized FFmpeg command string for live and VOD encoding.
