Hi Zeljko
Video does require specific skills, better equipment, and good software; it's not a common skill set or expense most contributors will invest in, webm is less supported even by the FLOSS community. It's not about being informed and transparent, its about having the skills, equipment, and software then sharing or making it available to the community. We also need to invest in presenting support and quality video recording using microphones, tripods, and lighting. The development of 720p through to 8k has been rapid and its been focused on mp4 not webm
While it's still at very early stages I have started asking that video editing resources be invested in if we are going to sustain hybrid events as a core part of Wikimania and other events. I have asked the Steering committee to look at support capacity as well as some of the affiliates I have volunteered with.
Most of the volunteers came from those that got scholarships as it was part of the requirement that they support the event as a volunteer in some way. Gisca is the amazing WMF staff member who supported the scholars and other attendees with travel needs, as well as volunteer roles.
