| What Idiot Designed This?! | Matt Szatmary | 28m |
Shows why common video oddities are historical compromises: mains power frequency (60Hz/50Hz) drives clocking so analog TV picks 30/60 and 25 families… | ||
| How to even camera | Eliot Miller | 33m |
Covers concrete how‑tos: use the rule of thirds for framing and depth, apply three-point lighting to turn grainy desk footage into a professional image, and… | ||
| Digital El Mariachi: the Beginnings of Cinema Workflows for Online Video | Tim Napoleon | 28m |
Claims that theatrical-grade workflows are now practical on small budgets, demonstrated with concrete tools and numbers: $500 gimbal to reproduce crane moves… | ||
| New video coding techniques under consideration for VP10 - the successor to VP9 | Alex Converse | 26m |
Project targets a 30–40% bit‑rate drop over VP9 but current baseline additions already yield modest gains: ~6% reported against VP9 on a large set, with… | ||
| What's in the box?! | Phil Cluff | 23m |
Shows exact MP4 internals and hands-on commands: uses Bento4 tools (mp4dump, mp4edit, mp4fragment, mp4.py), MediaInfo and hexedit to remove the ftyp and moov… | ||
| Delivering HDR | Steve Robertson | 26m |
HDR requires new delivery and mastering practices: HEVC or VP9 for delivery, most HDR sets ship as 4K, and you must use a separate transcode stack for HDR… | ||
| Decentralizing Video Streaming | Hadar Weiss | 20m |
Proposal: shift server work—transmuxing, decoding, caching, delivery—into browsers using real tools so existing CDNs serve only a few requests and peer meshes… | ||
| It's just captions, right? Why does video accessibility matter in the 21st century. | Owen Edwards | 30m |
Video accessibility matters because laws (ADA, Section 508, CVAA) and FCC metrics force real technical requirements: captions must meet completeness placement… | ||
| Other browser APIs that are going to change video on the web | Steve Heffernan | 30m |
Shows that using the fetch API returns a readable stream so segments can pipe into MediaSource with transform streams to transmux HLS TS to fMP4 in JavaScript… | ||
