A ground-up walkthrough of its hierarchical memory, latent evolution, and confidence-driven test-time optimization. 02 ·★ MEMBER·PAPER·14 min read Paper Walkthrough: Eleven Frames Are Enough — Revisiting Local Context for Long-Horizon Streaming 3D Reconstruction How do you track a camera and rebuild a scene from a video that never ends? ABot-Recon throws away long-range memory entirely and bets on the last twelve frames. A ground-up walkthrough of the paper. 03 ·Media in Production·FREE·10 min read HLS and DASH — How Video Actually Reaches You Streamed video does not flow — a player downloads small files a few seconds long, one after another. What segments and manifests really are, the arithmetic behind how a player picks a rendition, where latency comes from, how low-latency modes cheat it, and why none of it works without a CDN. 04 ·★ MEMBER·PAPER·8 min read Paper Explained: JoyAI-Video-Edit — Autoregressive Diffusion That Keeps Editing 720p Video at ~30 FPS, Without Ever Seeing the Future Say 'swap the background for snowy mountains' and the live feed comes back edited as it streams — a walkthrough of JD's JoyAI-Video-Edit from the paper itself. We trace the three-stage recipe (chunk-wise autoregression, Source-Anchored DMD, long-horizon distillation) that lets a 16B model edit 720p video at roughly 30 FPS. 05 ·Video Codecs·★ MEMBER·7 min read From H.264 to AV1 — What a Codec Generation Change Really Involves H.264 has ruled video for two decades; AV1 arrived promising royalty-free efficiency. We unpack the transition along three axes — coding efficiency, compute cost, and licensing — and end with a practical framework for deciding which codec to ship, starting from zero background. 06 ·Media in Production·★ MEMBER·9 min read Designing a Bitrate Ladder — The First Job You Get in Streaming Why one video needs several renditions. From how ABR works to rate-distortion curves per resolution and the convex hull that picks your rungs, the three ways excess bitrate costs you, how PSNR, SSIM and VMAF differ and which one decides, and per-title encoding — ending in a step-by-step procedure from choosing clips to keeping the ladder honest.
