Paper Walkthrough — Beyond Retrieval: LatentStream Turns Retrieved Video Into Latent Memory
For never-ending video streams, LatentStream stops appending retrieved evidence as extra context and instead internalizes it into fixed-length latent memory tokens. A ground-up walkthrough of its hierarchical memory, latent evolution, and confidence-driven test-time optimization.

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.

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.

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.

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.

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.
