Building an Agentic Video Editor for Mass Consumer — Ekaterina Deyneka, Reelful

Aug 18, 2026 · 12:45

Ekaterina Deyneka, founder and CEO of Reelful, presents her agentic video editor as structurally identical to an agentic app builder, with editing real footage harder than generation. At Reelful, users drop in media plus a prompt, and the agent understands the media, proposes a creative plan for approval, then spins up a remote sandbox where agent skills encode cut rules, font pairings, and b-roll generation. Video is composed as React code via Remotion, a verification layer catches composition errors and sends the agent back to reiterate, and the result renders to a polished clip. To hide this complexity from consumers, Reelful is mobile-first with directional templates and a building editor for tweaks. Deyneka demonstrated clips made purely by the agent and announced Reelful's funding from a16z Speedrun.

HTML Is All Agents Need — James Russo, HeyGen

Jul 21, 2026 · 15:13

James Russo, software engineer at HeyGen, argues that HTML, CSS, and JavaScript are the native languages of LLMs and all agents need to create great videos—leading to HyperFrames, an open-source framework that turns agent-authored HTML into deterministic MP4s. By letting the small Gemini 3 Flash model author code first, they ensured the thinnest wrapper won, with only a few data attributes for timing. Rendering works by freezing the browser clock and seeking frame by frame, ensuring everything loads before capturing each frame—enabling deterministic video from any web technology (Three.js, WebGL, Lottie). HyperFrames skills focus on taste and video craft rather than teaching frameworks, raising the floor for single-shot output. The framework has already rendered over 1.3 million videos in 90 days from 267,000 creators, with 15,000 daily renders and 32,000 GitHub stars—proving the approach at scale.
