The system uses media understanding, a creative plan for user approval, a sandboxed agent environment with skills (cut rules, font pairing, B-roll generation), sub-agents for music/voiceover generation, Remotion (an open-source React-based video framework) for composition, and a verification layer to catch rendering errors. The product is mobile-first, offers directional templates for users who don't want to prompt, and includes a manual editor for tweaks. The company recently received funding from a16z's Speedrun program. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How does an agentic video editor use Remotion to generate videos? An agent writes React code using Remotion, an open-source framework for creating videos as code, to assemble tracks, assets, and timing into a video composition. Agents are effective at writing code, so this composition step lets them programmatically define cuts, captions, music, and B-rolls before rendering, with a verification layer checking the output before final render. _Anyone comparing agentic tooling approaches for AI video products can track these architecture patterns on daily.dev._ ### What is the difference between an agentic app builder and an agentic video editor architecture? Both spin up a remote sandbox machine where an agent with tools and skills works on a prompt, but the artifact differs: an app builder produces a codebase and an app preview, while a video editor produces a video composition and a rendered video. The video editing case is considered more complex because the agent must select the best moments from real footage rather than generate from a blank canvas. _Developers designing agent sandboxes for creative tools can follow these infrastructure comparisons on daily.dev._ ## Similar posts on daily.dev - [Reelful’s AI turns your camera roll into short-form videos for social media](https://daily.dev/posts/reelful-s-ai-turns-your-camera-roll-into-short-form-videos-for-social-media-aszqmkwdy) · TechCrunch · 0 upvotes · 0 comments - [How we built a free video editor that never uploads your files](https://daily.dev/posts/how-we-built-a-free-video-editor-that-never-uploads-your-files-iog9cmrlm) · Medium · 17 upvotes · 1 comments - [Agentic Video Editor](https://daily.dev/posts/agentic-video-editor-7ovgrzfy7) · Hacker News · 1 upvotes · 0 comments --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents) [View this post on daily.dev](https://daily.dev/posts/building-an-agentic-video-editor-for-mass-consumer-ekaterina-deyneka-reelful-zje2ilkhm) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Building an Agentic Video Editor for Mass Consumer — Ekaterina Deyneka, Reelful","url":"https://daily.dev/posts/building-an-agentic-video-editor-for-mass-consumer-ekaterina-deyneka-reelful-zje2ilkhm","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/building-an-agentic-video-editor-for-mass-consumer-ekaterina-deyneka-reelful-zje2ilkhm"},"datePublished":"2026-08-18T14:50:08.404Z","dateModified":"2026-08-18T14:50:30.321Z","description":"A founder talk describes building Reelful, an agentic video editor that lets consumers drop in raw media and a prompt to get a polished, ready-to-share clip....","image":"https://i.ytimg.com/vi/pPj_tjlvYjA/sddefault.jpg","thumbnailUrl":"https://i.ytimg.com/vi/pPj_tjlvYjA/sddefault.jpg","isAccessibleForFree":true,"articleSection":"AI Engineer","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"AI Engineer","logo":"https://media.daily.dev/image/upload/s--u5PucxNT--/f_auto/v1724338940/logos/aidotengineer","url":"https://daily.dev/sources/aidotengineer"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/building-an-agentic-video-editor-for-mass-consumer-ekaterina-deyneka-reelful-zje2ilkhm","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents","timeRequired":"PT12M","video":{"@type":"VideoObject","name":"Building an Agentic Video Editor for Mass Consumer — Ekaterina Deyneka, Reelful","description":"A founder talk describes building Reelful, an agentic video editor that lets consumers drop in raw media and a prompt to get a polished, ready-to-share clip....","thumbnailUrl":"https://i.ytimg.com/vi/pPj_tjlvYjA/sddefault.jpg","uploadDate":"2026-08-18T14:50:08.404Z","duration":"PT12M","url":"https://api.daily.dev/r/zJe2ILkhM","embedUrl":"https://www.youtube.com/embed/pPj_tjlvYjA"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"AI Engineer","item":"https://daily.dev/sources/aidotengineer"},{"@type":"ListItem","position":3,"name":"Building an Agentic Video Editor for Mass Consumer — Ekaterina Deyneka, Reelful"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/building-an-agentic-video-editor-for-mass-consumer-ekaterina-deyneka-reelful-zje2ilkhm#faq","mainEntity":[{"@type":"Question","name":"How does an agentic video editor use Remotion to generate videos?","acceptedAnswer":{"@type":"Answer","text":"An agent writes React code using Remotion, an open-source framework for creating videos as code, to assemble tracks, assets, and timing into a video composition.
