The challenge of video editing, often perceived as tedious and manual, is a significant barrier for many content creators. Ekaterina Deyneka, founder and CEO of Reelful, addressed this issue at the AI Engineering World's Fair, introducing Reelful's approach to agentic video editing. The core problem, as Deyneka highlighted, is that while individuals capture a wealth of photos and videos during events and trips, the effort required for editing often prevents this content from being shared online.

The Concept of agentic video editing

Deyneka defined agentic video editing as a process where AI agents handle the transformation of raw footage into ready-to-share clips. Users simply provide their media and context, such as what happened in the footage or specific editing instructions like adding captions, music, or voiceovers. The AI agent then understands the media, identifies key moments, assembles the content, generates necessary elements like captions and music, and produces a polished final product. An example provided was an agent capable of cleaning up speak-to-camera videos by removing pauses and unsuccessful shots.

Reelful's Infrastructure and Approach

From an infrastructure perspective, Deyneka drew parallels between agentic video editors and agentic app builders. Both involve a user prompt (media plus prompt for video editing), a backend agent with tools and skills operating in a sandbox environment, and a final output (rendered video or app preview). However, Reelful differentiates itself by focusing on editing existing footage rather than generating new content. This, Deyneka explained, presents a more complex challenge as the agent must intelligently select and arrange real-world moments, even from messy or incomplete footage, to produce a professional result that is indistinguishable from human-edited content.

The Reelful workflow begins with media understanding, including transcription of speech. A creative plan is then generated for user approval before the editing process commences. This plan is executed within a remote sandbox environment where the agent utilizes various skills, such as cut rules, font pairing, B-roll generation, music composition, voiceover generation, and image animation.

Simplifying for Mass Consumers

Recognizing the complexity of this agentic workflow, Reelful aims to make it accessible to a broad audience. Their strategy includes a mobile-first design, enabling users to edit on the go. They are also implementing directional templates for common video types (e.g., speak-to-camera, B-roll additions) to simplify the prompting process. Furthermore, the inclusion of a built-in editor allows users to fine-tune the AI-generated output, offering a familiar editing experience for those accustomed to traditional tools.

Deyneka showcased examples of videos created with Reelful, emphasizing that they were assembled entirely by the agent without manual editing. She also announced that Reelful is offering beta access to its second version and invited feedback from the community. The company recently secured funding from A16Z Speedrun, signaling confidence in their vision for democratizing video editing.
