Coactive.ai helps businesses analyze unstructured image and video data to extract insights. The platform connects to clients' visual data via a secure data lake connection or by uploading images and videos through an API. Once connected, users can run queries in SQL and with familiar big data tools to extract insights without needing deep technical expertise. It addresses the lack of metadata by using data-centric AI and high-performance deep learning to generate accurate metadata for visual data. The product differentiates itself by enabling SQL-style querying over unstructured visual data and metadata, making it accessible to data practitioners and teams who rely on visual information. Coactive’s goal is to empower organizations to turn visual data into actionable insights at scale, typically through a subscription or usage-based pricing model.

NAB 2026: Mimir to highlight latest platform evolutions.

NAB 2026: Mimir to highlight latest platform evolutions. Mimir will offer attendees as NAB 2026 a walkthrough of what an actual serverless production workflow looks like. Mimir Cutter brings everyday editing of broadcast-quality clips to the cloud platform where the media already lives. Developed to help teams do more with less time, less effort, and less faff, it eliminates the 'download-open-export-reupload' relay race and enables ingest-to-publish with fewer tools, fewer handoffs, and less waiting. With Mimir Cutter, teams can quickly reframe content for different outputs (9:16, 1:1, 4:3) with pre-sets and keyframing, so that the focus stays consistent across versions without rebuilding the same story in multiple timelines. Users can also detach video and audio when independent control is needed, then work faster with improved multi-track handling and clearer visibility (waveforms, level metering, and keyframes). When the sequence is ready, teams can render directly from Mimir Cutter using admin-defined export presets, so finishing and delivery do not require bouncing out to another system for straightforward jobs. When a project needs full desktop finishing for colour, advanced audio mix, or effects, the cut can be picked up and finished in DaVinci Resolve and Adobe Premiere Pro. Since its inception, Mimir has offered agnostic access to some of the most powerful media AI services on the market. Users can choose which LLM, transcription, translation, or recognition service to work with to generate metadata, summaries, and tags. Agnostic semantic search was a natural evolution of this philosophy, and now the same easy-access workflow is available in Mimir for agentic search. Mimir integrates with leading AI-driven video discovery platforms like AWS, Google, TwelveLabs, and CoActive AI that analyse footage at scale to make it searchable by what's happening on-screen and in the audio, including who appears, what's said, and key moments and reactions. Mimir uses those signals to automatically surface the right moments with edit-ready segments in Mimir Cutter, so users can refine and publish immediately. In news, that can mean searching a press conference for "every moment the spokesperson appears," or "the point where they share the new guidance," and jumping straight to the exact soundbite and shot needed, already ready to clip. In sports, it means going beyond the play to the moments that make highlights travel - the face right after the whistle, the crowd eruption, or the heartbreak of a missed shot - and moving those moments straight into a cut to finish fast. Mimir is AI vendor-agnostic, so teams can keep their preferred intelligence stack while standardising the search-to-edit workflow in Mimir. Ingest should not be the step that slows everything else down. Mimir's mobile app adds ingest so trusted contributors can capture and send high-quality video directly into Mimir, dramatically shortening the time between camera and production. This builds on Mimir's existing upload-link workflows with a field-first experience designed for real conditions: when using the app, uploads can continue in the background, recover from unstable connectivity, and prioritise quality so teams get usable footage even when the network is not perfect. As content arrives, a lightweight proxy is made available quickly so producers and editors can start reviewing and cutting sooner, while the full-quality master continues uploading. The result is faster time-to-air, fewer ingest bottlenecks, and a wider network of reliable on-the-ground sources, including external contributors when needed. Mimir also brings US closed caption handling into the core workflow so teams can maintain existing captions as edits happen, instead of exporting to a separate system, fixing, and reimporting every time the cut changes. This matters in fast-turnaround workflows, including live ingest and MXF-based production, where speed and format requirements leave little room for extra caption passes. The result is less busywork and fewer failure points, with accessibility and compliance handled as part of production rather than a last-minute scramble that slows publishing down. Sharing.
