VideoCap: AI動画ジェネレーター

MicrocosmWorks built VideoCap's AI pipeline using machine learning models that analyze input text or images, select appropriate video templates, generate scene transitions, and compose the final output using FFmpeg. The Flutter-based mobile app handles the UI while compute-intensive video rendering runs on cloud functions, allowing users to create professional videos in minutes without desktop editing software.

MicrocosmWorks implemented a comprehensive FFmpeg pipeline in VideoCap supporting multi-track video composition, animated text overlays, image-to-video conversion, audio mixing, resolution scaling for social media formats (9:16, 16:9, 1:1), and hardware-accelerated encoding. The pipeline handles concurrent rendering jobs through a Node.js queue system that distributes processing across available cloud resources.

MicrocosmWorks built VideoCap using Flutter, enabling a single Dart codebase to target both iOS and Android with native performance. Platform-specific features like camera access, file storage, and push notifications use Flutter platform channels that bridge to native APIs. This approach reduced development time by approximately 40% compared to building separate native apps while maintaining a consistent user experience.

MicrocosmWorks designed VideoCap to offload heavy video processing to cloud functions while the mobile app handles lightweight preview generation locally. Video uploads use chunked transfer with resume capability for unreliable connections, and rendered outputs are streamed back to the device or stored in cloud storage with shareable links. The app intelligently manages local cache to avoid filling device storage.

MicrocosmWorks integrated AI/ML models for scene understanding, text-to-visual matching, and automated editing decisions in VideoCap. The models analyze input content to determine optimal video structure, pacing, and visual elements, then generate a composition script that the FFmpeg pipeline executes. This approach allows non-technical users to create engaging videos without manual editing at MicrocosmWorks development rates starting from $20/hr.
