Frequently Asked Questions
MicrocosmWorks built the server-side video export using FFmpeg and Node.js, handling high-quality rendering pipelines that process multiple video tracks, effects, transitions, and captions. The system supports export from 720p to 4K resolution with configurable bitrate and codec settings, processing hundreds of daily export requests. The architecture uses queue-based job management to handle concurrent rendering without blocking.
MicrocosmWorks developed a Python-based AI application that detects and tracks speaker faces across video frames, automatically centering and positioning the video crop to keep the subject in frame. This is particularly important for YouTube Shorts where the 9:16 vertical format requires intelligent framing decisions. The system processes face positions in real time and generates smooth panning transitions between detected faces.
MicrocosmWorks created an extensible plugin architecture in Ssemble that allows third-party integrations and custom functionality to be added without modifying core platform code. Plugins can add new effects, transitions, AI capabilities, export formats, and integrations with external services. The plugin API provides sandboxed access to the video editing canvas, timeline, and rendering pipeline with documented interfaces.
MicrocosmWorks integrated AI-powered speech-to-text transcription that automatically generates synchronized captions for uploaded videos. The system processes audio tracks through language models that support multiple languages, then overlays styled captions onto the video timeline with frame-accurate synchronization. Users can edit generated captions, choose from multiple caption styles, and adjust positioning before export.
MicrocosmWorks manages Ssemble's cloud deployments on Azure DevOps with GitLab-based CI/CD pipelines for automated testing and deployment. The infrastructure handles the compute-intensive video processing workload with auto-scaling worker nodes for FFmpeg rendering, MongoDB for project data, and CDN distribution for exported videos. The platform reliably handles hundreds of daily requests from a growing paid user base.
