Autoscaled Video Rendering on Replit: Object Storage, Workers, and Clean Filesystems

Autoscaled video rendering works when every worker behaves like a temporary machine with a permanent contract: resolve project media from trusted storage, render inside bounded scratch space, stream the artifact to object storage, verify the result, and leave the filesystem clean for the next job.

CapCut Alternative Technical Architecture: Voice Edits, Timeline State, and Exports

A credible CapCut alternative is not only a different editing surface. It needs a durable architecture for voice commands, transcript and frame context, native timeline operations, upload recovery, media provenance, and exports that can be verified after an AI-assisted edit.
