Uses your browser's own built-in encoder directly — works even if every CDN is blocked on this network. Supported in Chrome, Edge, and Safari; not supported in Firefox.
ProRes / 8K run a real software encoder compiled to WebAssembly, entirely in your browser. They're slow and memory-hungry — try a lower resolution first if it stalls.
Codec export loads the encoder from ./vendor/ffmpeg-core/ if present, otherwise a public CDN. Needs http(s):// hosting.
