Partial The timeline UI, effects, and export pipeline can be assembled from existing libraries like FFmpeg and whisper.cpp. A performant multitrack editor with GPU effects, codec handling, and 4K rendering is a substantial engineering effort beyond a vibe-coded prototype.
What it would actually take: Build on a media engine such as FFmpeg/libav with a GPU compositing layer (WebGPU, Direct3D, or Vulkan) and a timeline data model. Whisper.cpp or faster-whisper handles offline captions, and Arabic/Darija support needs model tuning or checking. The hard parts are real-time preview performance, frame-accurate rendering, and codec/edge-case bugs, which call for experienced multimedia or graphics engineers.
