No. Video tools use FFmpeg compiled to WebAssembly, which runs inside your browser tab. The processing engine (about 30 MB) is downloaded from this site the first time you use a video tool and then cached.
Browser-based FFmpeg runs on a single thread for maximum compatibility. Short clips process quickly; long or high-resolution videos can take several minutes.
