Setup and dependency work
VidBee
VidBee bundles yt-dlp and FFmpeg inside the desktop workflow, so the first test is usually about installer size, permissions, and whether common merge or audio tasks work without extra dependency setup.
yt-dlp GUI
yt-dlp GUI is positioned as a general desktop gui layer around yt-dlp for users avoiding the command line, so setup should be judged against that narrower product model rather than against VidBee's bundled-tool approach.
What to test
Install both tools from official sources, run one public video download, then run one higher-resolution or audio-only job that requires FFmpeg-style merging or conversion.
