I have a habit of saving interesting or useful videos locally whenever I come across them, as it makes me feel more secure. Even if I add them to my "favorites," there's no guarantee that they won't suddenly be deleted or taken down. Many websites are quite closed off and don’t offer universal download options, so I use specialized tools like Seal to sniff out and download videos.
Seal adopts the Material You design and supports dynamic color extraction, making the interface both visually appealing and practical. The process of downloading videos is also very straightforward—users simply copy and paste the video link, and Seal automatically detects and extracts the video file. It offers various download formats and compatibility settings, such as saving videos as audio files, choosing download quality, downloading subtitles, and even includes a simple video editing feature.

Seal is actually built on the yt-dlp downloader, so it can be seen as a GUI wrapper for yt-dlp. In theory, any feature supported by yt-dlp is available in Seal, such as SponsorBlock segment recognition and removal, subtitle format sorting, and video thumbnail control. If certain features don't have a GUI entry, Seal also supports direct command-line calls, with detailed instructions available in the yt-dlp manual. Additionally, Seal’s settings allow users to easily update to the latest yt-dlp development version to access the newest features.

If you happen to need a tool for downloading videos on your phone, you might want to give Seal a try.
