Online converters Y2mate, SaveFrom, ssyoutube, OnlineVideoConverter Pop-up ads, redirects, quality capped at 720p, file-size limits, no batch downloads, your URL logged to ad networks Local app, zero ads, original quality (up to 最高 4K (取决于源视频)), unlimited file size, batch mode

yt-dlp command line yt-dlp, youtube-dl Most flexible option but requires terminal comfort, manual cookie handling, no GUI for batch selection Same yt-dlp under the hood, wrapped in a desktop GUI with cookie auto-detect, batch UI, and post-processing pipeline
Closed-source desktop apps 4K Video Downloader, Allavsoft, ByClick Downloader Closed-source, paid tiers gate batch and HD, no AI pipeline, no extensible Whisper / FFmpeg post-processing Open source (AGPL-3.0), AI features prepaid per-action, integrates with the rest of the ViralMint creator pipeline

Supported URL Example

Equivalent yt-dlp command

If you already use yt-dlp, the desktop app's B站 (Bilibili) download is equivalent to running:

yt-dlp -f "bv*+ba/b" --merge-output-format mp4 "https://www.bilibili.com/video/BV1xx411c7mD"

ViralMint also auto-runs Whisper transcription, downloads the thumbnail, and extracts AI hook / structure / tone insights — steps that take a separate command chain in raw yt-dlp.
