Video URL to ASS FAQs

Why use ASS over SRT?+

ASS supports per-line styling, positioning, and speaker tags in the Name field — important for karaoke, anime fansubs, and multi-character dialogue.

Are speaker names written into the ASS file?+

Yes. Each Dialogue line carries the diarized speaker name in the Name field, so Aegisub and mpv can colour or filter by speaker without extra setup.

Can I open the file directly in Aegisub?+

Yes. The export uses V4+ styles with sensible defaults (Arial 52, white fill, dark outline) so it loads cleanly into Aegisub with no warnings.

Does the extractor support YouTube and Drive URLs?+

Yes. We resolve YouTube, Vimeo, Drive, Dropbox, S3, and direct .mp4 links automatically — no download required.
