Niconico (Nico Nico Douga) has an unusual codec mix because of its long history — newer videos are H.264/HEVC, but older ones are still in FLV or other legacy formats. GrabIt handles all of them and returns a modern playable file.
Modern uploads at source quality (up to 1080p where available).
Legacy FLV and other older formats normalized to MP4.
Both nicovideo.jp and nico.ms short links accepted.
Frequently asked — Niconico
› Do I need a Niconico account?
No — GrabIt downloads what's publicly viewable without a login. Premium-tier and restricted videos aren't supported.
› Why are older Niconico videos lower quality?
They were uploaded when Niconico capped resolution much lower than today. The downloaded file matches whatever the upload's source was.
