BCut

BCut is Bilibili's video editor, with automatic captioning and access to assets and formats native to that platform.

Its value is platform fit: caption styles, cover templates and export settings match what Bilibili expects, and uploading is integrated rather than a separate step.

Its automatic captioning handles Chinese speech well, which is the feature most creators actually use it for — manual subtitling is the most time-consuming part of Chinese-language video production.
