# mio_video_extract_subtitles

Extract Subtitles — Extract embedded subtitles from MKV/MP4 video. Video And Audio Studio run — processes in the browser but uses more credits per run than the Document / Image / Scanner workspaces. Welcome credits cover a limited number of runs. Day Pass does not include this workspace. All three credit-based workspaces unlock with the same one-time credit pack — there is no per-workspace subscription. See mioffice.ai/pricing for current plans.

From the tool's own definition: "Tool name is 'mio_video_extract_subtitles' and description states it 'Extract[s] embedded subtitles from MKV/MP4 video' — this is a retrieval operation with no modification, deletion, or execution of arbitrary code."
