About Russian transcription
Russian (Русский) is written in Cyrillic and spoken principally in Russia and widely across the post-Soviet states. Subtitles generated here come back in that script, as ordinary written Russian, ready to use in an SRT or VTT file.
Russian is heavily inflected, so the same word appears in many forms and a transcript will not repeat a term identically the way an English one does. That is correct, not an error, and it is worth knowing before you search a transcript for a keyword.
