About Ukrainian transcription
Ukrainian (Українська) is written in Cyrillic and spoken principally in Ukraine. Subtitles generated here come back in that script, as ordinary written Ukrainian, ready to use in an SRT or VTT file.
Ukrainian and Russian share the Cyrillic script and a good deal of vocabulary, which makes automatic detection between them unreliable on short clips. Selecting the language explicitly avoids a confidently wrong transcript.
