If a video is less than 45 minutes, you can plug it into any gemini and have it transcribe and diarize the video. (although, I've been told it only works on aistudio anymore) Sometimes it trips up. However, plugging in videos longer than 45 minutes quickly leads to ludicrous behavior the longer it is over 45 minutes.
You can even just plug in the Youtube link with a short prompt.
Bear in mind that thinking that plugging in the transcripts will help the Gemini model in any way frequently results in mistranscriptions being included and actually compromises the diarizations.
The prompt I use is...
"Please transcribe, diarize, and speaker identify the speakers from the Youtube video."
Another thing I've learned is that long-worded prompts also interfere with the results in weird ways.
