YouTube's terms do not allow downloading its videos, so Muvero does not take YouTube links. For a video of your own, download it from YouTube Studio and upload it: you get the transcript, subtitles to upload back, chapters and clips.
In YouTube Studio, open Content, pick the video, and choose Download from its menu. You get the MP4.
Drop the MP4, up to 4 GB. Muvero transcribes it with speakers and timestamps.
Upload the SRT to YouTube's subtitles, paste the chapters into the description, and cut reels for Shorts.
