Do video formats support structured meta data to be embedded in them?

If I make a video of me cooking, can I embed the recipe in the video, etc. Not just visually, but i.e. at 10s, I digitally insert the data "Add 1 cup red peppers". It isn't necessary a caption of something said or shown, just extra data.

Could a video creator leave substantially more metadata in their videos? I always assumed the pop-up metadata was externally stored and timestamp synced. Is there a way to embed it?

That sounds a bit like subtitles, or Timed Text. There are simple formats (just a text and the moment it should appear) but some formats support changing the position, color, font… most of the times this would be embedded in an extra sidecar file like an .srt or a .sub

It would be better all-around to just have that data in a separate file with timestamps.
