Unfortunately I am also a know-nothing droid who didn't even realize we had an attendance policy or that some classes recorded lectures until halfway through last semester when we got an angry email about the first and a nice email reminder about the second lol.
Basically: lecture attendance isn't required unless there is a good reason/the professor requests it for specific reasons (think guest lecturers, unique class presentations, etc.), but attendance is required for labs and anything clinics-related unless you get it excused basically. Some classes will take attendance in the form of super easy quizzes about the lecture (think "Please give feedback to the guest lecturer" type questions, not real content quizzes), but that's usually because either the whole class consists of guest lecturers and has no exams so attendance is worth a grade (there's one in first semester like this) or it's a section of the class where they bring in some of the residents to practice their presentation skills (our pathology class in second semester does the week before finals to give us a break lol).
As for recorded lectures, that depends on the professor right now and most of them don't do it (at least in first year, not sure in second year). I think the exception is if you have a student like
@cdoconn in your class who needs lectures recorded. I'm not the greatest person to ask because I almost never watch through lectures again because of who I am as a person
