Study from a recorded lecture without rewatching the whole hour

Rewatching an hour because you missed one definition is a poor default. The second watch is still linear. You need an index, then a way to test whether the idea is yours.

Make the file searchable

Upload the lecture on the home page. Wait for the transcript. Search the word you did not catch. Jump to that minute. Use chapters to skip “can you hear me” and the lost-microphone stretch. Chat only with questions the transcript can answer — if the reply has no time, treat it as untrusted.

Write three lines in your own words only after you can point to a time for each. If you cannot point, you do not have the idea yet.

Test from this file, not from a topic

Quiz from this recording drafts questions that should be answerable only from that lecture. A miss jumps back to the source. That is different from a generic quiz that asks whatever the topic name suggests.

If you are a teacher, edit the draft before anyone else sees it. If you are studying alone, still throw out items that hinge on a mumbled formula.

When a quiz is the wrong tool

A viva from a script is Script vs delivery. A seminar that was really a discussion is closer to transcribing a meeting than to a lecture quiz. Slides with almost no speech will give you a thin transcript no matter what you do next. This is not a learning platform. It is a way to stop scrubbing the same hour.
