Not to rewatch the whole thing but rewatching is just passive review in slower motion and two hours of video is not something I have time to revisit in full. The recording is useful because you can jump to the exact timestamp where a specific concept was introduced rather than scrubbing through docs that assume you already understand the thing you're trying to learn.

The combination that works is recording the session, taking notes live in remnote and flagging anything I didn't fully follow in real time with a simple marker, then going back only to those specific timestamps afterward. The flagging step is what makes the recording useful at all. Without it you have a full recording and no way to find the 8 minutes that actually matter without watching everything.

Flashcards come from the notes, not from the recording. Anything I flagged, went back to, and then understood becomes a card. Anything I followed during the session doesn't need one. That filter cuts card creation time significantly because I'm not trying to make everything reviewable, just the parts that were genuinely slippery for me specifically.

The recording as a backup for your own confusion is a completely different tool than the recording as a substitute for attention during the live session. If you're recording to watch later instead of paying attention now it's not really helping.
