Recording whiteboard lectures for online teaching: a complete guide
To record whiteboard lectures for online teaching, capture the operation stream plus voice in the browser, add subtitles, and export an MP4 in your platform’s aspect ratio — no screen-recording software and no sign-up to get started.
Why operation-stream capture matters for teaching
Teachers often switch tabs to pull up references mid-lesson. With screen recording that mess ends up in the video; with operation-stream capture the lecture stays clean and the audio keeps recording, so the lesson flows uninterrupted.
Subtitles and accessibility
On the Pro plan, generate subtitles with Alibaba Qwen ASR (Chinese & English) and download SRT or burn them in. Captions improve accessibility and watch-time, and help non-native learners follow along.
