Record online course & teaching videos from your screen or whiteboard
Teaching videos need clean visuals and clear voice. Excalicast records your whiteboard, a tab, a window, or the desktop with synced microphone audio, and on Pro adds auto subtitles (Alibaba Qwen ASR), so a lesson becomes a captioned MP4 ready for your course platform.
Short answer
To record an online course, teach on the Excalicast whiteboard or record a tab/window with voice, then export a narrated MP4 — Pro adds auto subtitles. No screen-recording software or account is needed to start.
Workflow
- 1
Prepare the lesson
Lay out the lesson structure on the whiteboard or open the tab/window you will demonstrate.
- 2
Choose the aspect ratio
Pick 16:9 for course platforms or 9:16 for short recap clips — the same recording can render to both.
- 3
Teach and record
Explain while recording. Enable the camera bubble if you want a talking-head presence.
- 4
Add subtitles and export
On Pro, generate subtitles (Alibaba Qwen ASR), then export the MP4 in your platform’s ratio.
FAQ
Can I add captions to teaching videos?
Yes. On the Pro plan Excalicast generates subtitles with Alibaba Qwen ASR (Chinese & English), downloadable as SRT or burned into the MP4.
Can I record a slides or PPT window?
Yes. Choose the window source and record the slides with your voice, or switch to the whiteboard for handwritten derivations — both export through the same workflow.
