Show a whole lesson or build in under a minute

How Tau helps

• Compress a long session into a preview

  Record the whole lesson and export a short timelapse that shows the shape of the work — useful as a preview before class or a recap after it.

• Show elapsed time

  A timer overlay makes it clear how long each stage genuinely took, which is the part students most often misjudge.

• Small files, easy to share

  A timelapse is a fraction of the size of the equivalent full recording, so it uploads to a VLE or shared drive without trouble.

FAQ

Can I record a physical demonstration rather than my screen?

Yes. Tau records from your camera as well as your screen, so a lab bench or a whiteboard works the same way a screen session does.

Is the export small enough to upload to our VLE?

Usually, yes. Because a timelapse holds far fewer frames than the equivalent full recording, exports are typically a few megabytes rather than gigabytes.

Do students need Tau to watch it?

No. Tau exports standard MP4, GIF, and WEBM files that play anywhere.
