Turn a six-hour stream into a clip worth posting

Sound familiar?

• ✗A six-hour VOD gets almost no replay views
• ✗Clipping highlights by hand takes longer than the stream did
• ✗Running a second full-rate recorder next to OBS costs performance you need for the stream

How Tau helps

• Runs beside your streaming software

  Tau captures frames at intervals rather than full-rate video, so it uses a fraction of the resources a second recorder would take from your encode.

• Post the whole session, not a highlight

  A timelapse of an entire stream reads as a recap — good for a channel trailer, a schedule post, or showing what a long build actually looked like.

• Export vertical for clips

  Export straight to a 9:16 MP4 for TikTok, Reels, or Shorts without moving the file into a separate editor first.

FAQ

Will running Tau hurt my stream performance?

Very little. Tau captures a frame at a set interval instead of encoding continuous video, so it leaves far more headroom for your streaming software than a second full-rate recorder would.

Can I record my camera as well as the screen?

Yes. Tau can record your screen and camera at the same time, so a recap can show both your gameplay and your reactions.

What length works best for a stream recap?

Somewhere between fifteen and sixty seconds. Use the frame interval calculator to work out the capture interval that turns your stream length into that.
