capture movies

When I was capturing an online video, there was a window popping up to cover my video, what should I do to avoid it?

You can select the option "Set the target capture window to topmost when capturing" in the "Setup" window. You can select it to make the target window above any other window during the capturing process.

How to capture streaming video/audio or anything on the PC?

When you are not running Stream-Cloner:
Step 1 Open the webpage where the online movie or streaming video you want to capture is played back.
Step 2 Right click on the webpage (not on the video) and then click "Capture video with Stream-Cloner".
