IF you want to record video (Ex. embeded video in PPT) directly, you must close hardware acceleration first.

1. Run [PowerCam/Configure/General] 
2. Check "Close hardware acceleration to record movie" 
3. Save 


  Recording video increases the size of file, run [PowerCam/Compression] to enhance 
      performance and reduce size.
  Instead of recording video, insert video is suggested (PowerCam/Edit) to reduce file size.
