  2. Unlock the panel (bottom left lock icon, login)
  3. On the left side click on Camera
  4. On the right side, make sure there is a check next to the Kaltura Capture software. If the software is not in the list, Capture is not properly installed

  6. Re-lock the panel

Close the app and re-launch

Best practices and tips for a good recording experience

  • Shut down all software and browser tabs not needed for the recording. Leaving your Gmail running in the browser consumes a lot of memory, so make sure it is shut down. 
  • Check your microphone in the Capture application to be sure the right device is selected. 
  • Choose to make shorter recordings rather than one long one. Your audience will appreciate it and if you have to recover from a recording error, less work is lost. 
  • Recordings are stored on your computer until you delete them in the Capture application. Deleting files in Capture does not delete uploaded files from your My Media library
