Thinkific learning platform offers some fantastic third-party software integration to allow the screencasting of videos. Suppose you're new to screencasting and do not want to invest in any software for the purpose. In that case, QuickTime Player is free software available to both Windows and Mac users. For intermediate users, Screencast-O-Matic and CamStudio are popular inexpensive screen recorders. But suppose you're already familiar with screencasting software and regularly use them. In that case, Camtasia Studio is your choice for both Mac and PC, while ScreenFlow can be used only with Mac.
