2) Quicktime Pro + Soundflower (MAC only)
Quicktime Pro is available for approx. $35 from quicktime.com. Among many of its features it allows for you to make audio, video and screen recordings. However, if you want record the audio of a movie playing on the computer instead of recording your voice for example, you will need to also download Soundflower.
- Once you have installed Soundflower, you will need to go into SYSTEM PREFERENCES and change your audio input to Soundflower. This will redirect your system audio to play and be recorded. Without this, the audio you hear on the computer will not be recordable, only the video.
