Audio and Video set-up preferences:

Scratch Disk:

• Most Digital Video editing systems require that you define a “Scratch Disk” in order to capture audio and video.
• The scratch disk is where the computer will write audio and video information temporarily while it is capturing.
• If there is only one Hard Drive on your computer then that will be the scratch disk, however if you have more then one Hard Drive it is best to assign one of the drives to your system software and the other to data (video, audio, image files). The data Hard Drive then should become the scratch disk
