III Planning for Additional Media Files In addition to space for captured files and project files, you need extra space for render files, graphics, movie files created in other applications (such as animations), additional audio files, and so on. A loose rule of thumb to determine how much space you need is to multiply the amount of space needed for your finished program by five. Ultimately, the amount of extra space you reserve depends on how much additional media you create during editing. For example, if you use hardly any effects, additional render files may not be a factor. If you are using only a few graphics files and little additional audio, these may not be a concern, either. Keep in mind that although real-time effects don't require additional drive space for rendering, you still need to render the effects at high quality for final output, so at that point you need enough drive space for render files. Calculating Hard Disk Space Requirements You can use the table below to estimate how much disk space you need for your project.
