When you render an effect, the Avid editing application creates two elements: a rendered effect clip (also known as a precompute clip) and an associated media file. When you create a title or an imported matte key clip, the application creates several elements: an effect clip, a precompute clip, and associated media files.

The Avid editing application overwrites or automatically deletes a media file from your drive only if you:

In this case, the Avid editing application automatically saves the last-rendered effect and deletes the earlier, unreferenced versions. This autodeletion applies only to effects rendered since the last save or project close.

This prevents you from deleting media that might be necessary to play other versions of the sequence. If you want to remove media files from your drive to save space, you have to manually delete the files.
