: Clicking this button will render the input clip to the cache location specified in the cache menu.
Once the clip is cached, the button icon will change to show that the image data has been cached successfully: . Clicking the button again will clear the clip from the disk cache and free the disk space used.
The text browser will display information such as the filename of the cached data, the pixel format, number of frames, and the total disk space used by the file.
