Cache Pane

The Cache pane contains settings to control the cache for projects. There are four categories of controls: Memory & Cache, Autosave, LiveFonts, and Optical Flow Retiming.

Memory & Cache

This setting in the Cache pane of the Preferences window lets you specify how much memory is allocated to the project cache.

  • Project Cache: Enter a number in the value field to specify the percentage of your total system memory that you want to use for the project cache. The larger the number, the more memory available to Motion to cache frames, resulting in a higher likelihood of consistently smooth playback.

Autosave

These settings in the Cache pane of the Preferences window control how frequently projects are automatically saved, as well as the location of the saved files. Saved projects are time-and-date stamped.

  • Use Autosave Vault: When this checkbox is selected, Motion stores auto-saved projects to the location specified by the Autosave Vault Folder path. By default, the Autosave Vault folder is located in a folder called Motion Documents in the Documents folder of your home directory.
  • Save a copy every: Specifies how often, in minutes, a project is saved.
  • Keep at most: Specifies how many versions of the autosaved project to store in the vault.
  • Maximum of: Specifies the maximum number of different auto-saved projects to store in the vault.
  • Autosave Vault Folder: The Choose button allows you to set where the Autosave files are kept. The Reset button sets the Autosave location back to its default.

Customizing Autosave

There are a number of ways to customize Autosave for your needs.

To store auto-saved projects in a specific location
  1. Choose Motion > Preferences (or press Command-Comma).

  2. Click Cache.

  3. In the Autosave group, turn on Use Autosave Vault.

    By default, the Autosave Vault folder is located in a folder called Motion Documents in the Documents folder of your home directory.

To set a new location for the Autosave vault
  • Click Choose, set a new location in the dialog, then click Choose.

To revert to an auto-saved project
  1. Choose File > Restore from Autosave.

    Figure. Restore Project dialog.

    The Restore Project dialog appears.

  2. Choose a saved project from the pop-up menu.

    Note: A project must be saved before the Revert commands are available in the File menu.

LiveFonts

These settings in the Cache pane of the Preferences window determine how LiveFonts are cached (stored) by Motion. For more information about LiveFonts, see Using LiveFonts.

  • Cache intermediate LiveFont sizes: This checkbox turns caching of LiveFont data on or off. This option is on by default, as it improves performance if you frequently use LiveFonts.
  • Cache Path: Click Choose to define a custom location to cache your LiveFont data. Because this cache can grow quite large, it is advised that you set this to a drive other than your primary system drive.
  • Delete LiveFont Cache: Over time, your LiveFont cache can grow to take up many gigabytes of disk space. To recover this space, you can delete the cache by clicking this button.

Optical Flow Retiming

When you retime footage, Motion needs to store the retiming files. This setting in the Cache pane of the Preferences window specifies where the retiming files are stored. You can choose to store the files in the same location as the source footage or specify your own location.

  • In folder with source media: Click this button to save the retiming files in the same location as the source footage.
  • In this folder: Click the Choose button to specify where the optical flow retiming files are stored. By default, the Optical Flow folder is located in the /Users/username/Documents/Motion Documents/Retiming Cache Files folder.
