Adding Clips to the Schematic

You can add clips to the Batch schematic in the following ways:

- Use the input nodes to load clips from the Desktop reels or a clip library, or import a clip from a different format.
- Double-click a node's input tab to load clips from the Desktop reels.

When you load or import clips from remote clip libraries, Batch does not duplicate storage on the local framestore. The import process occurs one frame at a time as you jog the timebar. In this way, the framestore is not cluttered with duplicate information.

To add clips to the schematic:

1. In the Batch menu, select BatchSchm from the View box.
2. Drag one of the following nodes to the schematic.

   Select: | To:
   --- | ---
   Desk node | Add clips from the Desktop reels. You can select up to six clips. Click Exit Clip Select to return to Batch. See Desk Node.
   Library node | Load clips from a local or remote clip library. Select the clips and click a Load option. See Library Node. NoteWhen using the Library node for a clip originating from an imported library, the proxy resolution of the remote clip may not match the proxy resolution of the current project. If this occurs, load the remote clip on the Desktop first, and then bring it into Batch.
   Import node | Import images and clips using the Import Image module. See Import Node.
   Gateway Import | Import images, clips, multi-channeled or not, and Gateway .clips, and while keeping import options available. See Gateway Import node.

3. Select the clips you want to add to the Batch schematic.
4. Click Load, or EXIT Clip Select when using the Desk node.

   You return to Batch and your selected clips are displayed as proxies in the schematic.

NoteWhen adding a 10-bit clip to the Batch schematic, an automatic linear gamma conversion to an 8- or a 12-bit image occurs. When adding clips with these file formats, the LUT Editor option is automatically enabled. Unless you are using a Gateway Import clip, which has no LUT Editor; you need to add a LUT Editor node manually, if desired

To replace a clip in the schematic:

1. In the Batch schematic, triple-click a clip.
2. Select the replacement clip.
3. Click Load, or EXIT Clip Select when using the Desk node.

   In the Batch schematic, the original clip is substituted for the new selection.

Importing Multiple Resolutions

You can import clips of resolutions other than the default resolution defined for the project. The resolution and aspect ratio display directly on the clip in the schematic. Proxies are also displayed in their correct aspect ratio.

Nodes with multiple inputs, such as the Keyer and Colour Warper, must use clips of the same resolution. For example, the Front and Back inputs must be of identical resolution. If you want to add a clip with a different resolution as an input, you must either parent a Resize node between the clip and the input of the node, or resize the clip itself. For Action nodes, each Action layer must also use a front and matte of the same resolution. However, separate layers can have different resolutions.

Using Proxies in Batch

Use proxies to work with low-resolution versions of your high-resolution material. Using an image's proxy to perform colour corrections, blurs, or other edits significantly increases the interaction speed. Proxies of your clips are generated according to your project settings and conditions.

To use proxies in Batch:

1. In Batch, click Setup to display the Batch Setup menu.
2. In the Rendering section, enable Use Proxies.

   All clips replace their respective proxies as defined at project creation. The image window is outlined in amber.

   TipPress Ctrl+P to toggle the Use Proxies button at any time, from any location in Batch.
3. If you click Process while in Proxy mode, you are asked to confirm whether you wish to render the proxies rather than the original clips.
