Note

Saving a sequence as a VPX file maintains the elements of the queue, but it resets all parameter settings. Saving the file as a Max file maintains the queue order along with the parameter settings. •

You can open saved sequences using the Open Sequence button on the toolbar. When a saved sequence is opened, all the current events are deleted. Clicking the New Sequence button also deletes any current events.

The Execute Sequence toolbar button opens the Execute Video Post interface, shown in Figure 49.9. The controls in this dialog box work exactly the way those in the Render Scene dialog box work.

Note

The time and resolution settings in the Execute Video Post dialog box are unique from those in the Render Scene dialog box. •

The Execute Video Post interface includes the controls for producing the queue output.

The Time Output section enables you to specify which frames to render, and the Output Size section lets you specify the size of the output. The Custom selection lets you enter Width and Height values, or you can use one of the presets in the drop-down list or one of the preset resolution buttons. This dialog box also includes controls for entering the Image Aspect and Pixel Aspect ratios.

The Output options let you select to keep the Progress dialog box open, to render to the Rendered Frame Window, and/or to use network rendering. When you're ready to render the queue, click the Render button.

Adding and Editing Events

The seven event types that you can add to the queue are Image Input, Scene, Image Filter, Image Layer, Loop, External, and Image Output. If no events are selected, then adding an event positions the event at the bottom of the list. If an event is selected, the added event becomes a subevent under the selected event.

Every event dialog box, such as the Add Image Input Event dialog box shown in Figure 49.10, includes a Label field where you can name the event. This name shows up in the queue window and is used to identify the event.

The Add Image Input Event dialog box lets you load an image to add to the queue.

Each event dialog box includes a Video Post Parameters section. This section contains VP Start Time and VP End Time values for defining precisely the length of the Video Post range. It also includes an Enabled option for enabling or disabling an event. Disabled events are grayed out in the queue.

To edit an event, you simply need to double-click its name in the Queue pane (or press Ctrl+E) to open an Edit Event dialog box.

Note

Remember that you need to enable the Keyboard Shortcut Override button on the main toolbar before you can use any keyboard shortcuts in the Video Post interface. •

Adding an image input event

The Add Image Input Event dialog box lets you add a simple image to the queue. For example, you can add a background image using this dialog box rather than the Environment dialog box. To open the Add Image Input Event dialog box, click the Add Image Input Event button (Ctrl+I) on the toolbar.

Tip

If you don't name the image event, then the filename appears in the Queue pane as the name for the event. •

The Files button in this dialog box opens the Select Image File for Video Post Input dialog box, where you can locate an image file to load from the hard disk or network. Supported image types include AVI, BMP, MPEG, Kodak Cineon, Combustion, FLC, GIF, IFL, JPEG, PIC, PNG, PSD, MOV, SGI Image, RLA, RPF, TGA, TIF, and YUV. The Devices button lets you access an external device such as a video recorder. The Options button becomes enabled when you load an image. The Cache option causes the image to be loaded into memory, which can speed up the Video Post process by not requiring the image to be loaded for every frame.

The Image Driver section of the Add Image Input Event dialog box lets you specify the settings for the image driver, such as the compression settings for an AVI file. Clicking the Setup button opens a dialog box of options available for the selected format, but note that the Setup button is not active for
