Rendering menu Video Post Video Post window Make sure no events are selected in the queue. Video Post toolbar (Add Image Input Event) Select a file for input. Options

The Image Input Options dialog contains controls for setting the image's size and placement relative to the frames of video output. For animated input, you also use it to synchronize the Image Input event with the frame sequence of video output. The same dialog appears when you click Options from the Mask area of the Filter Event and Layer Event dialogs.


To align the input image, do one of the following in the Image Input Options dialog:

  1. Choose Presets and then click one of the preset alignment buttons.
  2. Choose Coordinates and then enter the X,Y coordinates for the image's location.

    The upper-left corner is (0,0) for both the input image and the output frame. Increasing X moves the image to the right, and increasing Y moves the image down. Negative values move the image in the opposite direction. X and Y values specify pixels.

To set the input image size, do one of the following in the Image Input Options dialog:

  1. Choose Do Not Resize to maintain the image's original resolution.
  2. Choose Resize to Fit to change the image size to match the output frame.

    This can change the image resolution, causing it to be rescaled for every frame.

  3. Choose Custom Size and then enter the width and height of the image in the output frame.

To control playback of an animated image:

  1. In the Frames group, set the From, To and Step values.
  2. Select Loop at the End if you want the animation to repeat. Clear Loop at the End if you want the animation to stop after playback.

    This option applies only when the input animation is shorter than the final video.
