The Add Scene Event button adds the scene in the selected camera viewport to the queue. A Scene event is a view of the current 3ds Max Design scene. You can choose which view to display and how to synchronize the scene with the final video. Like Image Input events, Scene events place an image in the queue, but a Scene event is the current 3ds Max Design scene and it must be rendered when you execute the Video Post queue. The scene is rendered exactly as it would be by the scanline renderer, with the additional options listed below. The resulting scene image has an alpha channel.

You can use multiple Scene events to show two views of the same scene simultaneously or to cut from one view to another. If you have more than one Scene event in the queue, and they occupy the same time range, composite them with an Image Layer event such as Cross Fade or Simple Wipe. Otherwise, the second Scene Event overwrites the first even though your system has spent the time processing both events.


To add a Scene event:

  1. Make sure no events are selected in the queue.
  2. Click (Add Scene).

    An Add Scene Event dialog appears.

  3. Choose a view to use from the View list.
  4. Click Render Setup to change rendering settings from the way you have set them in the Render Setup dialog.
    NoteUnlike settings in the Execute Video Post dialog, changes you make to the Scene event rendering options change the Render Setup dialog settings, and vice-versa.
  5. Set the Scene Range options and click OK.

    The Scene event appears at the end of the queue.

To match the scene's frames with Video Post frames:

To offset the scene in time:

To offset the scene and change scene playback rate:

To render the full scene backwards:

  1. Turn off Lock To Video Post Range.
  2. Turn off Lock Range Bar To Scene Range.
  3. Set Scene Start to the last frame in the scene.
  4. Set Scene End to the first frame in the scene.

    The length of the range bar also determines the playback speed of the reversed scene.

To add scene motion blur:

  1. Select Scene Motion Blur in the Scene Event dialog.
  2. Set the scene motion blur parameters.

    The Scene event generates motion blur by simulating a camera with an open shutter. It interpolates and then renders movement within a frame, to generate a series of images of the moving object, instead of the default single image.


The Add Scene Event and Edit Scene Event dialogs have the same controls.

View group


Lets you edit the event name. A unique name can make the scene event easier to distinguish in a long list of events.


Select the viewport you want to render.

Scene Options group

Enables various rendering effects.

Render Setup

Displays a subset of the Render Setup dialog parameters. Changes you make here affect the Render Setup dialog as well.

Scene Motion Blur

Turns on the scene motion-blur effect for the whole scene. This is different from object motion blur, which creates motion blur for individual objects in the scene.

When you render with Scene Motion Blur activated, the Render Progress dialog tells you which subsample is being rendered. The information appears in parentheses to the right of the "Rendering Image" text.


Sets the virtual shutter speed for motion blur. When set to 1.0, the virtual shutter is open for the entire duration between one frame and the next. When set to a smaller number, such as 0.25, the number of subdivisions specified in the Duration Subdivision field will be rendered within the specified portion of the frame (in this example, in the first fourth of the duration between one frame and the next).

Duration Subdivisions

Determines how many sub-frame slices are rendered within the Duration. The default is 2 slices, but you'll want at least 5 or 6 to get a decent effect.

Dither %

Sets the amount of dithering between blurred pixels of overlapping frame slices. If Dither % is set to 0, no dithering occurs.

Scene Range group

Scene Start/End

Sets the range of scene frames to be rendered.

Lock Range Bar to Scene Range

Becomes available when you deselect Lock To Video Post Range. When it's available, the End spinner is disabled and locked to the Video Post range. When you change the Start spinner it automatically updates the End spinner based on the Video Post range set for this event.

If you turn off Lock Range Bar To Scene Range, you can change either Start or End spinners to whatever you want. This allows you to keep your scene range locked to its native length, and still provides flexibility for mapping an arbitrary scene range to an arbitrary Video Post range.

Lock to Video Post Range

Renders the same range of scene frames as Video Post frames. You can set the Video Post range in the Execute Video Post dialog.

Video Post Parameters group

VP Start Time/End Time

Sets the starting and ending frames for the selected event within the overall Video Post queue. Video Post renders the event over the number of frames specified here.


Toggles the event. When off, the event is disabled and Video Post ignores it when rendering the queue. You must disable each event individually. For example, disabling a composite layer event does not disable the composited image events. The range bars of disabled events are unavailable in the event track area.
