Rendering menu Video Post Video Post toolbar (Execute Sequence)

You execute the Video Post queue as the final step in creating a post-produced video. Execution is different from rendering because rendering is done for scenes only and you can use Video Post to composite images and animations without including the current 3ds Max scene.

Although the Execute Video Post controls are similar to those of the Render Setup dialog, the setting are independent, and do not affect each other.

During execution, you can move or close the rendered frame window, but you cannot use the rest of 3ds Max until the execution is completed or cancelled.

The rendering time for the last rendered frame in the Video Post sequence is displayed in the prompt line of the main 3ds Max window.


To execute the queue:

  1. Click (Execute Sequence).

    An Execute Video Post dialog appears.

  2. Set the time range and output size, and then click Render to create the video.
  3. When execution is done, click Close to dismiss the Video Post progress dialog if it is still open.


Time Output group

Select the frames to execute:


Current frame only.

You can execute a single frame only if it falls within the current range.


All the frames between and including the two numbers.

Every Nth frame

Regular sample of frames. For example, enter 8 to execute every 8th frame.

Output Size group


Choose Custom or a standard film or video format from the list. For Custom, you can set the aperture width of the camera, the rendering output resolution, and the image aspect ratio or pixel aspect ratio. When you choose a standard format, the aperture width and aspect ratios are locked, but you can change the resolution.


Specify the width and height of the image, in pixels. For Custom, you can set these two spinners independently. For other formats, the two spinners are locked to the specified aspect ratio, so changing one changes the other.

Resolution Buttons

Specifies a preset resolution. Right-click a button to display a subdialog that lets you change the resolution specified by that button.

Image Aspect

Sets the aspect ratio of the image. As you alter the Image Aspect, you also alter the Height value to maintain the correct aspect ratio. For standard formats, the image aspect ratio is locked, and this spinner is replaced by a text display.

If you lock the Image Aspect (by clicking the Lock button), Width and Height are locked to each other, so that changing one changes the other to maintain the image aspect ratio, and changing the Pixel Aspect value changes the Height value to maintain the image aspect ratio.

Pixel Aspect

Sets the aspect ratio of the pixels of the image. For standard formats, the pixel aspect ratio is determined by the format and this spinner is replaced by a text display.

If you lock the pixel aspect ratio (by clicking the Lock button), the Pixel Aspect spinner is replaced by a text display. The Lock button is available only for the Custom format.

Output group

Keep Progress Dialog

Forces the Video Post Progress dialog to remain displayed when the Video Post sequence has finished executing. By default, it closes automatically. If this option is selected, you must click the Close button to close the dialog.

Rendered Frame Window

Displays the Video Post execution in a window on the screen.

Net Render

Enables network rendering. If Net Render is turned on, when you render you'll see the Network Job Assignment dialog.
