Reference Render Flipbook

Render a flipbook of the viewport.

See also: How to render wireframes

Overview

This dialog will record the viewport for the range specified and generate a flipbook rendering.

During the recording process, it is important that:

  • No other windows cover the viewport being recorded.

  • The window containing the viewport is not moved or resized.

  • In some cases, a screen saver may cause corruption of the recording process. For long recordings, it might be a good idea to turn off the screensaver.

Output

Frame start/end/inc

The start and end frames of the flipbook, and the number of animation frames to step through for each flipbook frame (1 = use every animation frame, 2 = use every other frame, 3 = use every third frame, and so on).

Use $RFSTART and $RFEND in the start and end frame boxes to automatically pick up the frame range set in the timeline.

Output

This specifies where to output the rendered images. By default, it renders to mplay (ip).

Visible objects

Only objects whose names match this pattern will be visible in the flipbook. Use this to focus the flipbook on the animation of just one or a few characters/objects.

Append frames to current flipbook

Adds the frames on to the end of the last flipbook you created, instead of starting a new flipbook. This lets you put together a flipbook of different parts of a larger animation.

Scoped channel key frames only

Only render at frames where there exists currently scoped keys.

Enable block editing

Generate a flipbook with keyframe information so that animation blocking might be performed. This only applies when rendering to mplay (ip).

Initialize Simulation OPs

If enabled, all simulation operators in the scene will be reset prior to rendering.

Flipbook

Audio filename

A sound file to play during the flipbook.

Audio offset

This specifies time (in seconds) of the audio that corresponds to the given frame number.

Background images

This specifies an additional background image when loading mplay (ip).

Gamma

This specifies gamma correction value for mplay (ip).

LUT

This specifies the look up table file for mplay (ip).

Effects

Antialias

Does full-scene antialiasing, with smooths edges.

Motion Blur

If enabled, a 2D motion blur will be performed when rendering.

Frames

The number of subframes to use when computing the motion blur. More frames produce better results, but take longer. The menu determines when the subframes are sampled.

For any frame F, Forward uses the interval F to F+1, Previous uses F-1 to F, and Centered uses F-1/2 to F+1/2.

Shutter

The shutter speed of the camera, normally taken from the source camera (From Camera). If Specify is selected, you can enter the shutter value in the next field. The shutter parameter controls how much of the frame the iris is open for, so longer shutters produce more blur. For example, if the value is 0 there is no blur and if the value is 1 there is full frame blur.

Depth of Field

If this option is turned on, the flipbook simulates depth of field. If From Camera is selected, the Focus Length, Aperture, and F-stop are all taken from the camera the flipbook is rendered from. If Specify is selected you will be able to specify the Focus Length, Aperture, and F-stop.

Quality

The number of renders done per frame to simulate depth of field. Higher numbers produce better quality flipbooks, at the expense of speed.

Focus Length

The distance from the camera at which objects are in focus.

Aperture

The amount that the iris is opened, producing more blur for higher numbers.

F stop

How quickly the focus drops off from the focus distance. Large F-stops produce a long area of focus (less blur), whereas small F-stops produce a very small area of focus (only the objects at the Focus Length will be in focus).

Size

Zoom

Reduces the size of the frames as they are added to the flipbook. This reduces the amount of memory the flipbook uses.

Resolution

The width and height of the flipbook frames. The default is the size of the current viewport.

Zoomed resolution

Shows the actual size of the flipbook frame after applying the Zoom option.

Crop Out View Mask Overlay

When the viewport aspect ratio does not match the camera aspect ratio, the area outside the camera’s view is grayed out. If this option is turned on, only the camera’s view is rendered. If not, the grayed out area is rendered in the flipbook as well.
