Video/Image Sequence

Choosing to export  as an image sequence lets you leverage the bulk of the effects possible inside of Visualize by rending them out as image frames.

Visualize exports an image sequence by default, and as such most functionality within in the tool is built for this type of export. Exporting for video works by rendering a given composition from the perspective chosen in the camera track (what you'll see in "Lock to Track" mode in Settings) into a series of PNG frames.

Frames render at 1920x1080 by default but can be changed on the right-hand side of the Settings in the Visualize app by changing the Frame Width & Frame Height Sliders. There are presets for 720P & 1080P built in below the sliders.

The image sequences will be rendered out with the black background as transparent using an Alpha channel for compositing. However, if "Draw DoF" is checked it will remain black or if you've changed the background color it will not render with an alpha channel.

Designing Shots for Export

Camera Moves

What's a video without camera moves? To create a camera move, navigate to the "Camera" tab of the Timeline, and then scrub to a place in the timeline you'd like to start your move. Adjust the camera in the Scene Viewport to reflect the angle/orientation you'd like for the camera to have at that point. 

Once you find a position you like, either press "Set camera point" on the GUI or press SHIFT+T to create a keyframe at that time and location. You'll see the keyframe you created represented by a blue marker appearing on the Camera timeline. You can then scrub to a different place on the camera track, move the camera to a new location, and press SHIFT+T again to create another keyframe. In doing this, you're setting "In" and "Out" points for your camera move, declaring where the camera should start, and where the camera should end.

To see the actual camera move you just designed, select "Lock to Track" (or press SHIFT+L) on the Settings panel, then press Space to play. You'll see the camera traveling along a path your just described with your two key frames.

Other Keyframe Actions

  • You can click and drag the camera points to change their location in time.
  • You can delete them with the Delete or backspace key.
  • Right-clicking on a keyframe allows you to select different tweening methods between keyframes.
  • By clicking on the triangles to the left or right of the marker and pressing the up or down arrows you can have the camera movement ease in or out represented by a curved arc, or cut (blocky steps.)

Depth of Field

The Depth of Field effect can be convincing for simulating a camera language. To get started, select "Draw DOF" from the Settings menu. Next, navigate to the "Depth of Field" tab in the Timeline. You can adjust the Depth of field setting by setting keyframes and values in the tracks in this tab.

Depth Distance in the Depth of Field tab allows you to change the focus plane is in relation to the camera - think of this like turning the focus ring on your camera.

Depth Range changes how large your focal plane actually is. Think of this like adjusting the aperture.

Depth Blur controls how much blur should be applied to out of focus objects. 

Depth of field keyframes matched to camera moves can simulate racking or tracking focus. The white rectangle on the top right acts as a focus-assist by marking the area in focus in white and previewing the focus range.

A Few Tips

  • The rendering styles are screen-blended onto one another. So you can get a lot of mileage out of combining points, wireframes and meshes together & varying opacities.
  • If you don't feel like you can get the aesthetic you want, you can duplicate comps and render out multiple passes allowing you to blend in an external compositing tool like After Effects.
