How to increase the speed of playblast options

Time Range

Can be used to set whether the play preview displays the entire time range in the Time Slider, or whether to set the play preview own start and end frames.

Time Slider

When enabled, the playback preview will be based on the current time range in the Time Slider.

Start/End

When enabled, the playback preview will be based on settings using the Start Time and End Time fields start time and end time.

Use Sequence Time

When enabled, the playback preview will be based on the Sequence Time in the Camera Sequence Editor. (See also Camera Sequencer Timeline and Playback Controls.)

View

When enabled, Playblast displays images using the default viewer . When disabled, playblasted images are saved to a file based on the Movie file setting in the Playblast Options window.

Show Ornaments

Will show the camera name and the axis at the origin and lower left of the view.

Render offscreen

Can be used to play previews using an off-screen render buffer (instead of a screen grab). For example, you can use the Script Editor to play a preview without opening the Maya scene view.

Multi-Camera Output

Use this option with a stereo camera to capture the output of the left and right cameras. If the scene view is in stereoscopic mode and the Save to file attribute is selected, selecting this option will send a set of images/movies to disk.
