animation. This defaults to the earliest solution time in the

animation. This defaults to the latest solution time in the
dataset.
timestep_step (`int`, optional): The number of timesteps to increments
for each frame of the animation. (default: 1)
width (`int`, optional): The width of the video in pixels. (default:
800)
animation_speed (`int`, optional): The frame-rate of the video in

The rectangular area to be exported. This can be a specific `Frame

supersample (`int`, optional): Controls the amount of anti-aliasing

jagged edges on text, lines, and edges of the video output by the
process of supersampling. *Some graphics cards* can cause Tecplot
360 to crash when larger anti-aliasing values are used. If this
occurs on your machine, try updating your graphics driver or using
a lower anti-aliasing value. (default: **3**)
format_options (`str`, optional): A string of options passed directly
to the underlying application `FFmpeg <https://www.ffmpeg.org/>`_.
By default, this will be "-vcodec mjpeg -q:v 5".

``gray_scale_depth`` specifies the number of shades of gray by how
many bits of gray scale information is used per pixel. The larger
the number of bits per pixel, the larger the resulting file.
Options are: * **0**: On/Off One bit per pixel using an
on/off strategy. All background pixels are made white (on),
and all foreground pixels, black (off). This setting
creates small files and is good for images with lots of
background, such as line plots and contour lines. *
**1**: 1 Bit per Pixel One bit per pixel using gray scale
values of pixels to determine black or white. Those
pixels that are more than 50 percent gray are black; the
rest are white. This setting creates small files that might
be useful for a rough draft or a preview image. *
**4**: 4 Bits per Pixel Four bits per pixel resulting
in sixteen levels of gray scale. This setting generates
fairly small image files with a fair number of gray levels.
This setting works well for most preview image purposes. *
**8**: 8 Bits per Pixel Eight bits per pixel resulting in
256 levels of gray. This setting is useful for full image
representation, but the files generated by this setting can
be large.
