mandelbrot

Generate a Mandelbrot set fractal, and progressively zoom towards the point specified with start_x and start_y.

This source accepts the following options:

'end_pts'

Set the terminal pts value. Default value is 400.

'end_scale'

Set the terminal scale value. Must be a floating point value. Default value is 0.3.

'inner'

Set the inner coloring mode, that is the algorithm used to draw the Mandelbrot fractal internal region.

It shall assume one of the following values:

'black'

Set black mode.

'convergence'

Show time until convergence.

'mincol'

Set color based on point closest to the origin of the iterations.

'period'

Set period mode.

Default value is mincol.

'bailout'

Set the bailout value. Default value is 10.0.

'maxiter'

Set the maximum of iterations performed by the rendering algorithm. Default value is 7189.

'outer'

Set outer coloring mode. It shall assume one of following values:

'iteration_count'

Set iteration count mode.

'normalized_iteration_count'

set normalized iteration count mode.

Default value is normalized_iteration_count.

'rate, r'

Set frame rate, expressed as number of frames per second. Default value is "25".

'size, s'

Set frame size. For the syntax of this option, check the (ffmpeg-utils)"Video size" section in the ffmpeg-utils manual. Default value is "640x480".

'start_scale'

Set the initial scale value. Default value is 3.0.

'start_x'

Set the initial x position. Must be a floating point value between -100 and 100. Default value is -0.743643887037158704752191506114774.

'start_y'

Set the initial y position. Must be a floating point value between -100 and 100. Default value is -0.131825904205311970493132056385139.
