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 cound 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 "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.
