Creating an animated GIF

Question

I used Animate to create an animation. However, is there a way to set $a$ to a value (say in 1/4 steps, starting at zero), run through the range of $b$ values (say in 1/4 steps), then change $a$ to the next value and run through all the $b$ values and to display both values as the animation is running?

Animate[
  StreamPlot[{-x + a*y + x^2*y , b - x^2 - a*y }, {x, -5, 5}, {y, -5, 5}, 
    ImageSize -> Large], 
  {a, -5, 5}, 
  {b, -5, 5}]

I want to create a GIF image of the above. When I look at Create Animation, is it saying that you have to pass a list of graphics and use Export to export those as a GIF? Is there no way to use Animate directly to do this?

@MichaelE2: What a horrible result using MantoGIF. The result has blackouts, is unsteady and is also 150 MB. — Moo, Dec 20 '16 at 00:16
I haven't used ManToGIF very much; I have my own way. In this case, I think changing Animate to Table gets you nearly there. Add your own increment to the iterators, and Flatten the result to give to Export. — Michael E2, Dec 20 '16 at 01:15

The simplest way creating the GIF-animation is Export of image list without any Animate. The "DisplayDurations"->xx option can set the time (xx seconds) of demonstration of each frame.
