Could you add a flag which, when set to true, would save the render as a sequence of images which could later be joined in video editing software (like blender

) to show the development of the picture. For example:
<sequence = true>
<seqrate = 120>
saves images:
thisrender0001.jpg
thisrender0002.jpg
thisrender0003.jpg
every two minutes.
Would be great to watch some of these scenes developing in front of our very eyes
