For this use case add --use-given-order to the call of align_image_stack. 
By default images will be sorted by exposure values.

Title:
  Control points are not generated reliably

Status in Hugin:
  Invalid

Bug description:
  I am trying to generate control points for a stack of images (which I
  intend to process into a time-lapse sequence). All images were taken
  from the same position (save for some camera shake) at intervals
  between 1 and 4 seconds, thus there are plenty of control point
  candidates.

  I import them (using the Advanced interface) and select a batch of 120
  consecutive images (as I get an error about to many arguments being
  supplied when the number of images approaches 127), then I generate
  control points.

  When I examine the control points, I notice that sporadically there
  are pairs of consecutive images that do not have any control points
  between them. I have to go back to the first tab, select those two
  images separately, then regenerate the control points again (with the
  same settings as before). After that, the control points are there.

  This has happened on every sequence I have processed so far. In 120
  images, I usually have around a dozen image pairs without control
  points. Since explicitly regenerating control points works, the images
  are similar enough for Hugin to recognize similar features in them. It
  looks like the script which generates the control points occasionally
  skips some of the images it iterates over.

  I use the "Align image stack" script to create control points. The
  Hugin version is 2015.0.0.cdefc6e53a58, as supplied with Ubuntu 16.04
  LTS.

  of-images-for-a-timelapse-with-foss-tools/83156#83156.
