The craters in the background sure look weird! This isn't a snapshot, of course; time as well as distance are covered along the long axis of the image, and the spacecraft was clearly doing something odd as it was setting up to track Phobos. But I don't understand what was happening to make the craters appear smeared in a stepwise fashion.

Anyway, cool colorization, Olivier.

I wonder if it's a bit like the way Mars stops, goes backwards, then carries on, night to night in the night sky.

Retrograde craters - I think you've got it, Doug.

That's a really stunning image! Which orbit is the colourised shot from? I can look up our attitude profile and see what might be causing the crater distortion (although I think you've already guessed it!).

Remarkable footage to say the least although I expected Phobos to pass even faster throught the image:

Images every 0.1s - slowed significantly in that animation - not surprising it comes across as 'slow'.

That statement needs a qualifier:

and

(sorry Stu it seems I've been picking on your posts a lot lately, nothing personal.)

If someone fancies putting two copies of the animation together with a one frame time difference that might work as a crosseye 3D animation.

Here is the ESA page on the images: http://www.esa.int/SPECIALS/Mars_Express/SEMDOE7JT2G_0.html

"For the very first time, the martian moons Phobos and Deimos have been caught on camera together. ESA's Mars Express orbiter took these pioneering images last month. Apart from their ‘wow’ factor, these unique images will help the HRSC team validate and refine existing orbit models of the two moons."

More information about how they got the images are on the page. Very cool sequence.

The image caption says "for the first time, possible to acquire images of Phobos and Deimos together in high resolution.." It seems like whoever wrote the press release failed to understand the significance of the last three words.
