The purpose is to blend these alternating frames (thereby halving the effective frame-rate) in a similar way as when we blend multiple images into 1 HDR image.
Is it possible for "Dynamic Photo HDR" to be updated so it can load such video-sequences and automatically do the blending?
Magic Lantern can shoot video in this flickering way. Read more here: http://magiclantern.wikia.com/wiki/Release_2011Dec22
Here's a short test-video that shows how the shot video looks like before being blended: http://vimeo.com/34028226
And here's the same test-video after having been blended into an HDRvideo by other software: http://vimeo.com/33987353
And here's some more talk about all of this: http://vimeo.com/groups/magiclantern/forumthread:250295
It would be so cool if DPHDR's pseudo-videoHDR could be updated to include an option for these type of videos, since that would make it useful for creating REAL HDR-videos

Thanks
