I presume their satellites aren't equipped to take more than one image per second. (For most of their applications, it's not necessary, and adding that ability to a microsat is would definitely increase the weight/cost/power.) You can watch it on 25% speed on YouTube. It's pretty jittery, so it would be nice if someone made an interpolated version.

I tried using butterflow and it seems ok at first, but I guess the algo is not made for this weird shot. https://www.youtube.com/watch?v=8a6QoKQNGWA&feature=youtu.be https://www.youtube.com/watch?v=8a6QoKQNGWA&feature=youtu.be This one might be better. FPS is set to 60 and speed is the same: https://youtu.be/b7Ua4mXO23E https://youtu.be/b7Ua4mXO23E

Their satellites have a one dimensional sensor that scans continuously.

  They are using 2D TDI CCDs, just like everyone else. This timelapse was likely shot with frame by frame exposures though. I'm not sure how it's possible with TDI.

    Still inherently 1D. TDI sensors are not like area arrays.
