Hi Gunnar,

thanks for the great filter!

I have mounted a keychain-camera to a model airplane and use your filter to improve the resulting videos. Although (as you have mentioned before) the filter is not designed for this purpose the results are quite impressive. One issue I am facing though is the relatively high amount of dropped frames these kinds of cameras produce, which appear as duplicate frames in the video. Deshaker perceives these duplicate frames as proper individual frames and this leads to bad results. I was thinking that it might be a good thing if you only compared the first frame of a series of duplicate frames to the next real frame following the duplicate frames and then spread the resulting adjustments evenly over the series of duplicate frames. I am guessing that identifying duplicate frames should be feasible, since they show zero motion compared to preceding images.

Just an idea.

Thanks for all the time and effort you put into this!
