You can also do the same with multiple stills and retain full resolution, which may be easier to work into a regular photo workflow. Take a dozen shots at ISO 9000000 and pipe into enblend -> crystal clear result.

Good idea. I'll add support for still images.

I originally wrote this for a computer vision application (averaging frames attenuates low-light noise) but I'm curious what other use cases people come up with. :)

Very clever idea. Can't wait to try this!

Thanks. Let me know if you have any feature requests.

How about making it output video, with a rolling average over the previous N frames. Then you can experiment with having the brightness of a pixel impact how many frames are affected. For example, make brighter pixels have a longer impact to get light streaks, or have darker pixels last longer for a kind of hdr effect.

Cool, now do image stabilization so it works with handheld video.

And what's the point of that? Videos are generally low resolution, compared to photos. We're talking order of magnitude difference - 2 megapixels vs 36 megapixels.
