user16375: I have recorded a short movie using GoPro camera 1080p / Wide / 60fps. The video is really blurry, despite the fact that it was a quite good weather outside (middle of the day, partially cloudly). Is it possible to make the video sharper by lowering the framerate? All I need is 25% of speed, so 15fps. I'm just wondering if some video editing software can use the information from skipped frames to improve the video quality.
Here is the sample frame: http://imgur.com/NZkogOT


user6330: If your individual frames are blurry, cutting down the frame rate won't help. I assume that you mean you'll be converting the 60 fps footage to 15 fps in real time (cutting out 3/4 of the frames rather than keeping all the frames but slowing it down to appear 15 fps).
Think of it this way: changing the frame rate doesn't change the actual frames. If you slowly scroll through your footage frame-by-frame and it's blurry, then it will be blurry at any speed or frame rate.

user22644: Theoretically it IS possible, and there are working, practical, proof-of-concept research on the subject.
A couple of examples:

Learning to Extract Flawless Slow Motion from Blurry Videos
Blurry Video Frame Interpolation

The picture below is from the second paper.

However, as of this writing, I couldn't find any feasible-to-use, (commercial or otherwise) software to achieve that.
You could actually use the techniques above to apply it to your video, since they even offer the code on Github, but it would be a great effort, you'd need to basically build a video processing pipeline script/software for that.
It probably would also be somewhat computationally intensive (slow).
