How do I get the best parts from a video? Status

I would like to do a gaming montage of my best moments (like this one).

Right now I have recordings with a total length of ~7h full of gameplay.

Problem

How can extract my best moments in a faster manner as watching the whole recordings without rewatching all my recordings?

Regardless if I speed up the recordings to x2 there are still >3,5 h to watch.
Racingfail did a video on how they cut the best parts of racing from other contributers: 
                
            
The general idea is the same as you have, but instead of seeing it at 2x, they do it at 16x.

Personally I use Davinci Resolve to skip though the video, with skipping 1 second ahead (shift+right), I see the stuff at ~30x. But any NLE has that functionality so go ahead!

If it's a recording you created, you might want to look at the waveform of the sound, if it's loud it's worth checking out (doesn't work if you have music going at the same time though)
