Tonight there was a nice thunderstorm here and I was enjoying the view with 15-30 flashes in the sky every minute. I did a movie with my phone and there are a few real nice flashes captured, now I would like to extract some frames to be able to show them as a picture. Making a screen shot is one way but I would like to be more exact and maybe get a little better quality by extracting direct from the movie. (Not that the video quality is that good, i filmed through the window, but it's fun to try anyway)
Edit: I found that it's possible to extract images with ffmpeg, but that will not be that exact, I think I need to pic a specific frame from the film. The film is an .mp4

Have you tried vlc players option "video" -> "take video snapshot" or however it's named in the english surface?
works fine here.

I tried with vlc but I cant find a way to go from frame to frame, I am not able to stop the video at exactly the right time (frame)

I have the german surface here, so my translation may not be very good.
Goto "tools" -> "adjust surface" -> "time panel"
There you may get the options to slow down the movie or even set the frame to frame option.

I did find a way to enable a one frame by one button in vlc.
---->"View"-----> "Advanced Controls"
And yes, it worked to take snapshot with vlc.
Thanks :)

i think you can even try with some more expert tools like kino and kdenlive! Anyway, good result and nice picture!!! ;)

You could do that also from within avidemux.

Why not just mpv:
Usage: mpv file
Options:
-fs => Fullscreen
--loop=inf => play it again and again ...
While playing:
Pause Video => space
Slow down => [
Speed up => ]
Set loop point A => l
Set loop point B => l
Frame by frame (forward) => periond (.)
Frame by frame (backward) => comma (,)
Screenshot => s
You can edit ~/.config/mpv/input.conf to change default keybindings.
