This is some dummy text I am writing because it looks like stack overflow does not accept less description and more code. Please don’t mind these sentences. I cant believe that I am still writing this and it is still requesting me to add some more description. I am still doing it. Don’t know till what extent do I have to write. I hope this much is enough. -
FFMpeg video stopmotion
22 juillet 2020, par Praveen TamilI would like to create stop motion video from original video.
The logic is take frame at specified interval. 
And play the video with specified playback rate.



For example,

The original video duration is 114.048 seconds.

The output video playback rate 5 times faster than source video.

Take each frame at the interval of 1 seconds. so the final video duration should be (22.81 = 114.048/1*0.2) seconds


Below is the screenshot of demo



For this I need ffmpeg code



ffmpeg -r 1 -i D:\21-03-2018\15305154945b39d026a18da.mp4 D:\21-03-2018\output.mp4
