FFmpeg: Timelapse from Video, Speed Up vs Every n-th Frame

https://youtu.be/b4NtpGKK0ek

I go over two techniques in FFmpeg to turn a long video into a “timelapse”. One is to speed up the video. The second is to take every n-th frame of video. The second method simulates a traditional timelapse where you record a series of photos. I go over the pros and cons of each technique.
