Video motion
I saw the following youtube video,
I like the concept a lot but I only have ffmpeg
.
In the video we can make up five steps to extract the motion from a normal video
- set opacity to 50%
- duplicate video
- inverse colors on first duplicate
- time shift on second duplicate
- overlay duplicates
After some trial and error, here's the ffmpeg command I came up with to achieve a similar effect:
TIME_SHIFT=0.8
