I really like these effects and I would like to reproduce it.
I would like to point that I don't know how this effect is called. Whether it is made within a camera or in post production?
Here is 2 videos that have this. They are not identical but I think they are quite similar. I like how the video has some kind of distortion.
In the first video it is like fast forward with a lot of camera movement. You can see it starting from here
In the second video it is like fast forward but is slow motion. The effect can be seen when the drummer is in a frame.
So my questions are:
If it is in camera effect how is it made?
How to achieve it in video editing software?
