hyperlapse/timewarp

Hello i had few weeks a gopro 11, and what i love at most is the timewarpe function...very fluid, nice.

Now i am trying to do it with my camera, a sony zv1, but wether i put a minimum distance among frame(1 sec) or higher one (2,3 sec..) i can never get a similar result

I am trying to undertand how gopro do this timewarp..but there are no info around..i have come to conclusion that it is a video  recorded at 10-12 or similar fps and then speeded up.

If someone know about this it would be very good, but meanwhile i would like to try to do that in premiere with a video already have, since no camera records at 12 or similar fps

So the idea would be the delete every other frame from a video, and eventually to speed it up

Of course it is not somehting that can be done reasonably manually

Is there any function or plugin  or other tool that would let me do somehting like that?

Or may be even another specific software?

thank you
