Making accurate and smooth hyperlapse

Hello amazing forum.
I’ve got few gigabytes of FullHD H264 avi video at 30 fps which is essentially dashboard camera footage from long 1000 miles road trip in a car.
I want to do make a hyperlapse out of this video – by dropping most of the frames in regular intervals, let's say leaving in the footage only 1 frame out of 10, and then removing gaps and speeding up remaining image sequence to 60 fps or so.
Virtualdub does very dirty job (not smooth and choppy, seems not dropping frames evenly), so I am trying to explore avisynth to see if it can be done nicely on Windows PC.
Asking for help with following:

1. Can this be done with avisynth, in principle?
2. Could someone please guide me with script creation for such video decimation and acceleration?

Video stabilization can be done in virtualdub (deshaker plugin) very easily, so it is not part of the question.

Thank you!
