Kashav is basically right, but I'll elaborate a few more options.
Within NetLogo, your main options are:
1) have your turtles move faster
2) call the vid:record-view less frequently. Specifically, if you're using the tick clock to count up, then you could put in code like this:
if ticks mod 3 = 0 [ vid:record-view ]
which would make it so that you only save a video frame every time the tick counter is at an even multiple of 3. Then your resulting video should run 3 times faster.
After you've created a video, if you want to change its speed, then you'll want to use a 3rd party video editor.
Personally, I don't do very much video editing, but when I do I often use FFMPEG (https://www.ffmpeg.org/download.html#build-windows) It's a pretty powerful tool, but it's command-line only, not graphical, so you have to get comfortable typing black text on a white screen, and googling a lot for the appropriate commands to run. https://trac.ffmpeg.org/wiki/How to speed up / slow down a video
For something a little more user friendly, you might take a look at Avidemux (http://fixounet.free.fr/avidemux/). Here are some directions about how to change the "frame rate" to speed up or slow down a video here. https://filmora.wondershare.com/avidemux/how-to-make-timelapse-with-avidemux.html
However, other students may have better suggestions for video editing software than I do!
