This should give you a better idea of how to create a "time slice" image.
The red box on the right is an enlarged version of the red box on the left. Each slice is cut from a different photo in the timelapse.
For this one I used 7.7 pixel wide slices. To figure out how wide or tall your slice should be (depending on which way you want to orient the slices) you simply take the number of pixels your image is and divide it by the number of photos in the timelapse.
An easy way to cut the slices from each photo is to use the rectangular marquee tool in photoshop and set the style to "fixed size" if you’re doing vertical slices (like I’ve done above) set the height to the height of your photo and set the width to your desired width of slice. One click and it makes a marquee exactly the size you want, all you have to do is position it next to the previous slice each time, invert the selection (ctrl+shift+i for windows users) and delete the excess. Repeat that until you start to go crazy then take a break and come back to it later.
The effect looks a lot smother if you use smaller slices. I’d like to do one with 1px wide slices, but that would take forever! (I did one with 2px wide slices and it took about 6 hours)
If you have any questions, just ask in the comments.
