A few years ago I wrote a python utility for interpolating a greater number of frames from a smaller set, for use in timelapse video/photography.

Recently, I’ve been trying to learn Julia. As a small challenge – to fulfil a potential forthcoming need – and because it claimed to be quite a fast language – I’ve rewritten the core of the script.

It’s quite refreshing – none of the gratuitous OO classes I had to create with Python, just a couple of functions to do the essential interpolation. And watching the output frames flash by… it’s pretty nippy, too.

It doesn’t yet support EXIF directly, nor can it modify images directly on the fly, but if you want to have a play then go download it from Github: https://github.com/spodzone/Timelapse.jl
