Welcome to SPASM, the SPeedy way to create Assets for Stop Motion! 

I like to use stop motion animated sprites in my games. Prior to creating Spasm, that involved a tedious and time-consuming step in which I individually opened each frame of the animation in a photo editing program to shrink it down to a usable size and crop it to the right dimensions, then used a different program to make its green screen background transparent. Spasm is a bulk photo editor that allows me to edit all the frames at once. Even better, it dynamically creates a mock-up of the entire animation so I can see the effect of my edits in real time. Spasm runs as as a standalone executable. The edited photos appear in an Output folder with practical serial file names.

The best introduction to SPASM is to watch the tutorial video.

This is great, using it for my stop motion jam entry and saved so much time. Glad I paid for it as it'll come in handy in the future too. 

Do you mind if I put a link to this page on my game page as a great tool I used? Think more people should know about it. 

Thank you so much, both for buying Spasm and for the kind words! Feel free to put links to it anywhere you like. And as you use the program in the future, please let me know  any other features you wish it had so I can develop a new and improved second version. I can't wait to see your Stop Motion Jam submission!
