Please consider becoming a patron

If you like this project, please support my work by becoming a patron, and consider adding a 'star' to the repository. It takes a lot of time and effort to maintain the project and respond to issues. The cost of test prints, software, cameras, printer parts, etc. can quickly add up, so every bit helps.

I am running into this problem as well. No snapshots are being saved correctly. I am usually able to complete the video. I am also having issues with the stabilization not working fully but I think that is a different issue that I just need to work on my settings.

I was able to fix my image stabilization and can create a time-lapse, but I still do not have any preview snapshots.
