What's New in Star Stacker

- Faster video creation: the video is now made during the main stack instead of afterwards. - Video export is now in 10-bit for smoother gradients and better colour (When your input files are high enough quality).

Keeps shutting down

Attempting to use the stacker on an iPhone 13 Pro Max. App continues to shutdown when you begin to stack. Not many options out there for an iPhone to stack.
