It's graduation season so I thought I'd share this simple Shortcut. It's for those of us that accidentally switch to video mode on the iPhone camera when we are trying to just take a photo. I did this recently and ended up creating several one second videos when I thought I was just taking photos.
The Shortcut shows a photo picker and then converts any selected video to a JPG. The first frame becomes the image, which may not be the best photo but at least it's not a one second video.
