PBJVision
'PBJVision' is an iOS camera engine that supports touch-to-record video and photo capture.
It supports both iOS 6 and iOS 7 as well as 64-bit.
We created this at DIY.org as a fun means for kids to author video but also as a way to easily create stop motion. This same recording interaction was pioneered by Vine and later by Instagram.
