PBJVision

Vision

Vision is an iOS camera engine that supports touch-to-record video, slow motion video (120 fps for supporting hardware, which is currently only iPhone 5S), and photo capture. It is compatible with both iOS 7 and iOS 8 but also supports 64-bit. Pause and resume video capture is also possible without having to use a touch gesture as the sample project provides.

iOS 6 is supported in versions v0.3.2 and below but may slowly start dropping support future.

I created this component at DIY as a fun means for kids to author video and share their skills. This same recording interaction was pioneered by Vine and also Instagram.

Please review the release history for a summary of the latest changes and more information.
