If you saved the files locally, you can view them by taping the Library icon. If you don't see them immediately you can then tap "View Local Files" at the bottom of the window. From there you can tap the 'Select' button to select the video and then tap the Share icon (lower left corner) and then copy the selected video file to your photos library.
If you are saving videos locally it is highly recommended to toggle that off so that the videos go immediately to the Photos library without doing the above steps. (Plus you won't lose any videos if you ever delete the ScoreCam app.Tags: photos library, saving, videos
