Where is the play modes?

App says choose from 4 play modes but I only see one. I dont see where I can reverse the video or anything. I already have picplaypost so I didnt really even need this app. I purchased it for the REVERSE MODE which I do not see

UPDATE! There is a reverse mode but what I dont like about it is that the video has to be recorded from the app in order to play in reverse mode. I have a ipad and dont record videos from it, I record from my phone (HTC ONE) then transfer the videos I record to my camera roll. Add the ability to play videos in reverse from camera roll stored videos and Ill give more stars.
