Frame Player is an advanced video player that let you see a recorded video at several playback speeds maintaining audio synchronization, play frame-by-frame, zoom-in any part of the video, and save frames as images to the device storage. Just select a video from gallery or record a new one from the App, and press the “Start” button to open the player. You can enable a brief tutorial about the player controls, and disable it when you want.
Frame Player automatically calculates video framerate (frames displayed per second) for the frame-by-frame playback. If you consider this calc is wrong and you know the right value, you can set it manually.
Known issues: running over low-end devices with Android Lollipop, slow and fast motion may not play smoothly.
