Do you know how to make a video to move one frame forward and one frame backward in media element in WPF. If you know please help me on it.

This is unrelated question. No, I did not ever try to address such problem, not sure media element is designed to do such things; cannot tell you anything more certain, sorry.

This is simple enough. For a image control's parent, use the instance of the class System.Windows.Controls.Canvas. Handle the events MouseDown, MouseUp and MouseMove of the instance of your moving control. For modification of location, use the modification of an attached property of the instance of the canvas for your moving object. This is as simple as using the methods Canvas.SetLeft(UIElement element, double length), Canvas.SetTop(UIElement element, double length) and the like, where element is your control you want to move:

Everything else is just pure logic of your code.
