Player - Filmstrip App

	Filmstrip Video Player is a simple video playback app which allows user to build filmstrip of the currently opened video without playback interruption.     Each slide within filmstrip can be saved as a file in the variety of different graphic formats; each slide or even all slides can be removed from filmstrip and all these slides manipulations don’t affect video playback.     All the slides within filmstrip are filtered by the corresponding video frame time stamp; selected slides show their time stamp in red.     Plying back video can be positioned by the selected within filmstrip slide.     Slides can be created manually from the current video frame or automatically by assigning desirable slides amount or time interval between slides and positioning precision; automatic slides creation can be stopped or cancelled.

	Main (bottom) control bar visibility is controlled by right mouse click (press and hold) on the app itself.     Main (bottom) control bar size controlled by click (tap) on the ellipsis [•••] located on the rightmost site of the bar.
