Praise be to Allaah.
Videos, radios, TVs and other media equipment are in and of themselves neither halaal nor haraam, because they are merely machines. The ruling is based on whatever it is used for. If it is used mostly or solely for haraam purposes it is haraam, otherwise it is halaal. On this basis, if the video is to be used only for good purposes as you state, then it is good, otherwise it is bad. And Allaah knows best.
