I am trying to add a video clip into a sequence, something I have done successfully before, but am struggling.   The clip runs through as a series of static images, but I cannot get the video to play.   It is in MP4 format, and when it asks if I want to convert in order to allow smooth playback I have agreed, and saved in same folder, I have also tried saving to a different folder.
	 
	I usually go into Objects and Animation, click on the video icon, choose file and then close.
	 
	All the settings are the same as previous successful videos,  
	 
	I have tried it on both my PC and my laptop, with the same result from both.
	 
	I do hope that you can help
