I have created a short video and done it the same way, (I think), as other videos for 'Averingcliffe'. When I go to view the video on YouTube, the audio is there, but just a white screen. I have had a quick search on the help pages without finding a solution but will look in more depth tomorrow. In the meantime, does any one know an obvious thing I am doing wrong, or a quick fix? 

Does the original file on your PC play ok?

@ntpntpntp  Well I have just gone back to the shortcut I created on the desktop and there is nothing there! I have gone into 'VideoPad', where I created the initial video and it does not now exist. It was definitely working when I was playing it back earlier, so what I have done, I do not know. It looks like I may have to try and create the video again. 

I have just created a new video, without any additional audio and it has uploaded to YouTube no problem. 
I have added the clip to the 'Show your Latest Loco and Rolling Stock Purchase' post.
