I didn't profess to being a professional video maker, this is only the second video I have made. As for the quality, youtube.com only allows a max file size of 10MB, the actual high quality file size is around 8900MB and therefore is much better.
As for the "low quality" stills, again this is due to the file size allowed by youtube.com. The lad who takes them is regularly comissioned by the RAF and RN to supply shots to them and produced the Jaguar retirement poster for RAF Coltishall.
But thanks for your comments
