Ian, don't take this as a dig at you because its far from it, more of an observation.
I took a look at both your videos and was wondering if this type of video was going to be like an introduction to a longer video?
My reasons for asking are simple, video's just like flyer's, if you don't catch the custy's attention straight away, there not going to watch them?
As a w/c I watched them but from a custy's point of view, there going to be boring.....Why? because they don't want to see fast clips of our vans or other peoples windows.
I noticed a couple of clips of before and after cleans, Now these are better but slow these down by a second or two and it may just catch there attention, enabling them to see what results they could expect from our work.
Different types of buildings and windows that are being covered by the guy's on your website.
I know there only test video's but just a couple of pointers the help you produce a video for the customers and not for the w/c.
Good luck in your productions.
