Irritated by the running about (20 second intro!) the glaces off-camera and the repeated 'erms', I stopped the tape at one minute, when you told me that 20% of ten-times £15 x 12 comes to "about £400" - Ouch!
The very core of your pitch is how much money I could save - yet you get the sum wrong. And not just any sum, but one that any technically literate person should be able to do in their head. The calculation boils down to 2 x 18 x 10 which, the last time I counted rocks, comes to 360.
(This whole thing is wasted on me, as, when MS went subscription, our policy of zero debt meant that forking out £15 per calendar month per workplace was out of the question. We have an absolute ban on subscription SW.)
Then you are giving away something from Google, but you do not explain what it is or why it would be nice to have one.
You have a good on-camera presence and unlike me, you have hair, which is always a plus!
Also, the more informal approach will work in your area and in IT generally and is to be commended, but I would lose any gimmicks that reminds me of the kiddie programmes on BBC Alba (apart from the brilliant Eòrpa, not a station to be emulated!)
Also you shot yourself from below and far too close up, which makes you appear threatening.
Shoot full-on, fairly loose and level, or very slightly from above. Never use a wide angle lens for a H-n-S shot!
A straight-forward head-n-shoulders to camera, perhaps with your workplace in the background, showing test equipment or similar gubbins to give the viewer the impression of technical competence.
On lighting, keep it bright and get someone else to operate the camera and lighting set-up. Remember that video flattens the face, in the same way that being on stage reduces the un-made-up face to a skin-coloured and featureless blob. On stage, we use make-up to sculpture the face. With a video interview,
we use lights to rebuild the face.
Cold (i.e. daylight or slightly blue) back-light and warm fill light is the usual setup.
Here's a brief how-to I found on YT -
When you are selling something, your video MUST be cheerful and bright - it ain't no horror movie! But you still have to sculpt the face back to life!
So in future,
when you watch TV, start to think about where they put the lights and how did they get that 'look'. In particular, look at US shows. British TV is usually very poorly framed and lit. Look at the lighting and framing for shows like Gotham and CSI New York. Think about how they got those effects. These are master classes in cinematography.
If you want to learn about lighting for camera, start by looking at the great masters of lighting and framing, such as Rembrandt, Vermeer, Turner, Caravaggio and in particular Edward Hopper. Suddenly, every scene in every movie will make aesthetic sense. You will begin to understand the how and why of the imagery and lighting in 'The Road to Perdition' or 'Saving Private Ryan' and even your simple head-n-shoulders pieces will (we hope!) improve greatly!
