wow tom's... that was pretty rough.
1) simplicity is best. Seriously, go look at anandtech's video reviews. It is a guy, behind a desk, talking intelligently with a few product closeups when needed. The fake pad, the dumb background taking ~60% of the screen, the charts/graphics, and the flying hand cuing the transitions are all distracting, and unnecessary. It makes it look like a highschooler threw it together.
2) Honestly I do prefer to look at/listen to a woman, but above gender I would rather listen to someone who speaks intelligently and authoritatively rather than someone who over enunciates and (due to ignorance or stage fright) does not seem to know what they are talking about.
3) Frame rate issues. Be sure to match your video and digital content frame rates. It made for some shotty/jumpy transitions. Best just to do a simple video feed with the occasional informational overlay instead of trying to do what you did.
4) Visual theme. You need a set that is unique to your site that borrows from the long standing motifs that your site uses (like the hammer, perhaps a red/black/white block theme to match the website) so that when people see your video (perhaps in a different context like on youtube) then they know that the video is from you. Having a different theme based around the product reviewed for each video is both time consuming, and difficult to brand.
5) player. It is hard to find a good player, but generally something small/out of the way is best so that it focuses the viewer on the content instead of the player itself. Not a huge issue, but your player looks a little old, and is oddly tall for a wide screen format. Look into jwplayer or the youtube player as good examples to aim for.
6) Audio is 9/10ths of video. A little background music, or at least an intro theme would spice things up a bit. It does not need to play throughout the video, just an auditory cue to 'pay attention' at the beginning and end would be fine, and add a little polish. Also, her voice sounded a bit thin on my laptop. It may be different on some real speakers, but finding someone with a fuller/more interesting voice may be a good way to go. Or doing an EQ on her voice, or using a better mic could also help with that, but too much audio editing can make things sound unnatural and distracting from the content presented.
7) Header/footer. While some people find headers and footers annoying it does help with branding your material. A simple 2-5sec intro (look at newegg as a perfect example) is a great thing to do. this also serves a purpose of letting people tab back to the page if their internet or your server is running slow so that they know that the video is done loading. The footer is more just for credits and pointing people to other resources, but can also be useful.
All in all I am a big fan of moving to video reviews as they feel much more interactive, but it is going to need a little work if you are going to make a habit of doing this. Videos have not exactly been your strong point in the past either.
