Yes blank screen and talking is fine enough. Check out the above link. Its best to tell a story, something along the lines of the problems in your target customers life without your product, then how much better it gets once he has your product.
Keep it short <2 min and just cover main benefit/feature.
If it need to look more flashy for an investor or something use an adobe after effects template from http://videohive.net/ and you can prob find someone on fiverr or similar site to edit it for you.
Remember it just has to be interesting to your target customer, so don't make it about your product make it about them!
