The QR code is a great way...and essentially the same thing..however there is something cool about seeing the video being played right in the area that you mark as the ad. For example, I could have a signVOX ad in SDGMag then in this viewer have just that area play my demo (hahaha...one day I swear) of the software. That presentation is more WOW than the link to the video albeit the same thing.
I see where this might be good in print ads. However, for Real Estate
signs your going to have to mark out the same area as a QR code and then hope the public is educated enough to 1. know what the heck it is 2. have the program to actually use it. 3. Actually own a smartphone. Sadly, most home buyers in the current economy don't own a smartphone and those that do don't know how to use them properly.
In 10 years maybe this will catch on but, given my experience with buyers/sellers and realtors this will be a heck of a hard sell till then.
I spend 10 hours a month just teaching Realtors how to use their smartphones to put QR codes to work. Now your going to throw something more complicated at them it just won't compute for the majority.
