The length of video excepted varies from site to site, with Shutter taking up to a minute and Revo as low as 20 seconds. I hate to create different version just for different sites. The max I submit is 30 seconds... does anyone know where the sweet spot is for sales... 15 second, 20 second, 30 second or higher length clips?
Not all clips can be 30 seconds due to the nature of it, but know for instance if 20 second is enough, then I could submit that to all sites without worrying about length...
