simple motion graphics video

[JensenBreck]

Hello,

could someone give me advice ? I've got a simple motion graphics video in my portfolio
The only thing is that as it starts blank the thumbnail view is blank.Is there any way of having the thumbnail show some of the elements or perhaps a snapshot of the end, as they do at FT?I Any advice? .I went through many resources and also checked motion graphics videos but did not get anything important.

Any help will be appreciated.
Thank you.
