Video form another source, than youtube...

Hello,

I am back with another question.
I have articles, with video form another, than most common sources.
If I will add {SCOpenGraph video=http://www.stream.cz/object/798224-peklo-na-taliri-skryte-cukry} to my article, it identify video, but as I was expect, there is no image generated for that video. Just to notice, I use K2.
What exactly shall I do?

...can I use {SCOpenGraph ...} inside article, or shall I add it to another place?

Thanks for answer

//so actually I add another {SCOpenGraph image} ...and I am afraid, that it will be what I should do with all videos
...and another question, is more facebook, but I am no able to set-up it, length of description and why on my page show only title and not description, if put my mouse over title, open tooltip with description - or the description is taken from Metadata?
- problem is, that I try to do something and i am not able and in moment, when i add topic here, some ideas jump out

Hello,

I check again and it looks, that my set-up work with some delay. Now is exactly, what I set in administration.
If you want check it, here is link: www.fitspot.sk/ako-schudnut/zakladne-info/dieta
...there is some Scrap information and warnings - do you have idea, how to fix? ...is this information coming from Joomla, K2 or JFB?

Is it there any possibility to change how will be shown on Facebook? Normally there is on left picture and on right text, but if I "Like" page it show square with big picture and on right is only title, if I go with mouse over, show post as I want to have it.

Thanks again
