I was hesitating whether to show the whole Posts on the main page or not. I changed subtemplate postformat.php from the_excerpt to the_content.

But I am not quite satisfied with the result, because my youtube videos are hidden in the main page and I think no one would click the button "read more" to actually view the video. Is there a way to show the video in the_excerpt in the main page ?

Or maybe manually decide whether selected posts are showing the whole content or the excerpt ?

I forgot my page address : www.projektowaniebim.pl

I would suggest creating a virtual sub-template called 'postformat-video' as a copy of the 'post format.php' sub template.

then change the line

	<?php bfa_thumb( 620, 180, true, '<div class="thumb-shadow"><div class="post-thumb">', '</div></div>' ); ?>

to

	<?php the_excerpt(  ); ?>

next edit the post, create a manual excerpt and set the post format to 'video'

Thank you. It worked
