Trying out the new video function

While preparing another post, I noticed, that there is a new video function on Blogger. Well maybe it's been there for a while, but I just noticed it so it's new for me! So I'm trying out this function with this video from a Sunday hike with my friends, Mirjam (blonde) and Hanna (brunette) at Feldsee in the Black Forest.



so, I haven't figured out how to turn the video yet, since I had turned it in a program on my computer and it looks right here. I don't know what the deal is...
