Video youtube shows big black stripes

Please check the insertion of the video from youtube. I have big black stripes, with top and bottom. I tried pasting through Shortcode and through youtube Insertions. Both options work poorly for me. The mobile version is worse than the rest. Photo Sample Shortcode with direct link to mp4 file works fine for me.
