Hummingbird minify Distorting video

Video thumb is showing small within the video player on my home page when Hummingbird Asset Optimization is activated. It is still the same if I disable modifications for all the files. When I disabled Asset Optimization it shows correctly, and when I checked the site using unminified option at the top bar it shows the video correctly as well.
Have disabled all the other caching and also cleared caches, but nothing helps.
