The content plugin for Videos is distorting image aspect ratios. At least in JA Blockk. Videos are all typically 16:9 and our images are 16:10, or 4:3. They are getting stretched or squished.
We fixed the issue by adding object-fit:cover to the CSS .
This issue is present on the JA demo site for Blockk on the video content page. It'd be nice to update the content type plugin / CSS so that images are cropped /resized properly to match the 16:9 video.
