Hi Marty,
videos are outside their view ports - whatever that means.
I wish to be Google employee, so that I can answer you in the only right way. But I am not.
Try to add right and left margin to Video addon (15px), it may help, at least helped me ones.
Here are three practical tips found on technology blog that could help you:
- Experiment with different video embed dimensions. Try to make them smaller, but not too small, because having tiny videos on your pages could impact the user experience. Technically, the lowest limit allowable by ‘Googlebots’ is 140px.
- Check video scaling – there could be an issue with an aspect ratio, when the width of the video does not match its height well. Note that in theory, this could be a matter of single pixels.
- Some users commented that changing video size in HTML code from absolute (fixed) values to relative values (expressed in percentage in respect to the screen size) may also work.
Nevertheless, the presence of this " error" should not affect the performance of the pages, at least according to Google. These updates are helpful for website owners looking to enhance their video indexing and search visibility on Google.
