The preview image overlay is stretched to fit the embedded space whether it is in portrait or landscape orientation (you can see that the preview is stretched wide on desktop devices). The CSS for this is coming from the video host and not the Google Drive Embedder viewer.
Would you please send us an email to contact [at] wp-glogin [dot] com so we can arrange to get some login credentials for your clients site and Google Drive for the developers to take a look at this and the iPhone video play issue in the other ticket.

Sorry for the delay—I do not have a solution as of yet. The issues (both the distorted preview and mobile play button) have been reported to the developers for investigation and possible bug fix. Will keep you posted as I hear back from the devs.
We’re happy to pay if there’s a cost involved to get this prioritised and pushed through quicker. Let me know what your developers say as we’re very keen to get this website launched and we’re just waiting on this glitch to be fixed in order to go live.
Hope you can help
The developer has been working on debugging this but hasn’t been able to reproduce it with their own environment. I’ll check in with them to see if there is anything else they need that could help get this resolved for you.
