Longer videos are just showing a grey screen as the thumbnail and no video controls. This is happening for videos over 50 minutes on our website. Example video: 


When I disable the ARVE plugins the thumbnail shows fine. This is what is looks like:

When I Deactivate just the ARVE Pro Addon the thumbnail and video loads fine.

The page you liked shows a specific Vimeo embed with the ?title=0&byline=0&portrait=0 parameters that hides controls and title. Its done without ARVE and I do not see any grey thumbnails. If you want help give me a page where I can expect the problem where ARVE is used.

I do not understand what your screenshot is showing but generally screenshots to not help.

Here is a video that explains more of what is happening and how it is fixed when I deactivate the ARVE Pro Addon Plugin: https://www.loom.com/share/aedeeb10e15b465f9c58c8ffd7099c95

Thanks for the screencast, but yes please give me login info so I can inspect he code. Yes the default settings URL parameters are fine and do not cause this, however the link you showed above seems to have a vimeo video with parameters that remove the controls but seem to be unrelated to this issue. There is a lot going on on the page you show, like accordion, other videos … can you create a single page with only that video and see if it happens there as well? I created a test page here https://nextgenthemes.com/vimeo-test-ryan-wakefield-grey-thumbs-issue/ and it works perfectly fine here, may have something to do with the accordion or that the video is initially hidden. Is your default mode set to lazyload mode?
