This adds to slower mobile scores on Insights.

Hello D.C.,
I see that your image is 1920×1080 pixels and 75 kB. Most mobile phones are about 390 to 414 pixels wide. I see that a 800 pixels wide image (I doubled the number of pixels to make it retina) could be about 20 kB in size as WebP.
We plan to improve that in the upcoming FV Player 8 which some users are already beta testing.
I also have to add that the image optimization recommendation of PageSpeed seems to favor images with too high compression.
Thanks,
MartinThx… Yeah, there’s is no swapping to small images on screen size changes. I wasn’t sure if this was a theme issue or a player thing. It’s my last hurdle with page speed…
Hello D.C.,
We worked on this feature for the upcoming FV Player 8. Any image that has been inserted via WP Media Library will get the responsive image sizes.
It did improve our mobile PageSpeed scores by 8% and First Contentful Paint (FCP) was lowered by 35%.
Details
For our test playlist with 5 videos it decreased the total size of transferred images from 775 to 140 kB on desktop and from 774 to 667 kB on mobile.
The savings are not as big on mobile as it typically has a retina screen and higher resolution images are loading.
The PageSpeed scores on desktop did not improve much as they were 98 even before, although the First Contentful Paint (FCP) and Largest Contentful Paint (LCP) went down from 0.6 and 0.9 seconds to 0.3 and 0.8 seconds.
On mobile the PageSpeed scores improved from range of 80 to 85 to a solid 89. The FCP went down from 2.0 to 1.3 seconds.
It would also not complain about “Serve images in next-gen formats” and “Properly size images” so much anymore.
Thanks,
MartinSo nothing to do until FV 8? Any functions I can add to my functions php file to address issue until the new version comes out?
No, but you should be able to get access to FV Player 8. Martin, please give DCD access.
Thanks, Alec
