One of the websites I am building for a client has several video clips (she is an opera singer). Of the five videos, one of them does not display a preview image before played; this is only a problem on some computers, all with different internet connections. All you see for that video is the gray bar with the play button on it until you push play and then the video pops up. You see straight "through" the video before play is clicked on (you can see the background color of the section). This video is not the largest of the five videos that are on the page, but it is the only one having problems. I tried deleting and re-downloading the video and moving it around on the page. This is actually a problem on my client's laptop, but not for my device so it is also difficult to troubleshoot.
I feel like I must be missing something obvious. Does anyone have any experience with this or know what might be going on?
Thanks in advance!
