In searching, I came across this that says Vimeo doesn\'t support it yet. But I was wondering if anyone has found clever ways around it still?

In your Vimeo account go to the video you wish to embed, then go to Settings > Embed. Once there enable the "Show Play Bar" option. This will eliminate the Play button in the middle of your video image, but will display the Play Bar at the bottom of your image. From what I can tell it's either/or. I would love to be able to hide both so you just see the clean poster frame of the video and click on it ti initiate playback. If anyone knows how please let me know.
