Poster Image Size

Right now all generated poster images are the same resolution as the video, so if you have a 1080p video but show it in a 640×360 window the poster file will be unnecessarily large. On the other hand there seem to be people using posters as images separate from the video and may need the larger size. I think in future versions I will try using the “medium” image size for the poster instead of the full size. You can do that yourself by changing the poster attribute from something like poster="http://www.yourwebsite.com/wp-content/uploads/2013/02/video_thumb42.jpg" to "http://www.yourwebsite.com/wp-content/uploads/2013/02/video_thumb42-730x410.jpg" (the file name will vary depending on your own “medium” image size which is set at /wp-admin/options-media.php)
