Wistia have just launched their new video player (beta) which includes thumbnail previews when you scrub, as well as variable playback speeds (0.5x>2x). 
For users that would like to listen to the dialogue parts of the video at half-speed, this is a great addition to the player.
Let me know if there are any older videos you would like updated with this beta player, and if you have any problems playing the video.
