Alternative Workarounds :

Try using an other html video player http://html5video.org/wiki/HTML5_Video_Player_Comparison

You can change you page background to gray for firefox etc. to match your video

Also if it's just the women talking you can use gif animation with audio

Capture Firefox :

Answer 2

In many cases it is a problem of nVidia drivers. NVIDIA video card users try the following:

1. open the NVIDIA Control Panel
2. under "Video" select “Adjust video color settings”
3. under "How do you make color adjustments" select “With the NVIDIA settings”
4. under "Advanced" make sure "Dynamic Range" is “Full (0-255)” not “Limited (16-235)” (“Dynamic contrast enhancement” should be unchecked)

In my case it worked, anyway I don't understand why Dynamic range for video is limited by default...

Chrome will default to a different video encoding using an open source HTML5 video codec.
The other browsers such as FireFox, Safari and IE will default to using Flash.
