It's been awhile since I tinkered with improving the actual quality with videos I embed on my site hosted by YouTube. A few years ago a simple url add on made them look crisp and cleaner. Now the embed code has changed and these add ons don't work anymore.
Ones that worked successfully in the past..
&hl=en&fs=1 (Offers HD Option)
Incidentally I'm getting flickering pixels in portions of the video and the reason for finding a new fix. Works fine in IE (albeit a bit cloudy) but not other browsers.
Any suggestions? Final render in my video software looks fine.
