I'm in the planning phase for a project and was wondering if it is possible to dynamically blur video using the blur filter? Specifically, I want to:
1) Stream an flv file, and apply the blur to the left and right edges of the video, so that they become clear on mouseover.
2) Blur the whole video, and have only the region closest to the mouse pointer clear, which will follow mouse movements.
3) Feather the blur, from blurred to clear
What sort of additional system resources does the blur filter require? Will it increase the swf file size much?
Thanks for your help!
you can certainly blur an flv by blurring the flv's player. but i don't know how you would feather a blur.
and filters increase cpu utilization and not much file size.
Thanks for the quick reply kglad. So is there no way to have a gradual blur? Does the area to be blurred have to have crisp edges like http://imm.sheridanc.on.ca/imm2006/alducent/tutorial/blur.html ? I really need to have the region that follows the cursor to be in focus (showing the flv behind), and then have it gradually blur more and more the further away from the cursor.
i don't know of any way to use the blur filter to create a gradual blur.
you can create a gradual/feathered blur effect by using the bitmapdata class but this would be a task for someone comfortable with the bitmapdata class and actionscript coding.
