First of all: I worship you wizards of code really hard.

But now lets get to the Gaussian blur challenge. As you can see, the directional feature does not really work. It just changes the direction from NW to SE. Adobe somehow managed to let the pixels stay in place as in Justins blur preset with four directions.

Here is a comparison of three variations of one clip:

First is the rgba version from wwwmaze which was hardly playable in arrange preview. Rendering speed 0.2 real time

Second version is Justins YV12 version. Also hardly watchable in preview. But 0.4 real time rendering. As Justin mentioned. For some reason the colors are bleeding out the more you increase the blur.

And finally the Premiere pro rendering. The final blur amount is just a guess. Preview was also not possible. Rendering seemed as fast or a little bit faster then Reapers.

Many thanks for your work. Its just amazing to see what is possible. Gaussian blur is a beautiful effect with lots of possibilities. Reaper video becomes more and more professional. I really love it. (If there wouldn't be so much guessing for cropping, panning etc.)
