Quick of overview of SkyBox 360 Post Fx for Adobe After Effects by Jason Bowdach (cineticstudios.com)
SkyBox 360 Post Effects are specifically developed for 360° footage: Blur, De-Noise, Sharpen and Glow. They will apply perfectly onto stitched 360 footage, across the seams.
This avoids the problems that can arise with some 2D effects, which do not apply smoothly across the seams where 360° footage is stitched together.
