There seems to be an issue with SSOA and other effects near the edge of the rendered output, so the developers added the "extra frame edge" to allow for an overrun of sorts.  The area inside the "extra frame edge" will be output to your selected resolution.

thank you for your replying,cpercer.but i didn't notice the issue or bug in the orginal version,so i feel sorry that i don't understand your meaning clearly.could you rephrase your answer again or explain it clearly,such as what's the render issue?And after i read your explanation, i did a simple test ,firstly, i export 2 video in the same scene and same angle,concurrently,use the same ssoa range and strength in random value,but use max and min value in "extra frame edge",after exporting them,i can't distinguish the differences between the two videos. Then,i did another test with exaggerated value in ssoa range and strength, in that case,i could make the shadow close to the screen edge,unquestionably,i also use max and min value in "extra frame edge",and this time i found a little differences between two videos,that is,the shadow caused by ssoa in first the video which with min value shows seriously flashing,by contrast,the shadow which also close to the monitor edge is showing normally in the second video. is this the render issue you mean?

When you use a large range of the SSOA you can see it fade in and out at the edge of your screen. You can remove this effect with overdraw. If you have a small SSOA range you don't need to do this. Also godrays (fog shadow) might be better if you have problems with it.
