A video isn't going to show much of anything (especially since we don't see the setup in it), because for FPG your x position needs to be within half a pixel, and that's not something you can tell by just looking at an image.

In general, you want to find the rightmost subpixel that you can jump and not land on the flagpole block, which you can do by first finding the earliest frame that you do land on the block and then doing a LR wiggle in the air until you don't land on the block anymore. Then L, nothing, R, L+A, nothing, R should get you the FPG. If it doesn't then release right at a different time as you're falling towards the pole and then it should work.
