Not external effects, but...
corner lens blur:
layers from the top:
5. masking layer, masking one layer below, a white solid color clip with a vignette effect (w BlackBG On ) and an InvertRGB effect
4. blur effect clip
3-1. content
Glow/bloom:
drop a blur effect, set the effect opacity to 50% set effect blend to Luma Is Alpha.
Or for better results, drop a levels effect to a clip slot, and drop a blur onto this clip, and set the layer's blend to 50% luma is alpha. Adjust Levels effect so image has more contrast.
