Francis Lawrence music video effects

Would anyone be able to help me to understand what would have been done in post production to achieve the effects in this video.

Specifically the kind of 'halo' that is at 1 minute 50 secs to 2 minute and 2 secs (save you having to watch the whole thing!) It's throughout the whole video but I guess it's the same effect?

Also, when she is 'falling' (3:36 - 4:02) - practical effects were a fan and a black back drop but there is obviously some other filter or effect put on the shots. If anyone knows how this was achieved I'd much appreciate it.

Sorry I am a novice at this point. Any help much appreciated!

Lens flare.  From a third-party plugin.  There are quite a few.  Since this is a big-time video, it's probably the pricey ones from Sapphire.

Is this for the halo effect?
