Not sure if there's meant to be white dots near the children's white shirts (kinda like a glow)

And I can't tell if the bricks are meant to look like that due to film grain.

I see no dots, only the fact that whoever captured or digitized this clip got the white levels seriously screwed up and ended up blowing out the highlights. It is possible that your media player may be showing artifacts (I used VLC which showed no dots) as a result of those illegal white values.

Yes, the whites are blown out. Even the black levels aren't all that good in places of the sample. You can fix the whites using something like this:

Tweak(Bright=0,Cont=0.9,Coring=False)

I don't know how much work you want to do on it, but in plces that brings the blacks down closer to being good. In others it crushes them a bit.

Put this on before adding in the Tweak command:

ColorYUV(Analyze=True).Limiter(Show="Luma")

The green places are where the whites show illegal values. The reds are for blacks that are too low. After adding Tweak, the whites are okay but sometimes the blacks go too low.

I don't see any dots, either.
