Without access to the video (as it forcefully require to be downloaded), and as a generic information: the PostFX will "overly react" to the most emissive pixels; at low samples "hot pixels" / "fireflies" can occur in more areas than at high-enough samples and if remaining, several optimization methods are effectively applicable.
Could it be the reason?
When it comes to volume, in some situations the volume is more prone to these.
Perhaps, the Phase (scattering direction) is pushed too negatively?
