Filmmaker Cristian Dimitrius has shared some rushes of amazing footage of orcas (Orcinus orca) hunting Atlantic herring (Clupea harengus) baitballs. It was filmed recently off Tromsø, Norway.

Cristian filmed the footage in 8K (it is significantly down sampled in the previews) using a RED EPIC Helium in a Nauticam housing. The final footage will be released in January.
