Agree with other posters that the white streaks are not shooting past the camera craft, rather the camera craft is coming up on marker trails from bombs dropped by one or two aircraft just ahead. Also agree that the black puffies are flak bursts.

One of the “related clips” lists the target as Ludwigshafen, and Google Earth confirms this. Ludwigshafen itself is on the “near” side of the river. There’s enough white stuff there to suggest another bomb group had passed over previously. Anything that goes into the land in the bend of the river, the river itself or the far bank (garden allotments!) has overshot.

The marshalling yards in Ludwigshafen are below the camera craft very early in the piece and run perpendicular to the line of flight.
