Handball rules: Mass confrontation in cup endgame

Three seconds before the end of the (first) overtime and at the score of 33:33 there is after different fouls in the execution of a free throw a mass confrontation and a few (partially narrowly prevented) assaults. How many players of the red team and how many players of the black team are there on the playing field? Also pay attention to the intervention of the referee in the foreground and the comments of the hall speaker.

This was punished with "only" two red cards.

The video lasts quite long with the repetitions and slow motion. In reality, it took almost four minutes from time-out 22 seconds before the end of the game to the execution of the direct free-throw.

Unfortunately, the video quality - recorded with my first SD camera - is appropriate for the time; the game was almost 10 years ago. This must also be taken into account when evaluating the rules.
…
Not least because of such situations as in the video the rule 8:10 was changed several times and (last 2018) adapted.
…
Oh yes, after the second overtime team Black won with 39:38.

Maybe I should upload a compilation of this game; I think it would be worth it - despite the poor video quality. My at that time 15 year old son wrote a live ticker for this game. The last sentence in this ticker was "THE BEST PLAY OF MY LIFE!
That's how I see it as a much older handball player, too.
