firefly videos

Hi!,

I have a problem with videos generated with FireFly. 8/10 are having serious artefacts and I have a feeling I had paid for mistakes not a solution.

Question: What do you suggest to promt in order to have good, nice, properly showed moving while generating sport moments. What should I write to have a good (any) sport moment. I see that there is the biggest problem with water and swimming.

maybe the problem is in language?

Any tips?
