Hello @Jeremy Blume
I hope my commemt catch your issue well, we have checked the video of the translation, we found that it works well on our side, only at low quality 8kHZ the word "当一家子人“”没啊“ returns with some electric noises, which is around normal at this quality and this speed.
But I have forwarded this issue to product group about when video speed is up, the quality of the output video is not good. I hope this will be improved in the future.
Thanks for reporting this gain and I hope my answer is helpful.
