Re did the video and it created the same error it did the first time... lost 450 credits each time and still didn't result in what I asked at all

Generated a video for 450 credits.. it didn’t do what I asked, so I requested again and it didn’t change anything on the video.. lost out twice for the same issue.. before that I tried 10 times to generate the video with errors and lost 900+ credits on that too :( very disappointed in this video editing process
