Thanks Steve for your reply,
So I went back to investigate this further, and here’s what I found:
- Your 8th to last video generation was the last one that used the Veo 3.1 Fast model, which just as you mentioned , it consumed 40 credits. At that point, your balance was 1,630 credits.
- After that, you generated 7 more videos. None of those used the Veo 3.1 Fast model; they were all created with the Firefly model, which uses 250 credits per video.
That means after your balance showed 1,630 credits, the next 7 videos used a total of 1,750 credits. This brings your overall usage to 4,120 credits across all your generations.
If you want to double‑check everything, you can go to Your Stuff → Generation History, then select Video, that will show all your video generations and help you keep track of your credit usage.
Let me know if anything here needs more clarification.
