Firefly keeps replacing model when I am referencing the previous frame, seed and same prompt

 I have spent and waisted a lot of money buying and using credits that I can not use the outcome.  I am trying to use the same AI model in Firefly but it keeps replacing the AI model that I am using with a new model.  The generated video clips are 8 seconds long therefore in order to continue the video I have applied everything that has been suggested such as using consistent text prompts, and leverage features like Seed numbers and utilizing Structure Reference (for composition) for consistency; for sequential clips,  I have used the last frame of the previous video as the starting image for the next to maintain flow and style. 

There should be an option of refusing the generated video if it is not what you wanted.

I do not even know how to request credit for all the credits that have been waisted!  

Is there a version history? to see the exact settings I used previously?

Please

I’ve seen this happen too. Firefly will sometimes switch models even when you reuse the same prompt and seed if any settings differ even slightly — aspect ratio, style, or reference frame details will cause it to re-select a model.

A few things that help keep it consistent:

  • Make sure every setting matches the previous frame (prompt, seed, style sliders, aspect ratio, reference image).

  • Avoid using Refresh, since it forces new seeds — use Generate instead.

  • If possible, reopen the original generation link, since it keeps the exact seed/settings baked in.

Firefly’s seed system isn’t perfectly deterministic yet, so small changes can still result in a different model being used. Hopefully Adobe tightens this up in a future update!

Hey @Jackie37666555fcq8 

 

Could you make a video of your workflow? The team would, not me, need to see what is happening to be able to assist you better.

If it is changing to a different model, that should not be happening. A video of this happening would definitely help the Adobe team/ engineers.

Cheers

Nate
