Question

J'ai mis 2 images 16.9 avec le modèle Firefly video et Veo 31.1 fast, le rendu est visible mais après le téléchargement sur sortie MP4, l'écran reste noir. Quel modèle faut-il utiliser pour voir le rendu final sur MP4 ?

    I did not understand your answer. I asked to generate an image of 8 sec with a first resolution of 720 pixels, then a second one of 1080 pixels. For the first one, the character does not smile, and for the second one, the character smiles, even though the prompt is exactly the same for both. Can you tell me why the AI is not able to generate the same images but at a different resolution and with a smile? Kind regards, Eric GILLES HBS FRANCE

    Hello Kartika, Thank you for your response. So, according to the general settings, there are several models. Which model would you recommend to me, with a resolution of 1080, a first image and a second video image and for a video output in mp4 please? Kind regards, Eric GILLES HBS FRANCE

    Other question 2: I ran a test with two images—one at 720 pixels and the other at 1080 pixels, in VEO 3.1, with the same prompt, and I noticed that the result is not the same at all. For example, in the second output (1080p) the character smiles, but in the first one (720p), the character does not smile. Is it normal? Kind regards, Eric GILLES HBS FRANCE

    What was your prompt? Did you post to have the subject smile?

    Hi GILLES!

    It is not a normal behavior. Does it happen while using specific reference images? I tried and not getting the same issue. Could you share images that you’re using for adding frames?

     

    Let us know. Happy to investigate.

    Thanks,

    Kartika
