VEO 3.1 - Last Frame Parameter Not Supported

Gemini API
, ,
1

Hi everyone,

I just tried the newly released VEO 3.1 model (veo-3.1-generate-preview), specifically using the first & last frame control which is great.

I literally used the code from the documentation, and also tried to copy the code from AI studio demo.

Unfortunately every time, I end up with the following error. Feels like the last frame parameter isn’t actually implemented yet.

Anyone experiencing a similar problem?

Cheers

Yes, same here in Javascript. Only works without the lastFrame. Also tried uploading the lastFrame as image first with the files endpoint, but alas….

The documentation explicitly says it only works with the model: ‘veo-3.1-generate-preview’

Have you solved in some way? I have the same error when I use lastFrame parameter.
