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
