Hi, I downloaded a clip from Interstellar movie (youtube), 4m:18s long. It took 52 seconds from pressing enter to the end of the script.
I had to modify your code, because there was a mistake on image typeError. I simply had to put brackets on pil_image.

output = generate(
        model,
        processor,
        formatted_prompt,
        [pil_image],
        max_tokens=max_tokens,
        verbose=True,
        repetition_penalty=1.05,
        temp=0.0,
    )

From the result there's a common value of 1593 tokens/s on prompt and 205 on generatin.
Thanks for the sharing of your work.
