Describe the bug

Hi @Weiyun1025, I notice that InternVL-3.5-1B-HF introduces an extra video_preprocessor_config.json compared to InternVL-3-1B-HF, in which some key parameters like image_mean, image_std, and size are inconsistent with the numbers in preprocessor_config.json. I was wondering whether this is normal, as to my understanding the images and videos share the same encoder and shall have the same sizes and mean/std parameters.
