the text2video result of 1.1 is worse than 1.0

[seeyourcell]

【1.1 version】
I use the gradio/app.py
prompt: # prompt_text = "A bustling city street at night, filled with the glow of car headlights and the ambient light of streetlights. The scene is a blur of motion, with cars speeding by and pedestrians navigating the crosswalks. The cityscape is a mix of towering buildings and illuminated signs, creating a vibrant and dynamic atmosphere. The perspective of the video is from a high angle, providing a bird's eye view of the street and its surroundings. The overall style of the video is dynamic and energetic, capturing the essence of urban life at night."

I use the same prompt ，with version 1.0 , I find 1.1 is worse than 1.0

length = "8s"
mode = "Text2Video"
aspect_ratio = "9:16"
sampling_steps =100
cfg_scale = 7.0

We identify the issue. The problem is that we apply qk-norm before applying position encoding. Thus, when we generate longer video (more than 2s), the image quality deteriorates. We will fix this in the next release.
