export_to_video issue

[lucken99]

This issue is coming, it was not there yesterday:

ValueError Traceback (most recent call last)
in <cell line: 10>()
8 prompt = "Spiderman is surfing"
9 video_frames = pipe(prompt).frames
---> 10 video_path = export_to_video(video_frames, output_video_path="./spidey_surfing.mp4")
11 video_path

/usr/local/lib/python3.10/dist-packages/diffusers/utils/export_utils.py in export_to_video(video_frames, output_video_path, fps)
130
131 fourcc = cv2.VideoWriter_fourcc(*"mp4v")
--> 132 h, w, c = video_frames[0].shape
133 video_writer = cv2.VideoWriter(output_video_path, fourcc, fps=fps, frameSize=(w, h))
134 for i in range(len(video_frames)):

ValueError: too many values to unpack (expected 3)

May be because video_frames[0] has shape = (16, 256, 256, 3)

Problem with main but stable is working fine

Hi @lucken99 could you please share a code example so that I can reproduce the error. We recently merged #6626 that could cause this issue.

It's there in the post itself while calling pipe.
You can check the full code here:
