hi, I run the script success:
python scripts/sampling/simple_video_sample.py --input_path assets/000.jpg --version sv3d_u

And i get the output in outputs/simple_video_sample/sv3d_u.
But the 000000.mp4 can't be played.

I check the origin result vid, this is valid. the problem maybe in imageio

[wzds2015]

confirmed the issue is from imageio. Switch to cv2 solved the problem. fix: #327
