Could you please share the input video and the mediapy call(s) so that we can investigate? Thanks.

Please try including fps=24 in the media.show_video() call.
(The issue is that the video retrieved using read_video() is a simple numpy array without the framerate information.)

Programmatically, one can use:

with media.VideoReader('https://github.com/hhoppe/data/raw/main/video.mp4') as reader:
  fps = reader.fps
  video = np.array(tuple(reader))
media.show_video(video, fps=fps)

or

with media.VideoReader('https://github.com/hhoppe/data/raw/main/video.mp4') as reader:
  media.show_video(reader, fps=reader.fps)

This should be fixed in 21d54f3

Now the framerate should carry through even in the simple case below:

import mediapy as media
url = 'https://github.com/hhoppe/data/raw/main/video.mp4'
media.show_video(media.read_video(url))
