import matplotlib.pyplot as plt
import numpy as np
import matplotlib.animation as animation
from matplotlib.animation import PillowWriter

fig, axis = plt.subplots()

X = np.linspace(1, 10, 100)
Y = np.sin(X)
X_len = len(X)

def update(frame):
    if frame == 0:
        axis.clear()
    axis.plot(X[:frame], Y[:frame])
    axis.set_xlim(0, 10)
    axis.set_ylim(-3, 3)

animation = animation.FuncAnimation(fig = fig, func = update, frames = X_len, interval = 1)
animation.save("my_animation.gif", writer = PillowWriter(fps = 60))
plt.show()

This is my code. Can someone explain to me why the saved animation appears to be slower than the animation that shows up in the window produced by plt.show()?

discord's gif thing, tenor, hosts mp4 videos even though they're colloquially called gifs, because they loop and are have no audio

#

if you can't export directly to a video, maybe you can export frames, and then put combine them to make the video

I saved it as an MP4 file and it worked.
