使用python将GIF转换为mp4

Question

目前我正在尝试将一些我下载的GIF转换成mp4文件，这样我就可以将它们上传到特定的网站。然而，当我尝试这样做时，我得到了一些错误

    for submission in subreddit.top(time_filter="day"):
    url_file = r'/home/pi/Desktop/Instagram/urls.txt'
    # Get the link of the submission
    url = submission.url
    if url.endswith('gif'):
        bad_chars = ['"', '*', '?', ':', '<', '>', '|', '\\', '/', '.']
        for i in bad_chars:
            submission.title = submission.title.replace(i, '')
        count += 1
        print(url + ' ' + submission.title)
        urllib.request.urlretrieve(url, r'C:\Users\myalt\OneDrive\Desktop\TikTok twitch poster\Clips\\' + str(
            submission.title) + '.gif')
        print(str(f'downloaded {count}'))
    for file in os.listdir(r'C:\Users\myalt\OneDrive\Desktop\TikTok twitch poster\Clips\\'):
        clip = mp.VideoFileClip(rf"C:\Users\myalt\OneDrive\Desktop\TikTok twitch poster\Clips\{file}")
        clip.write_videofile(f"{submission.title}.mp4")

错误：OSError:MoviePy错误：无法读取文件C:\Users\myalt\OneDrive\Desktop\TikTok twitch poster\Clips\n的持续时间我的朋友声称他可以用他的3D打印机打印枪，但我对我多年来使用Canon打印机不感兴趣。gif。 以下是ffmpeg返回的文件信息：
