python 写入网络视频文件很慢_用Python的moviepy剪视频，为什么视频的写入速度非常慢？...

为什么程序在运行几秒后视频写入速度变得特别慢。

下面是全部代码了

from moviepy.editor import VideoFileClip

from moviepy.editor import CompositeVideoClip

from moviepy.editor import concatenate_videoclips

import xlrd

#文件路径

path = ".\\sources\\{}"

word_art_path = path.format("art{}.mov")

source_path = path.format("{}.mp4")

op_path = path.format("op.mp4")

ed_path = path.format("ed.mp4")

logo_path = path.format("logo.png")

result_path = ".\\results\\{}.mp4"

def fun1(sources, logo_size, logo_top_distance, logo_right_distance, art_one, art_two, art_four, art_five):

#加logo、花字

import moviepy.editor as mp

clip = VideoFileClip(sources)

clip1 = VideoFileClip(word_art_path.format(1), has_mask=True)
