添加圖片水印
import moviepy.editor as mp
#本地視頻位置
video = mp.VideoFileClip(r"D:\resource\myresource\4393644710024974337.mp4")
#准備log圖片
logo = (mp.ImageClip(r"C:\Users\zrail\Downloads\touxiang.jpeg")
.set_duration(video.duration) # 水印持續時間
.resize(height=100) # 水印的高度，會等比縮放
.margin(right=8, top=8, opacity=1) # 水印邊距和透明度
.set_pos(("left","center"))) # 水印的位置
final = mp.CompositeVideoClip([video, logo])
# mp4文件默認用libx264編碼， 比特率單位bps
final.write_videofile("test.mp4", codec="libx264", bitrate="10000000")

添加文字水印
# -*- coding: utf-8 -*-
from moviepy.editor import VideoFileClip,CompositeVideoClip
#本地視頻位置
from moviepy.video.VideoClip import TextClip
#subclip視頻截取開始時間和結束時間
video = VideoFileClip(r"D:\resource\myresource\4393644710024974337.mp4").subclip(0,1)
#制作文字，指定文字大小和顏色
txt_clip = ( TextClip("zxl shuiyin",fontsize=30,color='red')
.set_position('center')#水印內容居中
.set_duration(1) )#水印持續時間
result = CompositeVideoClip([video, txt_clip]) #在視頻上覆蓋文本
result.write_videofile("tttttest.mp4",fps=25)#fps:視頻文件中每秒的幀數
