Hello everyone , I am a J Brother .
Some time ago, someone wrote to me , Say you've worked so hard to edit a short video , After uploading to a certain platform , Because of the amount of play , received Right reduction The notice of , It directly leads to the invalidation of this account ！
Actually , Each big video platform has its own set of identification algorithm , For video Second creation , If you carry it directly , There will be some unknown risks
This article will take you to use Python Do some special processing for short videos , Make sure the video is originality and Uniqueness .
The following will be from MD5、 The light 、 color 3 To illustrate
The first 1 Step , Modify the video MD5 value
MD5 It's a cryptographic hash function , Of documents MD5 Value can determine whether the file has been modified
Use Python Self contained hashlib modular , Section read file , Can get the file MD5 value
① 200 Multiple copies Python e-book （ And classic books ） Should have
② Python Standard library information （ The most complete Chinese version ）
③ Project source code （ Forty or fifty interesting and reliable hand training projects and source code ）
④ Python Basic introduction 、 Reptiles 、 Network development 、 Big data analysis video （ Suitable for Xiaobai to learn ）
⑤ Python Learning Roadmap （ Farewell to bad learning ）

def get_file_md5(file_path): """ Segment read , retrievable md5 value :param file_path: :return: """ with open(file_path, 'rb') as file: md5_obj = hashlib.md5() while True: buffer = file.read(8096) if not buffer: break md5_obj.update(buffer) hash_code = md5_obj.hexdigest() md5 = str(hash_code).lower() return md5To modify the file MD5 value , Just append a string to the end of the file
def modify_file_md5(file_path): """ Modify the file md5 value :param file_path: :return: """ with open(file_path, 'a') as file: file.write("####&&&&")The first 2 Step , Brightness adjustment
Brightness adjustment , It's equivalent to adjusting the exposure of the entire video , Increase or decrease the light of the video
First , install moviepy Dependency Library
# Install dependency library pip3 install moviepy next , Increase screen brightness , Here are two There are two ways to increase video brightness
The first way , For every frame of the video , Adjust the brightness value
def handle_frame(image_frame): """ Processing picture frames :param image_frame: Picture frame :return: """ image_frame_result = image_frame * 1.2 # If the color value exceeds 255, Set it directly to 255 image_frame_result[image_frame_result > 255] = 255 return image_frame_result def increase_video_brightness(file_path): """ Increase the overall brightness of the video :param file_path: Source video path :return: """ video = VideoFileClip(file_path) result = video.fl_image(handle_frame) file_path_new = "/Users/xingag/Desktop/new.mp4" result.write_videofile(file_path_new) The second way , Extract video clips from files VideoFileClip, Use fx() Function vfx.colorx Parameters , Specify a coefficient , Adjust the brightness of the video directly
def increase_video_brightness2(file_path): """ Increase the overall brightness of the video 2 :param file_path: Source video path :return: """ # Adjust the value of the coefficient coefficient_value = 1.2 video = VideoFileClip(file_path) file_path_new = "/Users/xingag/Desktop/new.mp4" video.fx(vfx.colorx, coefficient_value).write_videofile(file_path_new) If you want to reduce the overall brightness of the video , You can adjust the above coefficient to less than 1 The number can be
The first 3 Step , Color adjustment
Color adjustment , Specifically including ： Hue 、 Color brightness 、 Saturation, etc , Here's an example of converting video to black and white
Again , Use fx() Function vfx.blackwhite Parameters , You can turn color video into black and white video with one button
def change_video_bhd(file_path): """ Black and white processing :param file_path: :return: """ video = VideoFileClip(file_path) file_path_new = "/Users/xingag/Desktop/new.mp4" video.fx(vfx.blackwhite).write_videofile(file_path_new)In addition to the above several video modification methods , You can also use CV2 and MoviePy, Add some special templates 、 The end of the clip has a gradient animation to ensure the originality and uniqueness of the video .
