Many people need to edit when creating videos, such as deleting useless shots, adjusting the length of the video, etc. These tasks usually require the use of video editing software, such as Adobe Premiere and Final Cut Pro. However, if you want to edit a large number of videos in batches, or want to edit videos programmatically, Python will provide you with a convenient solution.
In this article, we will introduce a complete guide on how to use Python for video editing. We will explore how to use Python libraries FFmpeg and MoviePy to cut, merge and convert videos.
Install FFmpeg
FFmpeg is a popular open source software that can be used to process video and audio files. Since we will use the Python library FFmpeg for video editing, we need to install FFmpeg first.
Windows
On Windows, you can download the precompiled binary file and add it to the system path. You can go to FFmpegOfficial websiteDownload the Windows version of FFmpeg. Then add the bin folder to your system PATH environment variable.
MacOS
On MacOS, you can use Homebrew to install FFmpeg. Open the terminal and execute the following command:
brew install ffmpeg
Ubuntu
On Ubuntu, you can use apt to install FFmpeg. Open the terminal and execute the following command:
sudo apt update sudo apt install ffmpeg
Install MoviePy
MoviePy is a Python library for processing video and audio files. It builds on FFmpeg and ImageMagick and provides advanced features such as cutting, resizing, merging videos and adding text.
You can use pip to install MoviePy. Open the terminal and execute the following command:
pip install moviepy
Cut video
Cutting videos with MoviePy is very simple. Here is an example of cutting the video from the 10th to 20th:
from import VideoFileClip # Define editing time periodstart_time = 10 # Start time, unit in secondsend_time = 20 # End time, unit in seconds # Read video files and editvideo = VideoFileClip("video.mp4").subclip(start_time, end_time) video.write_videofile("cut_video.mp4")
Since MoviePy is based on FFmpeg and ImageMagick, it can handle a variety of video formats, such as MP4, AVI, and MOV.
Merge videos
Merging videos with MoviePy is also very simple. Here is an example of combining two video files together:
from import VideoFileClip from import resize # Read the video file to be combinedvideo1 = VideoFileClip("video1.mp4") video2 = VideoFileClip("video2.mp4") # Resize videos to make sure they have the same sizevideo1_resized = resize(video1, height=480) video2_resized = resize(video2, height=480) # Merge two video files togetherfinal_video = concatenate_videoclips([video1_resized, video2_resized]) # Save the resulting video filefinal_video.write_videofile("merged_video.mp4")
Convert videos
Converting a video file from one format to another is very simple using MoviePy. Here is an example of converting MP4 videos to WMV videos:
from import VideoFileClip # Read MP4 video filesvideo = VideoFileClip("video.mp4") # Convert video format to WMVvideo.write_videofile("")
in conclusion
The above is the complete guide to using Python for video editing. With FFmpeg and MoviePy, you can easily edit, merge and convert video files. The most important thing to remember when editing a video file is to always keep the original video copy. This avoids accidentally destroying your original material so that you can re-edit the requirements later.
