How to batch download and save online videos for free?

In today's digital age, online video has become an important way for people to obtain information and entertainment. However, sometimes we want to save these videos to the local device for offline viewing or other purposes. Today, we will discuss how to batch download and save online videos for free.

Basic steps for online video downloading

First of all, what needs to be determined is that not all websites allow users to download their video content, which may involve copyright issues. So before trying to download any video, make sure you have the legal right to do so. Once the download is confirmed, you can follow these steps:

1. Use online video download tools

There are many online tools that can help you download videos easily. A well-regarded tool is “SaveFrom.net”. Its use is very simple:

Visit SaveFrom.net official website.

Copy the link to the video you want to download into the SaveFrom.net search box.

Click the "Download" button, select your desired video quality, and start downloading.

2. Use browser plug-ins

In addition to online tools, you can also use some browser plug-ins to download videos. For example, "Video DownloadHelper" is a very popular Firefox and Chrome browser plug-in that can automatically detect videos on web pages and provide download options.

For Firefox users, Video DownloadHelper can be installed directly from Firefox's Add-ons Market.

For Chrome users, you can download and install the plug-in from the Chrome Web Store.

Once installed, the plug-in icon will appear on your browser toolbar when you visit a web page that contains videos. Click the icon and the plug-in will automatically identify the video files on the page and provide download options.

Download videos in batches

If you need to download multiple videos, downloading them one by one manually can be very time-consuming. At this point, consider using automated scripts or batch download tools to simplify the process. However, be aware that such tools may involve more complex setup and operation.

Using Python script

For users with a certain programming foundation, you can write a simple Python script to download videos in batches. Python has many powerful libraries, such as youtube-dl or pytube, that can easily handle video downloading tasks.

First, you need to install Python. Visit the Python official website (https://www.python.org/) to download the version suitable for your operating system.

After the installation is complete, install the pytube library through the command line: pip install pytube

Next, write a simple script that reads a text file containing links to videos and then uses pytube to download those videos.

Here is a simple sample code:

`python

from pytube import YouTube

with open('video_links.txt', 'r') as file:

links = file.readlines()

for link in links:

yt = YouTube(link.strip())

video = yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first()

video.download()

`

In this example, video_links.txt is a text file containing all the video links, one link per line. The above script will download these videos in sequence.

Conclusion

Through the above methods, you can download and save online videos in bulk for free and legally. Whether using online tools, browser plug-ins, or writing scripts, there are many ways to meet your needs. But remember, always respect copyright regulations and download only those video content that is allowed to be downloaded.
