Today I will talk to you about a topic that everyone is more concerned about when making video content, video deduplication, first of all, let’s align and define, what is video deduplication?
What is video plagiarism check?
Video plagiarism check, as the name suggests, is a technical means designed to prevent the same or similar videos from being uploaded repeatedly on online video platforms, thereby improving copyright protection and content security. The main purpose of video deduplication is to detect the similarity of video content, determine whether the video is duplicated or nearly duplicated with other videos already on the platform, and then delete or block them.
Video plagiarism check usually uses image recognition technology and audio recognition technology, by extracting the image frame and audio information in the video, converting them into digital features for comparison, so as to determine the similarity between videos. Some online video platforms, such as YouTube and TikTok, have adopted their own video deduplication algorithms and techniques to ensure that the content on the platforms complies with copyright requirements and community guidelines.
Then video deduplication is a means or method to combat video duplication checking.
Now that we already know what is video duplication checking and deduplication, then we need to understand in the next step, what are the common methods of duplication checking?
Common video plagiarism check methods mainly include the following:
- Duplicate checking algorithm based on content similarity: This algorithm judges the similarity between videos by calculating the feature code of the video content. When the feature code similarity of two videos exceeds a certain threshold, it will be judged as a duplicate video.
- Duplicate checking algorithm based on frame difference: This algorithm judges the similarity between videos by comparing the differences between video frames. When the frame difference of two videos exceeds a certain threshold, it will be judged as a duplicate video.
- Duplicate checking algorithm based on audio fingerprint: This algorithm judges the similarity between videos by calculating the fingerprint information of the audio in the video. When the audio fingerprint similarity of two videos exceeds a certain threshold, it will be judged as a duplicate video.
- Duplicate checking algorithm based on video metadata: This algorithm judges the similarity between videos by comparing metadata information of videos, such as file size, creation time, modification time, etc. When the metadata similarity of two videos exceeds a certain threshold, it will be judged as a duplicate video, etc.
What needs to be emphasized here is that at present, most platforms do not use a single algorithm to make judgments. They are all combined or other models. Here are just a few relatively common algorithms.
Common Deduplication Methods
We know the algorithm model of duplicate checking, so let's learn some methods of deduplication in a targeted manner, just for everyone to learn! ! ! !
For video duplication check, there are some methods to process the video, so as to avoid being checked for duplication:
- Modify the video size and resolution: By changing the size and resolution of the video, it can make the video look different from the original video, thereby interfering with the judgment of the plagiarism checking algorithm.
- Changing the video format and encoding method: The video format and encoding method will affect the file size and quality of the video. Changing the video format and encoding method can change the feature code of the video, thereby interfering with the judgment of the plagiarism checking algorithm.
- Add or modify video audio: By adding or modifying video audio, you can change the feature code of the video, so that the video is different from the original video.
- Watermarking the video: By adding a watermark to the video, the feature code of the video can be changed, thereby interfering with the judgment of the duplicate checking algorithm.
- Cutting or editing the video: By cutting or editing the video, part of the content of the video can be deleted or modified, thereby interfering with the judgment of the plagiarism checking algorithm
- Regenerate subtitles or dubbed commentary
- Add extra stickers, text, etc.
It is important to note that different platforms may use different plagiarism algorithms, so there is no simple way to circumvent plagiarism. In addition, the duplicate checking algorithm is constantly being upgraded and improved, so avoiding duplicate checking is not an easy task. If you want to publish a video on the Internet, it is recommended to use your own original content as much as possible, and avoid using other people's video, audio, pictures and other materials to ensure that the video will not be judged as a duplicate video.
In addition, we said that all the above-mentioned deduplication methods require you to spend time or have a certain editing ability. In theory, the greater the proportion of your body and intelligence in content creation, the more original your content will be. The higher you are, the more you can deeply understand the meaning of this sentence.
So for all the deduplication methods mentioned above, is there any software that can automatically complete it for you? There is really one, the online video editing product under JollyToday, GhostCut, which can automatically complete the video content Deduplication, double speed, acceleration and deceleration, pinch head and tail, mirror image, frame extraction, picture-in-picture, sharpening filter, transition sticker special effects and many other deduplication methods, fully automatic processing, and even automatic removal Watermark or text in the video, translate Chinese video into English, greatly improve production efficiency.
