If you have permission to use a video uploaded by someone else, you may want to save a copy and make a few changes before sharing it or keeping it for your own project. This guide shows you how to download an authorized copy and make simple edits with one Windows program.
YouTube Studio offers basic editing for videos you have uploaded, but it cannot edit another creator's video in place. If you have the right to use that video, you can work with a permitted local copy in a third-party editor instead.
The workflow has two parts: first, save the video to your computer when downloading is permitted; then make the edits you need. Once the file is saved, you can import it into the Converter to edit individual videos or join multiple clips.
Before you begin: A video being public on YouTube does not mean it is free to download, edit, or repost. Make sure you have the necessary rights and that downloading complies with YouTube's Terms of Service or applicable law. If a video has a Creative Commons license, follow its conditions, including attribution; simply giving credit does not replace permission.
How to Edit a YouTube Video That Is Not Yours
WonderFox HD Video Converter Factory Pro combines a video downloader and a basic editor for Windows. Once you have a video you are allowed to use, you can cut and split clips, rotate or flip footage, crop the frame, merge videos, and add filters, watermarks, or metadata. It also offers 500+ output presets for popular formats and devices.
If you have an authorized YouTube video to edit, you can use the Downloader in WonderFox HD Video Converter Factory Pro to save a local copy, where supported. The same software lets you edit the downloaded file, so you do not need to move between different desktop programs. If the creator has already supplied the original video file, skip this part and import that file directly into the Converter.
Copy the URL of the video you are permitted to download. Open the software and select “Downloader” > “New Download.” Paste the link and click “Analyze,” or use “Paste and Analyze” directly.
If the video is available for downloading, select a suitable option under the “Download Video” tab. Choose a resolution that meets your editing needs, then click “OK” to add the task.
Choose where to save the file and click “Download All.” When it finishes, you can open the downloaded video in the Converter.
After downloading the video, you can do all the basic editing in the same program. Use the editing toolbar below each imported video for individual changes, or use the Merge option at the top when you need to join multiple files.
Close the Downloader and open the “Converter” module.
Click “Add Files” or drag and drop your downloaded videos into the window.
Add at least two files if you plan to merge them.
Use the editing toolbar below each video to cut or split clips, rotate or flip the picture, crop unwanted areas, add built-in filters or watermarks, and edit metadata. For example, click the scissors icon to open the trimming window, set the start and end times, click “Trim” to keep the selected section, and repeat if you want several clips from one video. Click “OK” when you are done.
If you want to combine videos, click “Merge” at the top of the Converter (at least two files are required). In the Merge window, add the clips to a pack, arrange them in your preferred order, and confirm the merge. You can edit individual clips before combining them.
Click the output format image on the right if you need a different format or device preset. Choose a destination folder using the inverted triangle at the bottom, then click “Run” to save your edited video.
Q1. Can I edit someone else's video directly in YouTube Studio?
No. YouTube Studio's editor works with videos uploaded to your own channel. To edit another creator's footage, you need a copy you are permitted to use and a separate editor. YouTube Studio also does not offer a tool for joining separate uploaded videos.
Q2. Can I edit the downloaded video online instead?
Yes. If you have an authorized file, browser-based editors such as 123apps or Clipchamp provide basic editing options. Check their file limits, export restrictions, and privacy terms before uploading footage.
Q3. What if I want to edit videos on a Mac, iPhone, or iPad?
You can import video files into iMovie, make your edits on the timeline, and export the finished movie. WonderFox HD Video Converter Factory Pro in the main tutorial is for Windows.
At last...
The process is straightforward: save a video you are permitted to use, import it into the Converter, and edit it with the toolbar or merge it with other clips. HD Video Converter Factory Pro handles these basic editing tasks in one Windows program. Before sharing the result, make sure your intended use is covered by the rights you have.
