1, video editing software
Video editing software can edit and process videos in various ways, including changing the background. Common video editing software includes Adobe Premiere Pro and Final Cut Pro. Take Adobe Premiere Pro as an example, open the software, import a small video and drag it to the timeline. Then, drag the new background material to the timeline and cover it with a small video.
Select the "Keying" function in the "Effect Control" panel, adjust the "Keying" effect, keep the parts that need to be kept, and remove the parts that need to be removed. Finally, merge the cut background with the new background.
2. Online video editing website
The online video editing website can be used directly in the browser without downloading and installing. Such websites usually provide relatively simple video editing functions, including changing the background. Take a common online video editing website as an example, open the website to upload your small video, select "Add Effect" or similar function, and then select "Thumbnail" or similar option.
Under the matting function, the system will automatically identify people or things in the video and keep them. Then, select the replace background function to merge the cut background with the new background. Finally, just save and download your video.
3. Use software such as AE or PS.
If you are familiar with the use of video editing software, you can use software such as AE or PS to change the video background. In AE, you can use the Tracking Mask function to track people or objects in the video and pull out their masks. Next, add a new background and put it at the bottom.
In PS, you can use selection tools such as "Quick Selection Tool" or "Magnetic Lasso Tool" to pick out people or objects and merge them with the new background. Finally, just export your little video.
4. Use green screen technology
Green screen technology is a common method of video background transformation. This method needs to use green background cloth or green paper as the background when shooting, so as to make matting later. After shooting, use video editing software to cut off the green background and replace it with a new background. This method requires professional shooting skills and post-processing skills, but it can achieve ideal results.
