Keying classification

Keying can be divided into two categories: video keying and picture keying.

The purpose of video keying is to blend the foreground into the background when editing the video, and use the keying technology to remove the background, so as to realize the synthetic editing with the new background. Studio shooting usually uses blue or green background. Image keying is simpler than video, and the greater the color contrast between the background and the actor's clothes and skin, the better, so keying is easier to realize.

How is Aauto Quicker's video keyed? Before changing the video background, you need to prepare two kinds of materials: 1, and prepare a portrait short film with green screen or blue screen. However, it is not difficult to shoot it yourself. Hang a green (or blue) background cloth on the wall and spread the hanging part on the ground. Shoot a short character film in the center of a green (or blue) background. 2. Prepare a high-resolution picture, clear, what kind of pictures and videos you need, as long as you want to match them, so that you can see the effect after fusion. 3. After preparing these two materials, open the running software. In the main interface of the software, select Insert Background and click Browse to find and select the background image material in the computer directory. If pictures cannot be displayed in the directory, please select "Still Image File" as the following file type to display picture files. As shown in the figure below:

4. As in the previous step, select the video file of "Input Clip" and open "Browse" to find the selected video material in the computer directory. If your video material can't be displayed in the directory, the video format must be one of the file types "avi, mov, mpeg, MPG, MXF, M2T, MLV, MPE, IVF, SMV", otherwise you can't add video. As shown in the following figure: 5. After the video and background image materials are successfully added, click the key mark under the preview window. Click the key points in different positions of the green background in the preview with the mouse first, and remove the background color (pay attention to multiple choices, especially the points with uneven background color must be selected). 6. After selecting the key points, select the first "Key" menu in the menu bar below, and click "Enable" below. The preview window on the right will show the picture with the green background of the video cut off, just like the picture below shows only the cat in the video. If the display cannot be enabled by clicking the key below, click the "One-key Keying/Application Point" preview window in the "Toolbox" at the top to display the picture with the green background of the video cut. 7. After removing the green background, some text watermarks, such as icons, will inevitably be left in the original video. At this time, you can erase the watermark with an erasing tool. If you want to erase it in the preview screen on the left, the preview window on the right will show the erasing effect. If you find that the background is not cleaned, you can adjust the edge reduction, edge softening, edge sharpening and sharpening range under reprocessing in the keying menu. As long as these parameters are adjusted, the background can be removed. 8. The next step is to adjust the position and size of the cat in the video. Move the cat's position in "Coordinates in Scene" in the "Scene" menu, and "Orientation in Scene" can set the orientation direction of the cat, and any angle orientation can be set. Move left and right in Size in Scene to set the size of the cat. 9. If everything is set up and there is no problem, you can output the video. In the Output menu, click Browse to select the folder directory where the video is saved in the save path window. You can rename the video and click Save. Finally, click Save Output.

10. After clicking Save Output in the previous step, the output progress will be displayed in the progress area. Remember not to close the software at this time, which can reduce the interface of the software. After the progress bar is displayed in full green, the output video is complete!

1 1. After the output is completed, find the video in the folder where the video is saved, and play the video with the video player, such as Storm Video, and play the converted video. Video replacing background is fun and can be used to make interesting videos. You can change the background of the video at will, whether it is dynamic or static. You can also insert music into the video. This software is not only better than the general editing software, but also has a good effect!

Knowing what you want is not a big problem, just a good one. Use your mobile phone.
